Blocking artefact removal based on frequency analysis
ELECTRONICS LETTERS 26th November 1998 Vol. 34 No.24，-0001，（）：
An adaptive filtering algorithm for artefact removal in block coded images is presented. Based on an analysis of block artefacts in the frequency domain, the edge image is notch filtered and then used for a neighbourhood analysis. A space-variant filter is applied to the coded image adaptively, dependent on a frequency analysis.
