New Adaptive Mixed Filter for Image Denoising
Chunfang Shao · Modern Electronics Technique · 2009
In this paper,a new adaptive mixed filter is investigated for noise removal of an image contaminated by Guass noise and impulse noise.In the process of removing pepper noise,this method can enlarge filter window size adaptively.While in the process of removing Gauss noise,it can choose the threshold adaptively.Computer simulation results validate that the denoising ability of this method is better than the traditional mean filtering method,median filtering method,wavelet hard threshold method and wavelet soft threshold method by its higher Signal to Noise Rate(SNR) and smaller minimizes the Mean Squared Error(MSE).The eminent performance of this method is also proved that it has better details preservation capacity.
