提出一种新的椒盐噪声滤除方法.通过对图像二值化,对其进行统计分析确定噪声点.仅改变噪声点的像素值,避免了中道滤波对图像细节的破坏,同时又滤除了噪声.实验结果表明,新方法可以有效去除椒盐噪声,同时很好地保护图像的细节. This paper proposes a new filtering method of salt and pepper noise.After image binarization, statistical analysis is performed to determine the noise point.It is only to change the pixel value of the noise point to avoid the damage to the detail of the image, meanwhile, Noise.Experimental results show that the new method can effectively remove the salt and pepper noise, while well protected the details of the image.
