How to change position of "Contour" OpenCV

lxnr_p

Hi everybody, I'm using the opencv findcontour library that I modified to use with the webcam, that works great, but I would the webcam be in the center of my window. When I change the values of : image(video, x, y); it only move the video of the webcam, and not the contours. It stay on the top left. Here my code :

Thanks for your help :)
