A system that detects different kinds of interference in squash (stroke, let, no let) -- 2

Need to use YOLO codes to identify players and squash ball. and use YOLO codes to identify the relative object position within the squash court and build birdeye view. Then crop the video clips into useful footage according to the conditions (i.e., stroke, let, and no let) specified at the excel spreadsheet at dropbox. At last, build classifier to differentiate the 3 conditions.
