The present invention discloses a system, an apparatus and a method for locating facial landmarks of the face image. The method for locating facial landmarks of a face image comprises retrieving a set of candidate shapes respectively from a predetermined shape region, each of the candidate shapes having labeled facial landmarks; aligning each of the retrieved candidate shape with the face image to obtain corresponding aligned shapes; determining, according to the aligned shapes obtained in a current stage of two or more stages, a sub-region of the shape region to select a set of candidate shapes therefrom to be retrieved at a next stage following the current stage, repeating the retrieving, the aligning and the determining for the stages to locate the facial landmarks of the face image. With the present method and system, the final solution can be prevented from being trapped in local optima due to poor initialization encountered by cascaded regression approaches and the robustness in coping with large pose variations can be improved. |
