Abstract

An automatic image segmentation for MR brain images based on the gray level characteristics of the images is developed. The method analyses a sequence ofMR brain images to provide region information as well as boundary data for classification and eventual creation of 3-D models. The system incorporates global information from the image set through an analysis of the statistics of the cooccurrence matrices. Local consistency is then applied with the use of a relaxation algorithm on individual images. The cooccurrence matrices provide conditional probabilities for the classification of pixels into specific regions or boundaries based on the matrix distribution. A constrained stochastic relaxation is then used to refine the probabilistic labels using local image information. Results ofthe technique are presented for MR brain images.
