For a project, I have to detect a cube with a webcam. I think that OpenCV could be a good solution to find out where is it (real-time). I'm new in the computer vision domain, and I wonder which algo can I use ? Hough ? I've seen this video (quite impressive!): http://www.youtube.com/watch?v=ytvO2dijZ7A Do you know how he was able to do it ?
Thank you a lot for your help
