Reply to comment by Lethandralis in [D] Model for detecting rectangle corners? by hundley10

This might not work if the cards have 6 degrees of freedom. You can check out CornerNet and its variants for anchor free corner estimation. The original paper detects two corners, but extending to four should be possible.

Another option is to use yolo to detect a rough bbox, and then use classical cv to refine corner locations.
