Gabor wavelet-based eyes and mouth detection algorithm

A Gabor wavelet-based eyes and mouth detection system is presented. To extract the potential feature points in face organs, this approach combines the skin color model, grayscale gradient clue and motion model. And then the position-pair of highest likelihood, which is determined from a set of rules, is taken into account. We can verify all of the probable eyes-pairs by Gabor wavelet and support vector machine (SVM) as well. Finally, the position of mouth has been detected according to the position of eyes. The result of experiment shows, the proposed system provided higher right detection rate of fight eyes and mouth. In addition, the performance of system can be improved by further learning.
