A Study on Denoising Method for Image of Mixed Noise
Xiaofeng Zhao, Hongsheng Xie · International Journal of Multimedia and Ubiquitous Engineering · 2014
In view of the images polluted by mixed noise in actual image processing, in this paper, the hybrid filter algorithm combined by median filtering and wavelet transform is generalized to two-dimensional fractional wavelet domain, verified the effectiveness and advantages of hybrid filtering algorithm combined by median filtering and twodimensional fractional wavelet transform.And put forward a method to calculate the optimal fractional order in the case of unknown noise, eventually get better image denoising effect and has certain actual application value.
