How to capture each frame of a USB webcam using VB.net?

While I have got some leads from an older SO post and from this site, I haven't been able to figure out how to capture each f开发者_开发技巧rame of a web-cam.

What I would like to do is something like this capture a frame then do some image processing on it and display the output and then move on to the next frame.

Can I can access to web-cam frame events or is there any efficient way to achieve this?

Sounds like the perfect job for OpenCV or AForge image processing.
