Abstract: A face recognition method for dealing with salt and pepper noise pollution using Simplified Pulse Coupled Neural Network (S-PCNN) was proposed.Firstly the paper uses similar group of S-PCNN neurons issuing synchronous pulses to detect noise of the original image,and then combines with mathematical morphology to achieve elimination noise point,finally adopts the oscillation time sequences (OTS) of S-PCNN and Euclidean distance to process face recognition.Computer simulation results show that the proposed algorithm is effective.
