Luminita A.Vese and Stanley J.Osher proposed a model for decomposing a given image into a cartoon and an oscillatory component,witch based on total variation minimization.By using the method of halfquadratic regularization in the model of Vese and Osher,this paper proposes a model that combines extracting texture with detecting contour.Finally,numerical experiments show that the proposed method can decompose a given image into a cartoon and an oscillatory component better while detecting contour well and truely.
