More and more attention has been paid to the study of moving object segmentation in MPEG compressed domain these years. In this paper, a straightforward scheme by using motion vectors and DCT coefficients is put forward for segmenting moving object in MPEG compressed domain. The feature vector of DCT is defined. As regards local motion scene, the scheme produces a better result of segmentation than 1currently adopted ones. Firstly, the motion vectors are processed by accumulation and median filter; then the areas of non-zero motion vectors are rectified by correlations of DCT blocks to get high-quality segmentation.
