Unity is not as hard as I thought before
Unity is not as hard as I thought, although I am a newbie in this field. I believe my little step leads me to the future. After a day of playing in the Unity world for the first time. I felt great when I finished a small project. In this project, I tried to integrate EmguCV, which is a wrapped OpenCV for .net framework, into the Unity C# program and did a simple face detection. Each face's location represents an NBA player's position. For example, Stephen Curry is corresponding to face #0, Lebron James is face #1, and Ja Morant is face #2. As the video plays, all the NBA players can move to the locations according to their face numbers.

How to find out if the rectangle inside another rectangle?
cv::Mat img(cv::Size(800, 800), CV_8UC3);
// big region of interest (ROI)
Rect roi(100, 100, 400, 400);
rectangle(img, roi, Scalar(255, 0, 0), 1);
// some rectangles
vector<Rect> lpROIs;
lpROIs.push_back(Rect(30, 50, 100, 100));
lpROIs.push_back(Rect(420, 250, 100, 100));
lpROIs.push_back(Rect(150, 140, 100, 100));
lpROIs.push_back(Rect(300, 100, 100, 100));
lpROIs.push_back(Rect(250, 250, 100, 100));
lpROIs.push_back(Rect(300, 450, 100, 100));
// check out if the rectangle inside the ROI
for(int i=0; i<lpROIs.size(); i++)
{
// inside the ROI
if( (roi&lpROIs[i])==lpROIs[i] )
rectangle(img, lpROIs[i], Scalar(0,0,255), -1);
else
rectangle(img, lpROIs[i], Scalar(0,255,0), 1);
}
imshow("img", img);
