??? ?在Dlib庫中圖像存儲是使用array2d類型，而在OpenCV是使用Mat類型，Dlib中提供了#include <dlib/opencv.h>，可實現dlib array2d與 OpenCV Mat的互轉。其中toMat對象可將dlib的圖像轉為OpenCV的Mat類型，而cv_image對象可將OpenCV的Mat類型轉為dlib類型的圖像。詳見官網：http://dlib.net/imaging.html#rgb_pixel

//dlib::array2d is an image already, you can use it for any dlib's image functions //load image: dlib::array2d<dlib::rgb_pixel> img_rgb;//使用dlib載入彩色的RGB圖像 dlib::load_image(img_rgb, "test_image.jpg");//convert to greyscale: dlib::array2d<unsigned char> img_gray;//使用dlib載入灰度圖像 dlib::load_image(img_gray, "test_image.jpg"); //或者 dlib::assign_image(img_gray, img_rgb);//converto to OpenCV Image (cv::Mat): #include <dlib/opencv.h> #include <opencv2/opencv.hpp> cv::Mat img = dlib::toMat(img_rgb);//RGB圖像 cv::Mat img = dlib::toMat(img_gray);//灰度圖像//get image from OpenCV: #include <dlib/opencv.h> #include <opencv2/opencv.hpp> cv::Mat img = cv::imread("test_image.jpg") dlib::cv_image<rgb_pixel> dlib_img(img); // only stores pointer, no deep copy //Documentation is here. There are a lot of well-documented examples, you should start from them. Special example about array2ddlib array2d轉 OpenCV Mat時顏色失真

dlib array2d轉 OpenCV Mat時，會出現顏色失真的現象，其解決方法是：http://blog.csdn.net/guyuealian/article/details/77482549
