Fig. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. But they do have some limitations like pose variation; aging etc cant be solved by thermal images. So, to solve different challenges faced while using visual images in face recognition systems, thermal images are used because of (Kong et al., 2005): Face (and skin) detection, location, and segmentation are easier when using thermal images. It is clear that thermal emission patterns around the eyes, nose and mouth are rather different in different sessions. These foresaid characteristics have made SWIR useful even in the area of face recognition. 8001280res. Application of new imaging modalities such as near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR) and long-wave infrared (LWIR) has recently opened up new opportunities for research in the area of IR face recognition [], which is usually encountered in monitoring . Ideally, we need something a little more robust and flexible. In addition, infrared cameras can image in complete darkness, so infrared face recognition technology has a hardware foundation that can perform face recognition at night. The algorithms were parametrized using different methods to analyze the impact of algorithm modifications on tracking performance. Thermal infrared face recognition helps recognize faces that are not able to be recognized in visible light and can additionally recognize facial blood vessel structure. Please note that Cureus is not responsible for any content or activities contained within our partner or affiliate websites. 3D face mapping is also limited to short distances, and, again, it can struggle to adapt to changing facial characteristics either and doesnt always work as well in brighter lighting conditions. This implies that an additional degree of filtering and intelligence is to be applied to the pixel streams to present pertinent information to the user. It has many physiological clues that photo does not have, such as head movement, facial expression, blinking etc. Symptoms such as alertness and anxiety can be used as a biometric, which is difficult to conceal as redistribution of blood flow in blood vessels causes abrupt changes in the local skin temperature. The use of Analytic Wavelet Transform (AWT) is more beneficial over Mallat wavelet transform, as AWT is translation invariant in nature[13]. At sunrise SWIR cameras provide effective imaging day and night thus eliminating thermal crossover. Objective of this chapter is to introduce the role of different IR spectrums, their applications, some interesting critical observations, available thermal databases, review works, some experimental results on thermal faces as well as on fused faces of visual and thermal face images in face recognition field; and finally sorting their limitations out. Table 5 is furnished with the Terravic Facial Infrared database (http://cse.ohio-state.edu/otcbvs-bench/Data/02/download) overview. Another advantage of visual image is that the visual cameras are less. 3: Output of the current analysis module, in this case, a breathing rate analysis. (b) The short wave infrared (SWIR) imagery (http://sensorsinc.com/nightvision) of the same scene under the same conditions using a Goodrich camera. Holistic appearance methods use the entire infrared appearance image of a face for recognition. Classical inference; computing a joint probability given an assumed hypothesis usually using Maximum A Posteriori (MAP) or maximum likelihood decision rules. IEEE J Biomed Health Inform. Liveness detection, which aims at recognition of human physiological activities as the liveness indicator to prevent spoofing attack, is becoming a very active topic in field of fingerprint recognition and iris recognition. So, the main aim is to tackle all these problems to give an accurate automatic face recognition. 'Infrared' (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which equates to a frequency range between approximately 1 and 430 THz. Socolinsky et al. Human face has other additional features like expression, appearance, adornments, beard, moustache etc. It contains images of 30 individuals (28 men and 2 women). Lecture Notes in Computer Science. Constructive Auto-associative Neural Network (CANet), which is a novel neural network inspired by neural biology, has been proposed. 456468. Face Recognition Infrared Thermometer German termal imaging sensor. Learn more. The AI-based recognition system can still verify a face based on visible features, such as eyes. The results improve significantly in the verification and identification performance and the success rate is 97.05% over the OTCBVS database (Bhowmik et al., 2008). Thermal face recognition deals with the face recognition system that takes thermal face as an input. What is the set of images of an object under all possible lighting conditions? Total no. This site needs JavaScript to work properly. developed a face recognition technique with PCA. O'Toole AJ, Castillo CD, Parde CJ, Hill MQ, Chellappa R. Trends Cogn Sci. Best viewed electronically, AAM:Active Appearance Model;DAN:Deep Alignment Network. However, there has been little effort on interpreting thermal images of outdoor scenes based on a study of the mechanism that gives rise to the differences in the thermal behavior of object surfaces in the scene. Hence why so few manufacturers include the technology. The active light source will produce obvious reflections on the glasses, reducing the accuracy of eye positioning. These feature vectors are often fused to form joint feature vectors from which the classification is made. This database has disguise faces too. Infrared face recognition is a solution to solve the illumination problem in face recognition. This study continues a previous face recognition investigation using uncooled infrared technology. Visual images are unable to detect disguise. Ideally, the fusion of common pixels can be done by pixel-wise weighted summation of visual and thermal images (Horn & Sjoberg, 1979), as below: where, F(x, y) is a fused output of a visual image, V(x, y), and a thermal image, T(x, y), while a(x, y) and b(x, y) represent the weighting factors for visual and thermal images respectively. As a part of future work of the foresaid thermal face mosaicing, the mosaiced faces are experimented for face recognition purpose where we are checking the similarity between mirror face images and normal face images. IEEE Trans Pattern Anal Mach Intell. Qualitative overview of fitting performance, From left to right: Original image, fast AAM, Figure 5. The system may use a camera having multi-band detection capabilities. Our team is growing all the time, so were always on the lookout for smart people who want to help us reshape the world of scientific publishing. The combination of AI and multiple images also allows the technology to recognize mask-wearing faces, albeit with increased false acceptance and rejection rates. Not only the computer scientists, but the neuroscientists and psychologists are also taking their interests in the field of development and improvement of face recognition. HHS Vulnerability Disclosure, Help The range beyond 14m is termed the very long-wave infrared (VLWIR) and although in recent years it has received increased attention. (Authors cannot rate their own articles.). Both NIR and SWIR have been found to have advantages over imaging in the visible for face detection (Dowdall et al., 2002) and detecting disguise (Pavlidis & Symosek, 2000). abide by the contract", conforms to the market requirement, joins during the market competition by its superior quality also as provides extra comprehensive and exceptional service for consumers to let them turn into significant winner. Previous research regarding temperature variations, mathematical formulas, wave types, and methods in thermal infrared face recognition is reviewed. Recent research has demonstrated distinct advantages of using thermal infrared imaging for improving face recognition performance. Careers. Weidlich V A (March 06, 2021) Thermal Infrared Face Recognition. By Shylaja S. Sharath, Balasubramanya Murthy K N and Natarajan S. 2011 The Author(s). Having so many applications of this interesting area, there are challenges as well as pros and cons of the systems. Face recognition using infrared In this review, we recognize four main groups of face recognition methodologies which use infrared data: holistic appearance based, feature based, multi-spectral based, and multi-modal fusion based. This neural network uses receptive fields for implicit feature extraction, lateral inhibition, and auto-associative memory for image reconstruction. In the first method log-polar transformation is applied to the fused images, which are obtained after fusion of visual and thermal images, whereas in second method fusion is applied on log-polar transformed individual visual and thermal images. Consistent features can be defined as features that are present in three or more thermal signatures from images taken at different times. Their thermal detectors only show the presence of warm objects against a cooler background. Previous research regarding temperature variations, mathematical formulas, wave types, and methods in thermal infrared face recognition is reviewed. Thermal images can be a solution to the spoofing problem and detecting live faces as it captures only the heat emitted and so the thermal images generated from the emitted heat by a photograph or a video will be totally different from the thermal image of an original human face. Passive infrared camera technology is rarely used because of the high cost of equipment and the inability to reflect the surrounding environment. A. Guzman, M. Goryawala, J. Wang, et al. artificial intelligence; blood vessel pattern; deep learning; face recognition; facial vascular pattern; long wave infrared; machine learning; neural networks; thermal infrared imagery; vascular map. Because polysilicon is also suitable as an absorber, they can also be made from polysilicon as MEMS and combined with evaluation circuits in CMOS technology. This makes objects easily recognizable and yields one of the tactical advantages of SWIR, namely, object or individual identification (http://www.sensorsinc/whyswir). 10,000 People Infrared Face Recognition Data. Fig. The range of human face and body temperature nearly same and quite uniform, varying from 35.5C to 37.5C providing a consistent thermal signature. Radiometric calibration was found to provide non-uniformity correction. Employed clandestinely, SWIR imaging can add a very valuable layer of protection in the defense of the homeland. Widely used methods for decision level fusion include the following: Bayesian inference (Information theory, inference and learning algorithms, book by David Mackay). 1: Live video view with overlaid landmarks from the automated ShapeNet landmark detection (red) and their respective bounding box corners (blue). Thermal images show great usability for facial recognitionsince their sensitivity to illumination changes is low. For facial expression recognition they use the IRIS dataset. Thus, when built as focal plane arrays with thousands or millions of tiny point sensors, or sensor pixels, SWIR cameras will work in very dark conditions (http://www.sensorsinc/whyswir). For achieving better recognition rate, an image fusion technique based on weighted average of Daubechies wavelet transform (db2) coefficients from visual face image and their corresponding thermal images have been conducted. Pixel level fusion is the combination of the raw data from multiple source images into a single image. The database developed in an earlier study is further expanded to include 50 volunteers with 30 facial images from each subject. PINs from massive ATMs made their way to lock-screens, and fingerprint scanners from bulky accessories and laptops are now small enough to embed under a phones display. Android RK3288 Chip. IR face recognition systems are unaffected by variations in illumination and unlike systems using visual light, they can work without any problem under all lighting conditions, even in complete darkness. It is well-known that under the assumption of Lambertian reflection, the set of images of a given face acquired under all possible illumination conditions is a subspace of the vector space of images of fixed dimensions [10]. Anatomical features of faces, useful for identification, can be measured at a distance using passive IR sensor technology with or without the cooperation of the subject (Gupta & Majumdar). A. Guzman, M. Goryawala, J. Wang, et al. Bethesda, MD 20894, Web Policies While all registered Cureus users can rate any published article, the opinion of domain experts is weighted appreciably more than that of non-specialists. In face recognition, sometimes visual images are found to be more helpful than thermal images. For accurate and effective face recognition we require more informative images. Trinamix has also been working with Qualcomm to run its mapping algorithms on Snapdragon Hexagon DSPs. Key benefits and capabilities of Windows Hello face authentication These are the key benefits to using the Windows Hello face authentication: Infrared sensors can detect your facial features even in dimly-lit environments. For face recognition in the thermal infrared, this is a turning point as for the first time the most appropriate thermal infrared imaging technology (i.e. Open Access is an initiative that aims to make scientific research freely available to all. Previous research regarding temperature variations, mathematical formulas, wave types, and methods in thermal infrared face recognition is reviewed. They found that the emissivity of the imaged object provides the further advantage of data where environmental factors contribute to a much lesser degree to within-class variability. doi:10.7759/cureus.13736. No contact temperature measurement. Face Recognition in the visible spectrum is a widely used biometric tool. If you need data services, please feel free to contact us: info@datatang.com, Terms Privacy 2021 Datatang. In this category, plurality voting is the most commonly used one that just outputs the class label having the highest vote. The interpretation of each type of image thus leads to ambiguous inferences about the nature of the objects in the scene. A comprehensive and timely review of the literature on infrared (IR) imaging has emerged as a particularly promising research direction for automatic face recognition. Database images having the format of bmp color images are 320 x 240 pixels in size. Since the feature set contains richer information about the raw biometric data than the match score or the final decision, integration at this level is expected to provide better recognition results. This mosaiced image can further be imputed in any simple thermal face recognition system. Infrared face recognition is a solution to solve the illumination problem in face recognition. Previous research regarding temperature variations, mathematical formulas, wave types, and methods in thermal infrared face recognition is reviewed. (c) Thermal signature template of the subject. Infrared Face Recognition - Factory, Suppliers, Manufacturers from China. Federal government websites often end in .gov or .mil. Thermal infrared face recognition helps recognize faces that are not able to be recognized in visible light and can additionally recognize facial blood vessel structure. Features 1. Total 3058 images are available; 1529 images are thermal and other images are visual. Be it from simply unlocking your smartphone to registering access in and out of a secure office block. AI-based visual recognition ties the system together, which analyses this unique enhanced spectrum facial data for key facial profile features. Best viewed electronically Source: [6] AAM:Active Appearance Model;DAN:Deep Alignment Network, 1: Live video view with overlaid landmarks from the automated ShapeNet landmark detection (red) and their respective bounding box corners (blue). Type of that database is thermal in JPEG format. Visual images are considered to be the best in some cases like extracting and locating facial features easily. As PhD students, we found it difficult to access the research we needed, so we decided to create a new Open Access publisher that levels the playing field for scientists across the world. Please enable it to take advantage of the complete set of features! Its one of the reasons why we still recommend that the security-conscious use their