Recent research in neuroscience has proposed a new artificial neural networks model,the pulse coupled neural networks,PCNN.Several PCNN structures for image processing have been proposed depending on the model's potential.In the research of the theories and the applications of PCNN,it isn't a trivial task to define the relative parameters properly,and people usually get the values by experience with many experiments.As a contribution to this research field,this paper presents a new method for image processi...
