Based on the property of Human Vision System(HVS) that human eye's sensitivity to an image varies with different informative regions of the image,Pulse Coupled Neural Network(PCNN) model is modified for image segmentation.The modified PCNN stimulated by an input image has pulse output with multiple pulse values rather than two,according to the local information rate of the input image.This results in segmentation of the image with respect to local information rate delivered by the image.Experiments on imag...
