OpenCV for Face Detection Tutorial In this section, we will learn to apply a popular face detection approach called Haar Cascade for face detection using OpenCV and Python. Run and edit the code from this tutorial onlineRun code Intro to Haar Cascade Classifiers This method was first introduced ...

前段时间使用OpenCV的库函数实现了人脸检测和人脸识别,笔者的实验环境为VS2010+OpenCV2.4.4,OpenCV的环境配置网上有很多,不再赘述。检测的代码网上很多,记不清楚从哪儿copy的了,识别的代码是从OpenCV官网上找到的:http://docs.opencv.org/trunk/modules/contrib/doc/facerec/facerec_api.html ...
