Abstract. In image denoising process, it is difficult to separate texture from noise. In order to separate them, we should know their different characteristics, or we can use some metrics (such as norms) to distinguish them. In this paper, we propose a new model which decomposes an initial image  f into three component: structure part  u , texture part  v , and noise part  w . And we use the H−1 norm which is investigated in the work of Aujol and Chamboll to separate texture from noise.

Keywords: metric, total variation, Sobolev space, H−1norm, texture, dual transform
