How to enhance contrast of images in AForge (like Photoshop's Auto-Constrast)

I want to enhance slightly a contrast of a bitmap, usually I do this by loading the image in Photoshop and using Auto-Contrast or Auto-Tone. The task is to add some contrast (maybe enhance colors) to the light pictures.

How do I do something close to this using AForge? Or maybe there is some other 3rd party library which could be better used.

You probably want to use one of the AForge.NET colour correction filters. For contrast adjustment, the usual technique would be a histogram equalization or normalization.

Examples are in the AForge.NET documentation for histogram equalization and normalization.

If you are open to third party libraries, try OpenCV. Here is an example of adjusting contrast.
