摘要
为了抑制医学图像上的椒盐噪声等污染,并尽量保持图像的清晰度和细节边缘信息,提出了一种利用优化的自适应中值滤波器来滤除医学图像中椒盐噪声的新方法。该方法克服了自适应中值滤波不能有效剔除掉尖锐椒盐噪声点的不足。实验表明,该方法可以有效滤除医学图像椒盐噪声。
In order to reduce the interference of salt and pepper noise in the medicine images and keep the definition of image and detail edge information,a new method of eliminating the salt and pepper noise in medicine image based on the optimization adaptive median filter is presented in the paper.The method can overcome the shortage of low-efficiently of adaptive median filter in eliminating the sharp salt and pepper noise point,when the probability of salt and pepper noise is high.Experiments show that the metho...
