Yang, Zhaoxia; Lu, Feng; Tian, Qianqian Variational method with two adaptive regularization parameters and its application in noisy image restoration. (Chinese. English summary) Zbl 1085.68733 Acta Sci. Nat. Univ. Sunyatseni 44, No. 4, 20-23, 27 (2005). Summary: In noise removal by the approach of regularization, the regularization parameter is global. A variational model with two adaptive regularization parameters according to the different orientations constructed through the characters of different kinds of pixel in a noisy image, is presented for adaptively noisy image restoration. Morever, a discrete scheme is constructed for a digital image through partial differential equation, which facilitates the computation effectively.
