The tutorial Jetson OpenCV Tutorials - Episode 0 (https://www.youtube.com/watch?v=gvmP0WRVUxI ) has an error. The program hello.cpp should include the line
because ‘putText’ not a member of cv. It is now in imgproc.hpp
The tutorial mentioned above should be redone. This is because (1) the person doing the tutorial clicks on too quickly,so we cant see what was typed, and (2) the size of the characters on the screen are too small to read easily. Also, (3) the person giving the tutorial has a very strong accent. It is hard to follow.
