| Abstract(in English) | In this paper, we proposed a robust segmentation method for MR images with noise by using region information. The feature vector is extracted from a 3x3 region. Compared with the conventional pixel-based method, the proposed region-based method is tolerant and robust to the noise, but the dimensionality of the feature vector is much larger than that of the conventional method. We also propose to use principle component analysis (PCA) as a preprocessing to reduce the large dimensionality. The experimental results show that the proposed method is superior to the conventional method with the same dimensionality of feature vector. In addition, the algorithm of K-means is used for un-supervised clustering. |
