ABSTRACT:
A face detection and tracking system for detecting and tracking a plurality of faces in real time from an input image comprises: a background removing unit which extracts an area having a motion by removing a background image from the input image; a candidate area extracting unit which extracts a candidate area in which a face can be located in the area having a motion by using a skin color probability map generated from a face skin color model and a global probability map a face area determination unit which extracts (ICA) features from a candidate area and determines whether the candidate area is a face area by using a trained SVM classifier; and a face area tracking unit which tracks the face area according to a directional kernel indicating a probability that a face is located in a next frame based on the skin color probability map.
