A RECURSIVE ALGORITHM FOR THE REDUCTION OF QUANTIZATION EFFECTS OF IMAGE COMPRESSION

Fabrizio Russo

Abstract

A simple technique for the restoration of color images degraded by lossy compression is presented. The proposed approach deals with the YIQ color space and processes the luminance component by means of a recursive algorithm based on fuzzy models. This design choice combines effectiveness and simplicity. Indeed, the method can satisfactorily reduce quantization errors produced by lossy compression such as the popular JPEG technique. On the other hand, the tuning process is very fast because it requires one parameter only.
