Adaptive shrinkage de-noising using neighbourhood characteristic
W. Shengqian, Z. Yuanhua, Z. Daowen · Electronics Letters · 2002
A new adaptive shrinkage de-noising algorithm for images based on the neighbourhood characteristics is presented. This algorithm determines the shrinkage thresholds according to the neighbouring coefficients and the noise level. The experimental results show a great improvement with respect to the standard wavelet shrinkage algorithms.
