Objective: Face Painting to Defeat Face Detection

Now see how face detection can fail when you use face paint.

Equipment

Face Paint
Creative Live!Cam Optia AF

Activity

1.  Apply face paint onto your face.

2.  See what happens with Live!Effects when you try to add glasses.  Is the face recognized at all?  Can you add a hat?  If the head is turned slightly, is the face not recognized?

3.  Take a picture(s) and save to USB drive or folder.

The Live!Cam algorithm can detect the 2^nd, 4^th, and 5^th choices.  For the 1^st and 3^rd choices, the face is not recognized if the head is turned slightly.  The camera may recognize a face with the 3^rd choice, but the location of the eyes will be incorrect.
