Human Face Location Based on Gradient Distributions
Baojian Zhang, Gao Guohong, Jinna Lv, Zhu Yanli · 2010
In this paper a fast face location method based on gradient distributions is presented. This method can locate face with certain rotation, or light variation or with glasses or beard in the image. It begins with vertical location by use of vertical integral projection on the two-valued image of the original image, and then proceeds with horizontal location according to the distributions of gradient direction. Experiments have proved this method fast and efficient.
