Abstract :
This work presents an implementation of a postfiltering algorithm for the reduction of video coding artifacts in highly compressed video, based on a fuzzy filtering approach. The implementation considers two fast methods for obtaining the filter weights, which are incorporated into a practical scheme for calculating the filter output.
