-Besides the detection video, other outputs of the program consist of a message on the terminal, a detection performance graph, and a CSV file. The terminal message and the resulting performance graph can be observed below. The performance visualized here consists of the delay time between camera and IR sensor detection, frame rate, and detected/undetected object ratio.
