Based on a convex total variation (TV) variational energy function
this paper proposes a wavelet based variational 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.
