Some code issues if you want to use this with OpenCV 3.0

Imgproc.rectangle no longer Core.rectangle

highgui is gone, so:

import
import static

Cheers!

that's you Taha Emara!! that's good!!

[danpogangeanu]

The code works perfect with a regular webcam. Thank you! for a handy-cam I get a error "buffer sizes do not match". If can provide the additional implementation before i dig it, I would appreciate.
Thank you so much again!
