Graph-based Object Detection and Tracking in H.264/AVC bitstream for Surveillance Video

H.264/AVC 비트스트림을 활용한 감시 비디오 내의 그래프 기반 객체 검출 및 추적

In this paper we propose a method of detecting moving object in H.264/AVC bitstream by representing the $4{\times}4$ block partition units as nodes of graph. By constructing hierarchical graph by taking into account the relation between nodes and the spatial-temporal relations between graphs in frames, we are able to track small objects, distinguish two occluded objects, and identify objects that move and stop alternatively.
