On http://azzlsoft.com/tag/histogram-equalization/ link

for (int pixelIndex = 0;
pixelIndex < grayscale.Pixels.Length;
pixelIndex++)
{
byte intensity = (byte)(grayscale.Pixels[pixelIndex] & 0xFF) ;
histogramData[intensity]++;
}
I am not getting the intensity value as writablebitmap grayscale not finding .Pixels[pixelIndex] methode

I managed to get the histogram by referring the following link
http://trompelecode.com/blog/2012/04/how-to-create-an-image-histogram-using-csharp-and-wpf/

I drawn input histogram and output histogram i.e after performing the image enhancement operations
Now I want to plot curve showing the difference in original image pixel and change in pixel after adjustments like image enhancement operations...

On which parameters the frequency is defined/decided or we take the frequency randomly??
I just gone through the follw link
http://azzlsoft.com/tag/histogram-equalization/

But I am not getting grayscale.Pixels[pixelIndex] so cant getting the intensity
