An Efficient Person Clustering Algorithm for Open Checkout-free Groceries. (arXiv:2208.02973v3 [cs.CV] UPDATED)

Open checkout-free grocery is the grocery store where the customers never
have to wait in line to check out. Developing a system like this is not trivial
since it faces challenges of recognizing the dynamic and massive flow of
people. In particular, a clustering method that can efficiently assign each
snapshot to the corresponding customer is essential for the system. In order to
address the unique challenges in the open checkout-free grocery, we propose an
efficient and effective person clustering …
