An Image Denoising Algorithm Based on Median Filter
Xichang Wang · Computer and Modernization · 2011
As a result of the interference of noise,the results of the following processing will be affected.Hence,before dealing with other image processing,this paper first denoises the image.The conventional medial filters do not perform well in case of uniformly distributed salt pepper noise,so a new adaptive median filter is presented.By comparing SNR,PSNR and visual effects of the denoised image,it showes that comparing with the conventional median filter the new filter performs better in removing the noise and reducing distortion in the image.
