Python与Face_Detection face_recognition是网上的一个开源库,是GitHub上最主流的人脸识别工具包之一 其实目前这个库已经帮我们解决了人脸定位的问题,查了下文献,了解到的是将图像灰度化染红通过HOG(方向梯度直方图)来定位人脸位置 具体还要去参考一下HOG检测人脸 灰度化-归一化-计算梯度等等,再次我就不赘述了。 face_...

So in your code you were overwriting the current image so I changed the string parameter so that it was possible to take lots of pictures. import numpy as np import cv2 import time #import the cascade for face detection face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml'...

先说下 人脸检测 (face detection) 和 人脸识别 (face recognition) ,前者是达到检测出场景中人脸的目的就可以了,而后者不仅需要检测出人脸,还要和已有人脸数据进行比对,识别出是否在数据库中,或者进行身份标注之类处理,人脸检测和人脸识别两者有时候可能会被理解混淆; ...
