PCNN model is a new generation of artificial neural networks,because of its unique coupling transmission mechanisms,it is now widely used in image processing and data analysis.However,the parameters of the model itself is difficult to be determined,even more the internal mechanism of PCNN have not been well explained in mathematics,making the research and application of PCNN be greatly limited.in this paper,we studies the phenomenon of auto-wave,while application of automatic wave model to improve the image...
