An iterative filtering algorithm based on signaling game idea

An iterative digital image filtering algorithm based on signaling game idea is presented. Aim at shortages of the standard medium filtering algorithm, this paper provides an improving approach through appointing signaling game idea. The method is that choose filtering window, sort every pixel value in the window and find the median first and then compare the median and the window central pixel value, and obtain the probability that the window central pixel is signal point or noise point according to the similarity between the medium and window central pixel value, finally, construct membership function to fix the value of window central pixel and bring the value amended to the following pixel filtering operation. As the method above, we repeat the operation until all the value of pixels in the image have been amended. The results of computer simulation prove that the improved algorithm not only can suppress the noise but also keep details of the image well.
