Texture Preserving Denoising Method Combining Total Variation and Wavelet Shrinkage被引量：2
《Wuhan University Journal of Natural Sciences》2010年第1期31-35,共5页ZHANG Tao,FAN Qibin School of Mathematics and Statistics,Wuhan University,Wuhan 430072,Hubei,China 
Supported by the National High Technology Research and Development Program of China (863 Program) (2008AA12Z201)
In this paper,we propose a new image denoising method that combines total variation（TV） method and wavelet shrinkage. In our method,a noisy image is decomposed into subbands of LL,LH,HL,and HH in wavelet domain. LL ...
