Abstract:

In order to solve the problem of eye tracking, we put forward a fast real-time algorithm of eye tracking based on video image. Firstly,convert RGB color space to YCbCr space, and locate human faces by skin color model. After clipping, use Sobel operator edge detection algorithm in convolution processing, and then find the approximate location of eyes through horizontal gray-level projection to determine rough location of the eyes. Divide this area into left and right eye areas with the help of gray-scale projection,then respectively locate the left and right eye, finally get the precise localization of human eyes. Based on the algorithm, we got the results based on video sequence.

Key words: skin color model, Sobel operator, gray-level projection, video sequence
