Abstract

In this paper, a multichannel edge enhancing filter (MEEF) applied to color image processing is proposed to improve the degraded edges in color TV picture which are classified as the following cases: the blurred edges caused by unfocusing or fast shift of camera, the serrated edges caused by interlaced scanning, and the chroma-cross edges caused by channel dispersion Because of a high between-channel dependence in color image, individual edge enhancement in each channel is not a natural method without utilizing between-channel dependence. Thus, this technique is not recommended in color image processing. The proposed MEEF is successfully used in dealing with this sort of the degraded edges of multichannel image. The root signals and edge enhancement properties of MEEF are investigated in detail. The experimental results show that MEEF outperforms independent edge enhancing filter in improving the degraded edges caused by unfocusing, interlaced scanning and channel dispersion.
