We propose a directional fuzzy lter to enhance the quality of compressed video sequences. A motion compensated spatiotemporal lter (MCSTF) is applied to intra-frame and inter-fram...

We examine the bit rate variability-distortion (VD) curve of I, P, and B frames of MPEG-4 VBR encoded video sequences. We show that the concave VD curve shape at high compression ...
