有没有办法在不使用 viola-jones 算法的情况下用 opencv 检测人脸？
Is there a way to detect a face with opencv without using viola-jones algorithm?

detecting faces using Haar Cascades in OpenCV is to use a Histogram of Oriented Gradients feature detector. HOG-based object detectors can be used for detecting faces, and this is the technique used in some other image processing libraries such as Dlib. A Histogram of Oriented Gradients 特征检测器的替代方法存储图像的局部梯度和梯度方向的二维网格，并将其与在数据集上训练的参考网格进行比较。
