Main.cpp runs the main code blob.h and blob.cpp are the additional headers
this code is to be compiled with OpenCV 4.1+ installed on the devce. The code is able to detect and track moving objects using image substraction on two seperate cameras.
Cam A is set to be the IN camera, and the B cam is set to be the OUT camera. When the virtual line on A is crossed, the trigger count will move one up, and when the line on B is crossed, the count will move one down.
