| 摘 要： | Luminita A.Vese和Stanley J.Osher基于总变差最小化及Yves Meyer提出的振荡函数空间理论提出了卡通—纹理分解模型,在Vese和Osher的分解模型中参数选择为恒定值。本文提出了自适应参数的卡通—纹理分解方法,该方法是根据图像梯度的变化自适应地选取参数,能有效保护卡通图像的边缘,从而更好地提取纹理特征。

| Abstract: | Based on the variation minimization model of Rudin,Osher and Fatami for image restoration and the theory of oscillatory function spaces introduced by Meyer to model texture or noise,Luminita A.Vese and Stanley J.Osher proposed a model for decomposing a given image into a cartoon and an oscillatory component.In the Vese and Osher decomposition model,the parameters are given constants.An adaptive image decomposing approach that selecting the most appropriate parameters adaptively based on the gradient information of each pixel is proposed.Numerical experiments show that the proposed method can preserve sharp boundaries of cartoon while extracting textures adequately. |
