The new algorithmfor detection of noise points is based on grayscale distribution of neighboring pixels in different directions, and it uses the improved algorithm of maximum2minimum exclusive median method to estimate the gray levelof current noisypixels. Introducing thefuzzy logic rulesinto the new algorithm , the gray level of noisy pixels will be restored more reasonably. Simulation results show that the new algorithm may bring about better effect in eliminating impulsive noise in comparison with the improved median filter methods.
