Abstract
A video frame is decomposed into blocks of pixels. Blocks that contain moving edges are not processed further. The remaining blocks are examined for the likelihood of having color bleeding artifacts, and not processed further if the likelihood is low. The likelihood is determined by examining statistics of the chrominance values. The remaining blocks are de-color bleeding filtered at the chrominance plane, without affecting the corresponding luminance plane.
