Abstract: Face image location algorithm using Hausdorff distance is part of preprocessing of a motion face recognition system. Combined with the whole recognition system, the algorithm can reduce the error rate. Faces, which are captured from image in moving face sequence, are not always in the same size. The difference can affect the relationship among the face sequences. In this paper, Hausdorff distance is introduced and used as the measurement of face location. When face contour is detected, some side effect information should be filtered. It helps to simplify the successive recognition task.
