Automatic face and facial features initialization for robust and accurate tracking

Face detection and tracking, through image sequences, are primary steps in many applications such as video surveillance, human computer interface, and expression analysis. Many currently existing techniques don’t perform well due to pose variations, appearance changes, illumination changes, complex backgrounds, and inaccurate initialization. The last short coming, which is the difficulty to initialize motion regions, is a problem facing any tracker. In this paper, we present an automatic and robust face detection and tracking system for color image sequences. Face detection is done using skin color segmentation and connected components analysis. Later, facial features are detected by active shape models and a face mesh is initialized. Finally, the tracking is done by active appearance models. Experimental detection and tracking results on a pose varying face video are given.
