Abstract

Path analysis becomes a powerful tool when dealing with behavior analysis, i. e., detecting abnormal movements. In a multiple target scenario it is complicated to obtain each object path because of collision events, such as grouping and splitting targets, and occlusions, both total or partial. In this work, a method to obtain the similarity between different trajectories is presented, based in register techniques. In addition, an hierarchical architecture is used to obtain the corresponding paths of the objects in a scene, to cope with collision events. Experimental results show promising results in path analysis, enabling it to establish thresholds to abnormal path detection.
