The Grey-White Decision Network (GWDN) is presented as an analog constraint satisfaction neural network that segments magnetic resonance brain images. Constraints on signal intensity, neighborhood interactions and edge influences are combined to assign labels of grey matter, white matter or “other” to each pixel. An improved version of this novel segmentation network that is provably stable is described. Results of the network are presented along with a comparison of these results to a collection of human segmentations. The network is discussed in relation to other methods for segmentation and the network’s extendibility is described.
