Face and Eye Location Algorithms for Visual User Interface

초록

Face image processing techniques are essential for advanced human-computer interaction. Most previous face image processing systems have been proposed under the assumption that approximative face regions or the locations of facial features are known. In this paper, we mainly discuss face and eye location algorithms. The proposed techniques use no prior knowledge on the given image. It is less sensitive to backgrounds and lighting conditions than previous approaches. Mosaic image representation and valley representation are adopted for face detection and eye location, respectively. Extensive experiments have been performed, and very encouraging results have been achieved.
