QuestionHow Can I set Noise In Image ? Pin

Hello Friends
I am creating a MFC application in which I am saving a image from DC into bmp.I gave different effects on that image by using Gaussian Filter Formula by following this link
http://lodev.org/cgtutor/filtering.html[^]

I am setting image blur,embossed and etc by getting image pixels and then settign back.
Now, I want to add noise Effect to image based on some range(0-100)[if 10 then less particles in image,if 20 more particles and so on].

Using same Gaussian,I didnt get any idea to use any filter to give effect of Noise.

I tried my own formula also but it is not adding random particles to image.
Here is own way to set noise.I got pixels of Image and randomly change some pixels to black but tht was not producing noise in some continuous manner. I want it should apply in some manner.
C++
int n = 0;
for(int x = 0; x < nWidth; ++x)
{
   for(int y = 0; y < nHeight; ++y)
   {
       n++;
      if(n > 9 + randomFactor)
      {
           n =0;
           randomFactor += x;   //Added Randomly
           memDC.SetPixel(x,y,RGB(0,0,0));
      }      
   }
}


I want to add noise randomly but in some continuous manner.
Any Ideas??
Regards
Y
