We present a MR image segmentation algorithm based on the conventional Expectation
Maximization (EM) algorithm and the multiresolution analysis of images. Although the EM
algorithm was used in MRI brain segmentation, as well as, image segmentation in general, it
fails to utilize the strong spatial correlation between neighboring pixels. The multiresolution-
based image segmentation techniques, which have emerged as a powerful method for
producing high-quality segmentation of images, are combined here with the EM algorithm to …
