Rethinking Object Detection in Retail Stores

1 code implementation18 Mar 2020 Yuan-Qiang Cai, Longyin Wen, Libo Zhang, Dawei Du, Weiqiang Wang

In this paper, we propose a new task, ie, simultaneously object localization and counting, abbreviated as Locount, which requires algorithms to localize groups of objects of interest with the number of instances.
