Available in PDF, EPUB and Kindle. Book excerpt: Automatically tracking and recognizing human faces in videos and live streams is often a crucial component in many high-level applications such as security, visual surveillance and human-computer interaction. Deep learning has recently revolutionized artificial intelligence areas, including face recognition and detection. Most of the existing video analysis solutions, however, rely on certain 2D convolutional neural network (CNN) to process video clips upon a frame-to-frame basis. The temporal contextual information between consecutive frames is often inadvertently overlooked, resulting in inconsistent tracking outcomes, which also negatively affect the accuracy of human identification. To provide a remedy, we propose a novel network framework that allows history information be carried along video frames. More specifically, we take the single short scale-invariant face detection (S3FD) as the baseline face detection network and combine it with long short-term memory (LSTM) components to integrate temporal context. Taking the images and detection results of previous frames as additional inputs, our S3FD + LSTM framework is well posed to produce more consistent and smoother face detection results along time, which in return leads to more robust and accurate face recognition in videos and live streams. We evaluated our face tracking and recognition model with both public (YouTube Face) and self-made datasets. Experimental results demonstrate that our S3FD+LSTM approach constantly produces smoother and more stable bounding boxes than S3FD alone. Recognition accuracy is also improved over the baseline model, and our model significantly outperforms the state-of-the-art face tracking solutions in the public domain.

Book excerpt: Automatic face recognition has a lot of application areas, such as biometrics, information security, law enforcement, surveillance; smart cards and access control etc. Current single-camera face recognition has severe limitations when the subject is not cooperative, or there are pose changes and different illumination conditions. Face recognition using multiple synchronized cameras is proposed to overcome the limitations in this dissertation. The major contributions include illumination insensitive change detection, component-based single-channel face detection and recognition, and a fusion approach to effectively combine the multiple channels running the mentioned face detection and recognition. The illumination insensitive change detection is motivated from a statistical model derived from the physics of the imaging process, detects changes by examining the order consistency in the neighborhood that is resistant to sudden illumination changes, and can be used as a peripheral subsystem to work with face detection and recognition. The face detection is based on two levels of processing, in which the first level detects the face components using improved AdaBoost, and the second level fuses individual component detections to detect a face using a component face model. This approach is robust to face pose and illumination changes and fast compared to other face detection algorithms. The detected face is recognized by an LDA based face recognizer with fusion over time to further improve robustness. For the two-channel system, a reliability measure is effectively trained for each channel with features extracted from both face detection and recognition results, and it accurately chooses the more reliable channel as the final face recognition. The performance in terms of recognition rate is far better than that of either single channel, and it is consistently better than common classifier fusion rules. Future work will focus on joint similarity modeling to explore information hidden in all matching scores in all channels for better performance.

Download or read book Face Recognition from Video written by Joshua David Harguess and published by . This book was released on 2011 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the area of face recognition has been extensively studied in recent years, it remains a largely open problem, despite what movie and television studios would leave you to believe. Frontal, still face recognition research has seen a lot of success in recent years from any different researchers. However, the accuracy of such systems can be greatly diminished in cases such as increasing the variability of the database, occluding the face, and varying the illumination of the face. Further varying the pose of the face (yaw, pitch, and roll) and the face expression (smile, frown, etc.) adds even more complexity to the face recognition task, such as in the case of face recognition from video. In a more realistic video surveillance setting, a face recognition system should be robust to scale, pose, resolution, and occlusion as well as successfully track the face between frames. Also, a more advanced face recognition system should be able to improve the face recognition result by utilizing the information present in multiple video cameras. We approach the problem of face recognition from video in the following manner. We assume that the training data for the system consists of only still image data, such as passport photos or mugshots in a real-world system. We then transform the problem of face recognition from video to a still face recognition problem. Our research focuses on solutions to detecting, tracking and extracting face information from video frames so that they may be utilized effectively in a still face recognition system. We have developed four novel methods that assist in face recognition from video and multiple cameras. The first uses a patch-based method to handle the face recognition task when only patches, or parts, of the face are seen in a video, such as when occlusion of the face happens often. The second uses multiple cameras to fuse the recognition results of multiple cameras to improve the recognition accuracy. In the third solution, we utilize multiple overlapping video cameras to improve the face tracking result which thus improves the face recognition accuracy of the system. We additionally implement a methodology to detect and handle occlusion so that unwanted information is not used in the tracking algorithm. Finally, we introduce the average-half-face, which is shown to improve the results of still face recognition by utilizing the symmetry of the face. In one attempt to understand the use of the average-half-face in face recognition, an analysis of the effect of face symmetry on face recognition results is shown.

