I have a video file, I can run detect.net on it to do object classification.
I have radar datas related to video, so I know where is the object what I want to identify by detect.net. My target is to do the identification more effective way by examine just a part of every video frame.
Question 1: Is there any way to run detect.net just a determined part of the video?
Question 2: Does the whole procedure make sense? Does the procedure more effective if the size of the cropped video frames are 1/5 of the original size?
