A new kind of adaptive weighted median filter algorithm
Aimed at the excellence and shortcoming of the standard median filtering algorithm and the adaptive median filtering algorithm as well as center weighted median filtering algorithm, a new adaptive weighted median filtering algorithm is proposed in this paper. The new algorithm first takes a decision whether the pixel under test is noise or not by comparing the block uniformity of the 3x3 window with one of the entire image, then adjusts the size of filtering window adaptively according to the number of noise points in the window. Finally the noise is removed by means of ameliorated median filtering algorithm. Experimental results clearly indicate that the proposed method has a better filtering effect than the existing methods such as standard median filter, adaptive median filter in terms of visual quality and quantitative measures.
