“…In order to accurately and promptly detect potential safety hazard, a modified background model based on Dempster-Shafer theory, and a passenger flow status recognition algorithm based on features of image connected domain were proposed to improve the accuracy and real-time performance of passenger flow detection [2]. For the challenging of abrupt illumination, occlusions, out of field of view, and cluttered backgrounds, a novel tracking framework was developed, which consists of two steps: image shadow removal and tracking by association [3]. A sparse representation based approach is proposed for pedestrian detection from thermal images.…”
