Edge-region integration for segmentation of MR images

A data-driven segmentation scheme is described that integrates edges and smooth regions. Edges are detected first and then used to guide the action of a dualresolution agglomeratine •parametric region detector. The scheme is applied to a variety of MR images. A comparison is made of segmentations produced by the scheme and by medical experts. The results are better than those obtained from the edge detection process alone.
