Face detection for image annotation
The problem of face detection in images  locating image areas corresponding to human faces  has received a considerable amount of attention in recent years due to numerous possible applications. In this paper, we describe a face detection system for an image annotation task that requires detection of faces at multiple scales against a complex background. The proposed system is a top-down system; it uses the presence of skin tone pixels coupled with shape and face-specific features to locate faces in images. The main distinguishing feature of the proposed system is its use of an iterative region partitioning procedure to generate candidate face regions. To date, the performance of the system has been tested with over 200 test images of varying complexity with promising results.
