The space incoherent and small changes in the amplitude of input image can be compensated by utilizing the character of PCNN that the similar input neurons can pulse simultaneously. And then the small regions of the image can be segmented very well by means of adjusting a threshold parameter of PCNN, therefore, the complete information of the image can be preserved and the quality of the image can be improved too. It is more effective to enhance the segmentation quality of the image than the method that enhanced an image through the image enhanced function DECORRSTRETCH of MATLAB and carrying out the information of spectral bands which will be normalized, finally adjusting the threshold.
