Abstract

In this paper, we present a segmentation-based block matching algorithm for video compression. First, the decoded frame is segmented into background and foreground using a two-step predictive procedure. This segmentation is then used in estimating the motion in the next frame. Being a backward procedure, the segmentation information is not transmitted to the receiver. Experimental results show that blocks at the leading edges of moving objects get better compensated with improved subjective quality of the motion compensated frame.
