noise while avoiding blurring of image detail, the first progressive reflected in each iteration detection process are carried out on the results of the last test for a high rate of contamination color image, through this iterative process can be gradually distributed more densely noise eleven ...
In this paper, a novel technique is presented for removing salt and pepper noise from a true color image. This technique is based on simple trigonometrical formulas of general triangle so it is named as triangular analysis of true color image.Rajat Dangi...

I found a matlab code to remove salt and pepper noise from a color image written byImage analystinhere. I have two question regarding to the code. 1. How to skip the first and last column and row of the image from median filter?
椒盐噪声是指两种噪声,一种是盐噪声(salt noise)盐 = 白色(255),另一种是胡椒噪声(pepper noise)椒 = 黑色(0)。前者是高灰度噪声,后者属于低灰度噪声。一般两种噪声同时出现,呈现在图像上就是黑白杂点。 对于彩色图像,也有可能表现为在单个像素BGR三个通道同时随机出现的255或0,也是模拟的原理。
Most of these standard median filters have been established as a reliable method to remove salt-and-pepper noise without damaging the edge details. However, the major drawback of standard median filter is that the filter is only effective to work at low noise densities. This is due to the ...
