Proper set mask to mean function

[tmbo]

Currently we are replacing every occurrence of 0 in the image with the mean, converting every black pixel to a mean pixel. This obviously also changes the color of pixels that are not part of the mask.

Possible solution:

• get rid of resizing (probably not a good idea anyway). Already crop a properly sized image from the face video.
• draw the ellipse with image independent parameters (we are actually doing that already, but the problem is the resizing of the frames after painting the ellipse). First in black and in the second pass with the mean color
