You can use different methods available while handling numpy arrays, because after reading images from OpenCV you will get that image as numpy array. Just use different methods like .size(), .shape(), etc to get the structure of data present and try to print a few data to get an overall idea.
Dear Deshmukh, Abhishek (Intel) ,
Thank you for your help. May I ask you a little more ?
How can I check the numpy array ? (For example, in the [security_barrier_camera_demo] ?)
