Study of moving-object segmentation in DCT-based compressed video = 이산여현변환으로 압축된 동영상에서 움직이는 물체의 분할에 관한 연구

A block-based automatic segmentation algorithm has been developed for detecting and tracking moving objects in DCT-based compressed video. The proposed algorithm segments moving objects with block resolution using the stochastic behaviour of the image blocks in the DCT domain.
