The YOLOv5 algorithm is used to detect commodities in the checkout image, generate a set of localization frames and segment the targets. For the problem that YOLOv5 is insensitive to small targets, a detection layer is added to the YOLOv5 network structure, and the loss function and bounding box localization error are optimized to improve the model detection performance. On this basis, the SCDA algorithm is used to match the registered commodity map in the database with the segmented commodity map to complete the commodity detection and recognition. The experimental results show that the algorithm in this paper improves the accuracy rate by 3.75% relative to DPNet and achieves 80.79% mAP on the whole test set.<\/jats:p>","DOI":"10.3233\/faia230786","type":"book-chapter","created":{"date-parts":[[2023,12,1]],"date-time":"2023-12-01T15:52:29Z","timestamp":1701445949000},"source":"Crossref","is-referenced-by-count":0,"title":["Image Retrieval-Based Product Identification for Automatic Checkout Systems"],"prefix":"10.3233","author":[{"given":"Haitao","family":"Lu","sequence":"first","affiliation":[{"name":"School of Geodesy and Geomatics, Wuhan University, Wuhan, Hubei, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Advances in Artificial Intelligence, Big Data and Algorithms"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA230786","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,1]],"date-time":"2023-12-01T15:52:31Z","timestamp":1701445951000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA230786"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,11,30]]},"ISBN":["9781643684444","9781643684451"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia230786","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,11,30]]}}}
