Facial Feature Addition and Alteration

While face and facial feature detection is an important and popular problem in image processing and algorithm development, the work presented here is far less important. Here I attempt to build on existing methods of face detection and facial feature detection in order to automate and customize an old practical joke where one scribbles facial hair onto a picture of friends, celebrities, or even complete strangers. Using the OpenCV Viola-Jones Face Detection algorithm and a modified chin and cheek contour detection method, key locations on the face are defined for use in drawing photorealistic facial hair on an image. A skin detection algorithm is also used in order to segment out and remove real facial hair and replace it with photorealistic skin.
