Comprehensive Face Location Algorithm Based on Composite Skin Color

In order to solve the slowly processing speed, low precision problems in the Face location and detection, the comprehensive face location algorithm based on composite skin color was proposed in this paper. The YCrCb model algorithm and HSV model algorithm are skillfully applied to the comprehensive face location algorithm. The human body region and background region can be detected and judged by the color value of every pixel for image in the YCrCb and HSV space. Then, the connecting region can be screened and decided by the geometric features of human face, and the face can be accurately located and detected. The experimental results confirm that the algorithm can achieve the accuracy ratio of face location in three cases, such as simple, medium and complexity, are 99%, 92% and 85%, respectively. Furthermore, the accuracy ratio of face location and detection speed was improved in this algorithm.
