"""Yolo v3 detection script. | ||
Saves the detections in the `detection` folder. | ||
Usage: | ||
python detect.py <images/video> <iou threshold> <confidence threshold> <filenames> | ||
Example: | ||
python detect.py images 0.5 0.5 data/images/dog.jpg data/images/office.jpg | ||
python detect.py video 0.5 0.5 data/video/shinjuku.mp4 | ||
Note that only one video can be processed at one run. | ||
