Displaying Video from webcam in opencv on GTK+

I'm new to this and was wonderin开发者_如何转开发g what i need to do to my open cv code to display using gtk. Does it need to be converted or what?

It's fairly simple to do using Python. Here is a class that I've written to control a webcam using OpenCV and convert the frames to a NumPy array:

After that, you can use gtk.gdk.pixbuf_new_from_array() to create a pixbuf which you can then create a gtk.Image from. Note that PyGTK needs to be compiled with NumPy support for this to work.

You can also use Matplotlib to display the frame in a GTK user interface. Here's another class that I've written that does that:
