In the process of image forming and transmission, image is inevitably polluted by noise which will have an adverse impact on image visual effect and subsequent processing, even directly affect the follow-up image processing results. In actual applications, image usually is polluted by mixture-noise that is composed of different kinds of noise, rather than a kind of noise. So mixed-noise filtering of image is of great significance.
Pulse coupled neural network (PCNN) is a new kind of neural network model...
