Abstract
In last years, different types of colour artifacts, overall blocking and ringing, have been deeply investigated. In this paper we focus the attention on chromatic color bleeding effects. This phenomenon is evident in DCT based compression engines. In our work we investigate the possibility to implement a color bleeding removal by means of adaptive filtering. Simulation results and visual impacts show the improvement of color fidelity of the proposed post- processing scheme.
