Research on Image Filtering Algorithm

Analyzes the denoising algorithm based on salt,pepper noise and gaussian noise.These algorithms have median filtering,average filter and Wiener filter.The experimental results show that the median filtering has better effect for salt and pepper noise.Compared with median filtering and average filter,the Wiener filter has the better effect for the Gaussian noising.However,the Wiener filter algorithm is easy to loss of edge information and almost invalidly to salt and pepper noise.
