OpenCV4 DNN人脸检测

此文源于在opencv学堂上看到的一篇文章，自己尝试了下，

首先安装opencv4，在OpenCV的sourcessamplesdnnface_detector目录下，有一个download_weights.py脚本文件，首先运行一下，下载模型文件。下载的模型文件分别为：

Caffe模型

• res10_300x300_ssd_iter_140000_fp16.caffemodel

• deploy.prototxt

tensorflow模型

• opencv_face_detector_uint8.pb

• opencv_face_detector.pbtxt

下面为自己在visual sutio2019中的测试代码，

复制代码#include <opencv2/dnn.hpp> #include <opencv2/opencv.hpp> using namespace cv; using namespace cv::dnn; #include <iostream> #include <cstdlib> using namespace std; const size_t inWidth = 300; const size_t inHeight = 300; const double inScaleFactor = 1.0; const Scalar meanVal(104.0, 177.0,

const size_t inWidth = 300;

const double inScaleFactor = 1.0;
const Scalar meanVal(104.0, 177.0,
