Local characteristic based wavelet shrinkage denoising algorithm
Shengqian Wang, Zhou Yuanhua, Zou Daowen · Electronics Letters · 2002
A new wavelet shrinkage denoising algorithm for an image is presented, which is based on the local characteristic of an image. The proposed algorithm efficiently reduces noise and achieves better peak signal-to-noise ratio than in previous work. It is shown that this method can reduce noise for low SNR images.
