An adaptive center weighted vector median filtering for color images is proposed. The relationship between the
filtered pixel and its several nearest neighbor pixels is determined by introducing the projective distance. The link between the
given pixel and the median value of template based on the aggregative distance is considered, and the weighting coefficient
of the given pixel is adaptively obtained. A multi-set of vectors is formed and the median value of the multi-set is taken as
the median of filtering. Experimental results show that the proposed method can effectively remove salt and pepper noises in
a color images and preserve color information and local details.
