1、imshow後選中視窗，Ctrl+C複製，Ctrl+S可儲存，避免用imwrite.
2、imreadmulti可以直接獲取資料夾中的多張圖；
3、imwrite()儲存多張圖片

Mat img1 = imread("./1.jpg", IMREAD_UNCHANGED);
Mat img2 = imread("./2.jpg", IMREAD_UNCHANGED);
imgs.push_back(img1);
imgs.push_back(img2);
imwrite("result.tif", imgs);
vector<Mat>imgs;
imreadmulti("./result.tif", imgs, IMREAD_UNCHANGED);
imshow("1", imgs.at(0));
imshow("2", imgs.at(1));