This book was released on 2006-01-01 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recognition of humans and their activities from video sequences is currently a very active area of research because of its applications in video surveillance, design of realistic entertainment systems, multimedia communications, and medical diagnosis. In this lecture, we discuss the use of face and gait signatures for human identification and recognition of human activities from video sequences. We survey existing work and describe some of the more well-known methods in these areas. We also describe our own research and outline future possibilities. In the area of face recognition, we start with the traditional methods for image-based analysis and then describe some of the more recent developments related to the use of video sequences, 3D models, and techniques for representing variations of illumination. We note that the main challenge facing researchers in this area is the development of recognition strategies that are robust to changes due to pose, illumination, disguise, and aging. Gait recognition is a more recent area of research in video understanding, although it has been studied for a long time in psychophysics and kinesiology. The goal for video scientists working in this area is to automatically extract the parameters for representation of human gait. We describe some of the techniques that have been developed for this purpose, most of which are appearance based. We also highlight the challenges involved in dealing with changes in viewpoint and propose methods based on image synthesis, visual hull, and 3D models. In the domain of human activity recognition, we present an extensive survey of various methods that have been developed in different disciplines like artificial intelligence, image processing, pattern recognition, and computer vision. We then outline our method for modeling complex activities using 2D and 3D deformable shape theory. The wide application of automatic human identification and activity recognition methods will require the fusion of different modalities like face and gait, dealing with the problems of pose and illumination variations, and accurate computation of 3D models. The last chapter of this lecture deals with these areas of future research.

Download or read book Face Recognition for Real Time Application written by Pradeep Kakkar and published by GRIN Verlag. This book was released on 2017-11-27 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2017 in the subject Engineering - Computer Engineering, grade: 10, , course: M.Tech-ECE, language: English, abstract: Images containing faces are essential to intelligent vision-based human computer interaction, and research efforts in face processing include face recognition, face tracking, pose estimation, and expression recognition. The rapidly expanding research in face processing is based on the premise that information about a user’s identity, state, and intent can be extracted from images and that computers can then react accordingly, e.g., by knowing person’s identity, person may be authenticated to utilize a particular service or not. A first step of any face processing system is registering the locations in images where faces are present. The local binary pattern is a simple yet very efficient texture operator which labels the pixels of an image by thresholding the neighborhood of each pixel and considers the result as a binary number. The LBP method can be seen as a unifying approach to the traditionally divergent statistical and structural models of texture analysis. Perhaps the most important property of the LBP operator in real-world applications is its invariance against monotonic gray level changes caused, e.g., by illumination variations. Another equally important is its computational simplicity, which makes it possible to analyze images in challenging real-time settings. The success of LBP in face description is due to the discriminative power and computational simplicity of the LBP operator, and the robustness of LBP to mono-tonic gray scale changes caused by, for example, illumination variations. The use of histograms as features also makes the LBP approach robust to face misalignment and pose variations. For these reasons, the LBP methodology has already attained an established position in face analysis research. Because finding an efficient spatiotemporal representation for face analysis from videos is challenging, most of the existing works limit the scope of the problem by discarding the facial dynamics and only considering the structure. Motivated by the psychophysical findings which indicate that facial movements can provide valuable information to face analysis, spatiotemporal LBP approaches for face, facial expression and gender recognition from videos were described.
