摘要 脉冲耦合神经网络(PCNN)以其更接近生物处理信息机制的优越性,广泛应用于图像处理的各个方面。为了有效的滤除图像中的脉冲噪声,提出来一种PCNN与保持边缘的方法相结合的算法,在滤除噪声后进行图像边缘提取。实验结果表明该算法比中值滤波去噪后提取边缘的算法取得较好的效果。 Pulse coupled neural network(PCNN) is widely use in aspects of image processing for its advantages of information treatment system closer to biological.In order to filter out impulse noise in image effectively,a method of combination PCNN and maintain the edge is proposed,then extract the edge of the image.Experimental results show that the combination algorithm gets the better result than the median filter.
