Detection using Viola-Jones is now on the iPhone. Demonstrating OpenCV's detection using Viola-Jones algorithm based on Haar features. The iPhone shows detection at real time performance! (30 FPS - under specific configurations). Detect frontal face, profile face, eyes or mouth. Play with many parameters of the algorithm. Just hit "Hud" to set the different parameters, and see how the iPhone behaves. A must have for anyone contemplating on using the technology in there app. Great for Augmented Reality... Enjoy!