phones fingerprint scanner rather than the face unlock feature. Here thermal and visual faces are fused together and then mosaicing is applied to construct apparent or complete profile view of an individual and then these mosaiced faces are classified using support vector machine classifier. In Fig. So, fusion of both thermal and visual images will generate a new fused image that will store the information of both thermal and visual faces. Source: [6], From left to right: Original image, fast AAM version, dynamic ShapeNet, fixed ShapeNet, high-quality AAM, boundary DAN, shape-DAN, and manual ground truth. In the vicinity of human body temperature (37 C), the Planck distribution has a maximum in the LWIR around 9m, and is approximately one-sixth of this maximum in the MWIR. Founded in 2011, Datatang is a professional AI data service provider and committed to providing high-quality training data and data services for global AI companies. Hence thermal imaging has great advantages in face recognition under low illumination conditions and even in total darkness (without the need for IR illumination), where visual face recognition techniques fail. Table 2 describes the problems in face recognition that can or cannot be solved using thermal images. Over the last few years, many researchers have investigated the use of thermal infrared face images for person identification to tackle illumination variation, facial hair, hairstyle etc. PMC See Figure 4. Thermal infrared face recognition helps recognize faces that are not able to be recognized in visible light and can additionallyrecognize facial blood vessel structure. So, simple concatenation of these two images (one is the original side view image and another is the mirror or opposite side view image) produces an apparent 2-D front face thermal mosaiced image of that person. Water absorption increases significantly at 1,450 nm. The range of body temperature varies from 96-100 degrees Fahrenheit (F)while skin temperature in ambient room temperature varies from 79-83 F. The periorbital regions are some of the hottest areas in the human face, which allows them to be used as a feature for face tracking. Haar-based features, Constructive Auto-associative Neural Network (CANet)) and Texture Histogramoffer the best results for some facial expressions [12]. LWIR ranges from 8-14 m (micro meter / micron). Smartphone examples include the Apple iPhone 12 series and as far back as Huaweis Mate 20 Pro. Some examples of infrared face images can be seen in Figure 1. In fact, all kinds of face recognition methods are similar, and the key lies in how to extract the identity characteristics from the face data, while eliminating the part affected by non-identity factors. Automatic face recognition (AFR) is an area with immense practical potential which includes a wide range of commercial and law enforcement applications, and it continues to be one of the most active research areas of computer vision.Even after over three decades of intense research, the state-of-the-art in AFR continues to improve, benefiting from advances in a range of different fields . When only one-sided semi profile thermal images of an individual are available, a mosaicing technique can be applied to build an apparent 2-D front profile view of that person (Majumder et al., 2011). RS232&Relay (can conect to acces gate and attendce system).

Accessibility : Pavlidis I, Tsiamyrtzis P, Buddharaju P, Manohar C: M. Kopaczka, L. Breuer, J. Schock, Merhof D: Carrapico R, Mouro A, Magalhes J, et al. All the classes dont contain each type of illumination. A ShapeNet was also used. The thermal infrared spectrum is divided into two primary spectra (Wolff et al., 2006) the MWIR and LWIR. Principal Component Analysis (PCA) techniques, also known as Karhunen-Loeve methods, choose a linear projection that reduces the dimensionality while maximizing the scatter of all projected samples [7]. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. Severe out-of-plane rotation may distort the frontalized image, however, as the image shows, the amount of acceptable rotation still covers most usual head poses. Figure 2. SIQ assesses article importance and quality by embracing the collective intelligence of the Cureus community-at-large. Currently, Supremas AI algorithms run on a graphics processor, but lower power consumption could be achieved by bringing these algorithms to neural processors instead. The proposed method works in three different steps. One of the most popular feature extraction algorithms along with multilayer perceptron (MLP) has been used for classification purpose over the OTCBVS database that leads to an optimal recognition result (Bhowmik et al., 2011). By performing morphological operations, like opening and top-hat segmentation to give thermal signatures, thermal feature extraction from facial images can be attained. Decision-level fusion schemes can be broadly categorized according to the type of information the decision makers output. For example, exposed to cold or wind, capillary vessels at the surface of the skin contract, reducing the effective blood flow and thereby the surface temperature of the face. proposed a TIR framework for face recognition that extracts unique features and finds similarity in thermal images [1]. In face recognition community, although numerous recognition approaches have been presented, the effort on anti-spoofing is still very limited. Haar-like transforms reduce time requirements in real-time object detection [14].

