In this paper, an unsupervised texture image segmentation method based on active contour is presented. Gabor filters and the anisotropic diffusion method are combined to obtain the texture feature for segmentation. A small set of Gabor filters are used to extract scale and orientation properties of the texture, and original image is also included as a feature channel for the intensity informat ion of the texture. If the diffusion function based on total variation is chosen, vector anisotropic diffusion can smooth the details away with the region border reserved in every channel. Finally the geometric MDL active contour image segmentation algorithm is expanded to vector-value data to segment the features vectors. Experiments on various kinds of texture images show that the method is effective.
