Based on the model that combines image decomposition with contour detection,it is put forward an adaptive method that select the most appropriate parameters adaptively according to the image feature in different positions of the original image.Based on the results of the pre-analysis of original image,different parameters are selected respectively in the edge,texture,piecewise smooth area.That achieves the full extraction of texture,guarantees cartoon image smoothness while protecting the edges of the objective.Numerical experiments show that the proposed method improves the contour detection accuracy,reduces the singularity and makes the cartoon-texture decomposition more thoroughly.
