Is there any function in OpenCV or Emgu CV desktop capture options? (addons, libs, classes)

Question

Is there any function in OpenCV or Emgu CV desktop capture options? (addons, libs, classes) So I know we can capture camera in a very easy way, is there any option for desktop capturing that way?

Answer 1

I would recommend doing a screen capture outside of Emgu (ie, in non-Emgu C++/C#).

The first step is to create a bitmap from the screen image. There are plenty of websites detailing methods of how to do this. I found this one helpful.

Once you have a bitmap, it's easy to create new Emgu Image<,> from it. Here's the documentation for that.

Good luck, and have fun!
