%X 在YIQ和YCbCr色彩空间中,结合人类面部矩形的特征,提出了一种用于人脸检测和定位的算法.该算法通过比较输入图像R、G、B3通道总的平均值和B通道的平均值来选择色彩空间,并采用基于积分图的2维OSTU法进行肤色分割；然后根据肤色区域面积对肤色分割图像进行中值滤波；最后根据中值滤波后的肤色分割图中的肤色区域面积构造最佳人脸矩形,并用该矩形去定位人脸区域.实验结果表明:该算法较传统的采用单一色彩空间的人脸检测算法具有更高的准确率.<br>An algorithm for face detection and location based on human facial rectangular characteristics in the YIQ and the YCbCr color space has been proposed.The algorithm selects the color space by comparing the average of the input image channels of R,G and B with the average of the channel of B,and segments the skin area with the two-dimensional OSTU and integral figure.Then,the skin segmentation figure by median filter based on the acreage of the skin area has been processed.In the end,an optimal face region rectangle with the acreage of the skin area which has been processed by median filter has been constructed,and the rectangle to locate the face region has been used.The experiments show that the algorithm has higher accuracy than the traditional face detection algorithms using single color spac
