- Abstract:
-
An adaptive noise filtering algorithm was developed that uses impulse width and noise model detection. With this method, we determine the types and sizes of the windows of the noise filter by the impulse widths and their distribution densities, so that composite noise can be effectively removed from images and the detail of the image can be preserved. The algorithm has been tested with several images. Experimental results indicate that the proposed algorithm is easy to use and the output image quality of the proposed algorithm is superior to that of commonly used noise filters.
