| 摘 要： | 针对混有高斯噪声和椒盐噪声的数字图像去噪,提出一种混合噪声滤波算法.首先判断滤波窗中心像素是否是噪声点,如果是噪声点,则取窗口内与其他像素灰度差值绝对值和最小的那个像素值作为噪声点的灰度值;否则,不改变当前像素值.通过实验分析比较,该算法能够在去除噪声的同时更大限度地保留图像的细节信息,并且由于算法在时域内进行,其运算...

| Abstract: | In this paper,a mixture noise filter method is proposed for images corrupted by Gaussian noise and salt-pepper noise.Firstly,if the current pixel is corrupted by noises,replace it with the value of the pixel that has a minimal absolute value in a specifical window;if not,retain it.The experimental results show that the proposed method can effectively preserve the image details and reduce image blurring while removing mixed noise.Thanks to time-domain algorithm,the method is easy to implement and has a less ... |
