Color Image Vector Median Filtering Method Based on Superimposed Filter

Filtering is an important link during the whole image processing. Color image vector median filtering method is widely used. To receive better filtering effect,aims at the noise in the color image and some weakpoints of the traditional filtering method. A modified color image vector median filtering method is proposed. The algorithm uses two filters with the help of the advantages of vector median filtering method. The experimental result demonstrates that the algorithm is very simple and it needs less computation. It can remain intrinsic image information while removing noise. It can acquire good filtering effect by superimposed filter.
