Fifth, Applying the main idea of the improved center weighted median filter to the design of the optimal stack filter based on omnidirectional structural elements constrains, the dissertation raises a kind of improved filter algorithm for de-noising of pulse noise. The theory analysis and the simulation experiment of the image processing shows that this kind of filter can not only remove noise effectively but also keep detail of the image sufficiently.