Mallat et al. A few experimental results with thermal images in face recognition are being recorded in Table 6. Furthermore, due to the more detailed and larger amount of facial features detectable with TIR, this method is expected to differentiate more quantitatively available facial features compared to visible light face recognition. The patterns of specific organs such as the eyes or parts thereof are used in biometric identification to uniquely identify individuals. IRIS (Imaging, Robotics and Intelligent System) Database Information. Illumination types available in this database are left light on, right light on, both lights on, dark room, left and right lights off with varying poses like left, right, mid, mid-left, mid-right. Recognition of individuals based on their facial appearance has been a subject of interest for many decades. The features extracted from visual intensity images also lack the specificity required for uniquely determining the identity of the imaged object. If we are thinking of keeping image as a part of biometric identity then it is very easy for someone to spoof an image and retrieve sensitive information from somebodys account and retrieve their valuable information by hacking their account. Numerous applications of it relate mainly to the field of security. (c) Thermal signature template of the subject. In the second step, feature vectors thus obtained are passed through eigenspace projection for the dimensionality reduction of feature vectors. To handle the challenges of face recognition that include pose variations, changes in facial expression, partial occlusions, variations in illumination, rotation through different angles, change in scale etc., two techniques have been applied. Such a system is typically employed to authenticate users through ID verification services, and works by pinpointing and measuring facial features from a given image.. Development began on similar systems in the 1960s, beginning as a form of computer . The technology for deep learning in the field of thermal infrared face recognition has recently become more available for use in research, therefore allowing for the many groups working on this subject to achieve many novel findings. In the first step, line features are extracted from thermal polar images and feature vectors are constructed using these lines. The face recognition system need to be able to recognize in different lighting environments. Though shortwave infrared lights interact with the objects similar way the light of visual wavelength does, human eyes cannot track the object in short wavelength. Image fusion methods mainly fall under two categories viz. InGaAs found early applications in the telecom industry as it is sensitive to the light used in long distance fiber optics communications, usually around 1550 nm. TIR face recognition is therefore expected to be more precise than visible light face recognition. The company also offers skin detection capabilities to assist with anti-spoofing. In preceding description, the concept of thermal images will be made clearer. 17 some image samples of Terravic Facial Infrared database are shown. By the late 1990s, uncooled micro bolometer imaging technology in the LWIR became more accessible and affordable, enabling wider experimental applications in this regime. They are also unaffected by skin color, suntan, use of cosmetics and colored . Current facial recognition technologies aren't the most secure security options, but AI and IR are about to change that. So, with a SWIR camera and this night radiance - often called nightglow - we can "see" objects with great clarity on moonless nights and share these images across networks as no other imaging device can do. Licensee IntechOpen. Support multiple language. The twins images in Fig. At that time, cooled MWIR technology was about ten times more sensitive than uncooled micro bolometer LWIR technology, and even though faces are more emissive in the LWIR, in the late 1990s MWIR could still discern more image detail of the human face. 2021-11-23 18:05:35.0. The Terravic Facial Infrared database contains total no. Their network is based on the use of contextual loss functions, enabling it to be inherently scale and rotation invariant. This helps to detect disguise, artificial hairs appear much darker than the original one, and sometimes it comes almost black. By Shylaja S. Sharath, Balasubramanya Murthy K N and By Milos Oravec, Jarmila Pavlovicova, Jan Mazanec, Lu IntechOpen Limited The https:// ensures that you are connecting to the It combines information into a single image from a set of image sources using pixel, feature or decision level techniques. See also: The best phones with in-display fingerprint scanners. Kopaczka et al. The radiation sensed is either emitted by an object at a non-zero absolute temperature, or reflected by it. While 2D infrared facial recognition is already leaps and bounds ahead of traditional camera-based. Generation of the thermal signature, Figure 7. Introduction Among the various recognition tasks in biometric technology, face recognition (FR) has received much attention in the field of computer vision. Legal statement and The thermal infrared (IR) spectrum comprises of mid-wave infrared (MWIR), and long-wave infrared (LWIR), all longer than the visible spectrum. So, in short, SWIR images are basically used because of high sensitivity, high resolution, seeing in the light of night glow or night sky radiance, day-to-night imaging, covert illumination, able to see covert lasers and beacons, no cryogenic cooling required, conventional and low-cost visible spectrum lenses, small size and low power. Log-polar transformed images are capable of handling complicacies introduced by scaling and rotation. Privacy Policy The training and testing sets of thermal images are registered in a polar coordinate that is capable to handle complicacies introduced by scaling and rotation and then polar images are projected into eigenspace and finally classified using a multi-layer perceptron. Active infrared camera technology uses a special infrared lamp to artificially generate infrared radiation, which is invisible to the human eye but can be captured by ordinary cameras, and to illuminate the scene and environment. But Visual images have some problems (Kong et al., 2005) with themselves: Visual images results in poor performance with illumination variations, such as in indoor and outdoor lighting conditions. However, fusion at this level is difficult to achieve in practice because of the following reasons: The feature sets of multiple modalities may be incompatible. Annu Rev Vis Sci. 6 shows an LWIR image. All Rights Reserved. Face images may be of different types like visual, thermal, sketch and fused images.
