去除乘性噪声的小波变分模型
Wavelet Based Variational Model to Remove Multiplicative Noise
摘要
Abstract
Based on a convex total variation (TV) variational energy function, this paper proposes a wavelet based variation-al model to remove multiplicative noise.Using convex optimization tool,we give an alternating split Bregman algorithm to solve the proposed model.Compared with existing TV based method,the proposed algorithm is simple and can be extended easily.Numerical experiments are presented to demonstrate the efficient performance of the proposed algorithm and its extensions.关键词
