Abstract :
The gray-white decision network is introduced as an application of an on-center, off-surround recurrent cooperative/competitive network for segmentation of magnetic resonance imaging brain images. The three-layer dynamical system relaxes into a solution where each pixel is labeled as either gray matter, white matter, or `other´ matter by using raw input intensity, edge information, and neighbor interactions. This network is presented as an example of applying a recurrent cooperative/competitive field to a problem with multiple conflicting constraints. Simulations are presented and discussed
