摘　　要：在研究和分析各种人脸检测与定位算法的基础上,并以计算简单、速度快、能精确地提取视频序列中的人脸为原则,提出了一种新的基于运动信息与边缘投影函数相结合的视频序列中的人脸检测与定位算法。该算法设计了双阈值Sobel算子进行边缘检测,该算子检测到的图像边缘清晰、细致、噪声少;提出了平方投影函数,该投影函数不但可区分均值相同的区域,而且可区分方差相同的区域。将边缘函数与投影函数结合起来设计的人脸检测与定位算法简单实用。On the basis of study and analysis of prior face detection and location algorithm,a new face detection and location algorithm based on the moving information with the edge projection function of combining the video sequence is proposed. It is to calculate a simple, fast,accurate face as the principle. A two threshold sobel operator is presented in the paper which can detect a thiuner edge and non - sensitive to noise. A square projection function is designed. The function not only can distinguish regions which have a same mean, but also can distinguish regions which have a same variance. The proposed face detection algorithm combined edge image and projection function has the advantages of simple and practicality.
