Abstract: The author proposes a textured image segmentation algorithm which is based on multiresolution wavelet and Gaussian mixture models. At first a preceding process is taken in this algorithm. Then, the image is decomposed by wavelet pyramids. All of those lower resultant image and original image are integrated to a feature vector of a pixel. Those pixels are segmented by Gaussian mixture models. Experiment show the algorithm can give a good result.
