People Identification and Tracking Through Fusion of Facial and Gait Features
نویسندگان
چکیده
This paper reviews the contemporary (face, gait, and fusion) computational approaches for automatic human identification at a distance. For remote identification, there may exist large intra-class variations that can affect the performance of face/gait systems substantially. First, we review the face recognition algorithms in light of factors, such as illumination, resolution, blur, occlusion, and pose. Then we introduce several popular gait feature templates, and the algorithms against factors such as shoe, carrying condition, camera view, walking surface, elapsed time, and clothing. The motivation of fusing face and gait, is that, gait is less sensitive to the factors that may affect face (e.g., low resolution, illumination, facial occlusion, etc.), while face is robust to the factors that may affect gait (walking surface, clothing, etc.). We review several most recent face and gait fusion methods with different strategies, and the significant performance gains suggest these two modality are complementary for human identification at a distance.

متن کاملPeople Re-identification in Non-overlapping Field-of-views using Cumulative Brightness Transform Function and Body Segments in Different Color Spaces
Non-overlapping field-of-view (FOV) cameras are used in surveillance system to cover a wider area. Tracking in such systems is generally performed in two distinct steps. In the first step, people are identified and tracked in the FOV of a single camera. In the second step, re-identification of the people is carried out to track them in the whole area under surveillance. Various conventional fea...
متن کاملDynamic Biometrics Fusion at Feature Level for Video-Based Human Recognition
This paper proposes a novel human recognition method in video, which combines human face and gait traits using a dynamic multi-modal biometrics fusion scheme. The Fisherface approach is adopted to extract face features, while for gait features, Locality Preserving Projection (LPP) is used to achieve low-dimensional manifold embedding of the temporal silhouette data derived from image sequences....
