Face location and eye character detection based on monocular vision gaze tracking system

In the paper an face location and eye detection method is proposed based on active infrared source system, which is to solve the problems of pupil threshold segmentation according to from coarse and fine strategy. This method use bright pupil and dark pupil difference scheme. Firstly, we collect a lot of dark images to train classifiers make use of Haar features, boosting them to be a strong classifiers to face location; then potential region of pupil is found based on the knowledge about facial structure; Finally, human eyes location can be precise found.
