WebHOG特征提取方法就是将一个image(你要检测的目标): 1)灰度化(将图像看做一个x,y,z(灰度)的三维图像)(必须灰度化); 2)采用Gamma校正法对输入图像进行颜色空间的标准化(归一化);目的是调节图像的对比度,降低图像局部的阴影和光照变化所造成的 … WebApr 19, 2024 · In this tutorial, you will learn how to perform face detection with the dlib library using both HOG + Linear SVM and CNNs. The dlib library is arguably one of the most utilized packages for face recognition. A Python package appropriately named face_recognition wraps dlib’s face recognition functions into a simple, easy to use API.
