Abstract
A face-tracking method with high accuracy is provided. The face-tracking method includes generating an initial face shape according to the detected face region of an input image and a learned data base, wherein the initial face shape comprises an initial inner shape and an initial outer shape; generating a refined inner shape by refining the initial inner shape according to the input image and the learned data base; and generating a refined outer shape by searching an edge of the refined outer shape from the initial outer shape toward the limit of outer shape.
