示例1: cvmatconcat
void cvmatconcat(cv::Mat img1, cv::Mat img2, cv::Mat &out)
{
cv::Size size1;
cv::Size size2;
// setup
size1 = img1.size();
size2 = img2.size();
out = cv::Mat(
size1.height,
size1.width + size2.width,
img1.type()
);
// copy image 1 to the left
out.adjustROI(0, 0, 0, -size2.width);
img1.copyTo(out);
// copy image 2 to the right
out.adjustROI(0, 0, -size1.width, size2.width);
