智能录播系统中站立人脸检测定位的实现

Realization of Detection and Location of Standing Face in IntelligentRecording and Broadcasting System Computer Engineering and Applications

针对智能录播系统中站立检测的现状和需求,提出了一种站立人脸的检测定位算法。算法通过帧差法确定活动区域,然后对活动区域光照补偿、肤色检测初步筛选人脸区域,结合人脸特征以及人脸面积占比等,综合区域划分,实现了站立人脸的检测定位。实验结果表明,该算法具有较高的检测准确率和鲁棒性。

According to the present situation and demand of standing detection in intelligent recording system,a location algorithm for standing face detection is proposed.The algorithm determines the active region by frame difference method.Then preliminary screening the face area by illumination compensation and skin color detection,combined facial features and face area ratio,integrated region partition,realized the detection and location of standing face.It is showed that the proposed algorithm has higher detection accuracy and robustness by experimental results.
