Directional motion-compensated spatio-temporal fuzzy filtering for quality enhancement of compressed video sequences
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-frame pixels to reduce both spatial and temporal artifacts. The MCSTF is adaptive to the pixel location, the intensity and position of surrounding pixels. To evaluate the ickering artifacts, a new metric is proposed to take into account the tracking characteristic of human eyes. Simulations on H.264 compressed videos show improvement in artifact reduction of the proposed directional fuzzy lter over other conventional spatial or temporal ltering approaches.
