Emgucv中的高斯噪声 [英] Gaussian Noise in emgucv

问题描述

如何使用emgucv向图像中添加高斯噪声（具有特定的均值和方差）？

How can I add gaussian noise ( with a particular mean and variance ) to an image using emgucv ?

推荐答案

I'我不确定您作为高斯滤波器的要求是否倾向于消除噪声。要使用自定义内核，可以使用以下代码。如果您希望以设定的均值和方差添加噪声，则可能必须求助于遍历my_image.Data属性并以这种方式添加。这是使用自定义内核的代码，如果不是您所需要的，请告诉我，我将尝试找到更合适的方法，在这种情况下，指向示例图像的链接可能会有用。

I'm not sure quite what your asking as a Gaussian filter tends to be there to remove noise. To use a custom kernel you can use the following code. If you wish to add noise with a set mean and variance then you may have to resort to looping through the my_image.Data property and add it that way. Here is the code for using a custom Kernel if it's not quite what your after let me know and I'll try and find something more appropriate a link to example images may be useful in this case.

Image<Bgr, Byte> my_image = new Image<Bgr, byte>(open.FileName);

float[,] k = { {0, 0, 0},
               {0, 0, -0},
               {0.33F, 0, -0}};

ConvolutionKernelF kernel = new ConvolutionKernelF(k);

Image<Bgr, float> convolutedImage = my_image * kernel;

pictureBox1.Image = convolutedImage.ToBitmap();

我希望这会有所帮助，
