OpenCV3.3.1的人脸识别API相较于之前版本有些变动 原3.2以前的是createEngenFaceRecognize() 现更改为EigenFaceRecognize::create() 其他几个创建函数也做了如上改变。 包含头文件#include< face/face.hpp > 命名空间using namespace cv::face; 然后我又无聊的在某宝搜了下与OpenCV相关的书籍,结果发现近期有很多新...
train(images, labels); // 假设imageToRecognize是待识别的人脸图像 int predictedLabel = recognizer.predict(imageToRecognize); 这里,images是包含多个人脸图像的Mat数组,labels是对应图像的标签。 实战建议 优化性能:在移动设备上,性能优化至关重要。考虑使用更轻量级的算法或优化图像处理流程。 增强鲁棒性:在不同...

Before we can recognize faces, we need to train the recognizer on a dataset of images. Here’s how to train the recognizer using LBPH in OpenCV: importcv2importosimportnumpyasnp# Initialize the LBPH recognizerrecognizer=cv2.face.LBPHFaceRecognizer_create()# Prepare the datasetdata_path='./data...
