摘要：
In order to overcome the disadvantage of total variation (TV) method, this paper presents a local structure adaptive (LSA) TV model based on a discontinuity indicator for image restoration. The proposed method first presents a discontinuity indicator based on the eigenvalues of the structure tensor, and then p norm is adaptively selected based on the proposed discontinuity indicator. Experimental results show that the proposed method can effectively preserve edge information during noise removal and its superiority to the state-of-the-art methods. (C) 2012 Elsevier B.V.
