摘要
介绍了一种图像去噪的方法 :梯度倒数加权算法。此种算法可以较好地去除图像的噪声同时又能保持图像的细节信息 ,但该算法对椒盐噪声污染的图像平滑效果不理想。基于此种算法我们提出了一种改进的算法 ,事实证明改进的方法既能很好地去除了图像中的椒盐噪声 ,同时又能保持图像的边缘和细节。
A method of eliminating the noise of image is introduced. Grade inverse weight smoothing arithmetic can not only wipe off the noise but also save the detail message.But this method can't smooth away the pepper noise well. Based on the arithmetic, we suggest a improved method which can wipe off the pepper noise excellently and at keep the detail message.
