摘要:
 传统图像分割方法中基于边缘的水平集图像分割对纹理丰富的自然图像存在过分割和欠分割现象。自然图像含有丰富纹理，为了抑制纹理对图像分割的影响，文中结合ROF的保边模型和Y. Meyer的保纹理模型，将图像分解为卡通分量与纹理分量之和，根据纹理的像素变化特性将其表示为一个函数梯度的散度，建立了保边卡通提取的数学模型。结合对象轮廓与卡通分量边缘之间的关系，运用固定点迭代算法提取图像的卡通分量，并对卡通分量运用基于水平集的曲线演化实现自然图像分割。实验结果表明：该算法提取的卡通分量继承传统全变分算法优点，实现了纹理区域近似常数表示，模糊了对象内部的弱边缘，保护了对象轮廓，在一定程度上抑制了纹理对图像分割的影响。
Abstract:
 The traditional edge based level set image segmentation may be over- or under segmentation for nature scene,rich in texture. To suppress the texture on the influence of the image segmentation,propose a new model for natural image segmentation,which follows results of R. O. F. edge-preserving model and Y. Meyer texture-preserving model,using it to extract images to cartoon component and texture component. According to the pixel variation characteristics of texture in the spatial domain,express texture as the divergence of function gradient and build a new cartoon-extracting model in the image domain. In addition,design diverse equation for the model by fixed point iteration algorithm,and the convergence condition by the relationship between the contour of the object and the edge of car-toon component. The experimental results show that the cartoon component extraction algorithm inherits the advantages of traditional total variation algorithm,implementing the approximated constant expression for the texture region,retaining the object contour,bluring weak edges inside the object,to a certain extent,suppressing the effect of texture on segmentation algorithm.
