【摘要】 为提高人脸检测效率,研究实现采用肤色模型的低分辨率视频快速人脸检测算法。主要步骤包括采用Gray World方法的图像预处理、图像二值化和形态学处理等,从而实现快速人脸定位。实验结果证明该方法的正确性、快速性和有效性,该算法可以为后期人脸特征检测的精确定位奠定基础。更多还原

【Abstract】 For the purpose of improving the efficiency of the human face detection, proposes a skin color model based algorithm to fast detect human face in low resolution video. The main steps include image pre-processing using Gray World method, image binaryzation and morphological image processing, and the algorithm enables fast face detection. Tests show the method is correct, fast and effective, it can lay the foundation for precise positioning late facial feature detection.更多还原
