I am looking for a way to detect and crop a image in scan I am receiving. The picture is a form that gets scanned as a result it also contains the white background of scan cover.
Any suggestions how I could do that automatically?

There is an algorithm (with examples) for use in just this scanning situation:
https://github.com/rajbot/autocrop
It is not c# but it should be simple to migrate much of it without significant difficulty.
There is also a simpler algorithm which may fit your needs written in VB for .net here:
