Moving object segmentation and tracking in video is an important task not only in computer motion detection and tracking, but also in MPEG-4. A new moving object segmentation and tracking method based on the improved PCA is presented in this paper. Firstly, the improved PCA is used to segment the moving object in the original image sequence. In this step, three frames are enough for the segmentation of rigid and non-rigid moving object from background. Secondly, tracking is performed by shifting the 3 frame window along the image sequence and repeating the first step in each window.
