Mat转matrix<dlib::rgb_pixel>

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

值得注意的地方：matrix<dlib::rgb_pixel>img不能放进vector<matrix<dlib::rgb_pixel>>img，会报错！

array2d<dlib::bgr_pixel>转Mat

方法一： dlib::array2d<dlib::bgr_pixel> img_bgr;//使用dlib载入彩色的RGB图像 dlib::load_image(img_bgr, "test_image.jpg"); cv::Mat img = dlib::toMat(img_bgr);//这样图片不失真

方法二：

cv::Mat temp_Roi; temp_Roi=imread("1.jpg"); array2d< bgr_pixel> img(temp_Roi.rows, temp_Roi.cols); for (int i = 0; i < temp_Roi.rows; i++) {     for (int j = 0; j < temp_Roi.cols; j++)     {         img[i][j].blue = temp_Roi.at< cv::Vec3b>(i, j)[0];         img[i][j].green = temp_Roi.at< cv::Vec3b>(i, j)[1];         img[i][j].red = temp_Roi.at< cv::Vec3b>(i, j)[2];     } }点击打开链接

Mat转cv_image<rgb_pixel>

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

Mat转cv_image<bgr_pixel>

cv::Mat temp; cv_image<bgr_pixel> cimg(temp);

Opencv的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);

Mat转dlib array2d

#include "dlib/opencv/cv_image.h" //需要的头文件 cv::Mat ori_rgb_mat,photo_gray; // RGB dlib::array2d<dlib::bgr_pixel> dlib_image; dlib::assign_image(dlib_image, dlib::cv_image<dlib::bgr_pixel>(ori_rgb_mat)); // Gray //dlib::array2d<unsigned char> dlibImageGray; //dlib::assign_image(dlibImageGray, dlib::cv_image<unsigned char>(photo_gray));
