The invention discloses a salt and pepper noise filtering method based on a color image, relating to the image processing field. In the method, based on a vector median filter for detecting a gradual switch median, a vector median filtering method is utilized to effectively inhibit the pulse ...
Using this function, we will add noise in each color band separately. But is this correct..? While denoising, we have to remove noise from color image or from each plane separately.댓글 수: 0 댓글을 달려면 로그인하십시오....

There is a significant recent advance in filtering of the salt-and-pepper noise for digital images. However, almost all recent schemes for filtering of this type of noise are not taking into an account the shape of objects (in particular edges) in images
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...
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 ...

2) Salt & pepper noise 椒盐噪声 1. However, salt & pepper noise occur during ima ge generation, communication and transformation, and affect image quality. 为了消除图像上的椒盐噪声 ,并尽量保持图像的清晰度 ,提出了一种在中值滤波基础上 ,经过灰度直方图的分析 ,再采用合适的灰度级形态学运算去除图像...
For removing salt and pepper noise from corrupted image we are using so many algorithms. In this paper we propose two phase scheme for removing salt and pepper noise and edge preservation; in the first phase Adaptive median filter is used to detect corrupted pixel and preserving the edges. In...
