Abstract: Pulse coupled neural network(PCNN)is widely used in image processing,pattern recognition and other fields.This paper presented an improved algorithm for foveation points detection based on PCNN.First,neuron excitation function is improved,and wavelet shrinkage method is applied in the image to reduce the noise,preserving the hie-rarchy of image.Then the handwriting is identified through the foveation points detection.The experimental results indicate that the method can effectively improve the recognition rate of handwritten letters.Especially in the noise environment,the recognition rate can be greatly improved.

Key words: PCNN,Foveation points detection,Wavelet shrinkage,Handwriting recognition
