Paper Abstract

DCT based compression engines1,2 are well known to introduce color artifacts on the processed input frames, in particular for low bit rates. In video standards, like MPEG-23, MPEG-44, H2635, and in still picture standards, like JPEG6,7, blocking and ringing distortions are understood and considered, so different approaches have been developed to reduce these effects8,9,10,11. On the other side, other kinds of phenomenon have not been deeply investigated. Among them, the chromatic color bleeding effects has only recently received proper attention12,13. The scope of this paper is to propose and describe an innovative and powerful algorithm to overcome this kind of color artifacts.
