Dlib格式与Opencv之间的转化

Mat转matrix

cv::Mat frame = cv::imread("123.jpg");matrix<dlib::rgb_pixel> img;assign_image(img,cv_image<rgb_pixel>(frame));

dlib转mat

cv::Mat img = dlib::toMat(img_gray);

Mat转dlib::cv_image

cv::Mat img = cv::imread("test_image.jpg")  dlib::cv_image<rgb_pixel> dlib_img(img); 

rect转dlib的rect

 dlib::rectangle dlibRect((long)opencvRect.tl().x, (long)opencvRect.tl().y, (long)opencvRect.br().x - 1, (long)opencvRect.br().y - 1);
