The program for detecting the green ball is named ObjectDetection.cpp and I have saved it inside the OpenCV_codes folder. I have also copied the greenball.png image to this folder. You can download the ObjectDetection.cpp program from the Chapter07 folder of the GitHub repository. So, the program for detecting the green ball is as follows:
