Auto Crop/Trim border of image in C#

Hello everyone,
I'm trying to remove the surrounding color from the scanned image. I've a scanned page of book but it comes with some surrounding color (e.g grey color). I am trying to cut just the book page leaving the surrounding color. So, far I've tried GDI+ and AForge but nothing seems to work accurately.

Is it even possible (or I'm trying in vain) to automate the trim of surrounding color from the scanned image in C#?

Kindly suggest and any working link would be great help.

Regards

What are your objectives here? Why not automating Gimp/Paint.net/Photoshop..?

I wrote a script to take screen shots of running application after every 2 seconds. Now, those screen shots needs to be cropped of the surrounding space within the C# code. I've tried the following link to crop: http://pastebin.com/FADb57fq

but it crops certain images only but not all. I'm not sure what's wrong. Any help would be a boon for me.

Yes, CopyFromScreen (within a C# method/script) method is used to capture the screen. Basically, screen shots are captured while a certain desktop application is running and it's done for the Audit purposes.

I would use some more low-level style programming to copy just the window I want. Here is a C++ sample showing what steps it needs. Here you'll find a C# wrapper for it: Capture a Screen Shot. And here the same in VBA.

Thanks for the link but I'm stuck at the removing the grey color surrounding each screen shot. I've no problem in taking the screen shot. Could you please suggest something to remove the surrounding color from the image?

That's a good idea. Thanks. But in general removing the surrounding colors from the scanned images would be a nice tool to have. Any ideas on that one?

Are we talking about a general approach or have we some boundary constraints?

The general approach would be a creating a histogram to get the color distribution and then get pixel by pixel to the inner to get the edge of the desired window. The histogram may be your mentioned gray colour.

Another approach could be getting the window coordinates and use them to define your cut edges.
