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

Is there any function in OpenCV or Emgu CV desktop capture options? (addons, libs, classes) So I kn开发者_运维百科ow we can capture camera in a very easy way, is there any option for desktop capturing that way?

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!

This solution is also one outside of emgucv: you can also use the c sharp System.Drawing.Graphics.CopyFromScreen

Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics graphics = Graphics.FromImage(bitmap as Image);
graphics.CopyFromScreen(0, 0, 0, 0, bitmap.Size);
