To address these issues, we propose the YOLO11-FGA algorithm, an enhanced version of the YOLO11n model designed to improve both detection accuracy and response speed. The key innovation in this model is the introduction of the FasterNet backbone, which enhances the feature extraction capabilities while maintaining a lightweight design, thus improving overall computational efficiency. Additionally, we incorporate the C3k2_GhostDynamicConv module, which combines the GhostBottleneck and DynamicConv structures to significantly enhance the detection and feature extraction capabilities, particularly for subtle and complex packaging defects. To further improve detection performance, an Auxiliary training head (Aux) is added to the YOLO11 detection head, enhancing multi-scale feature fusion and boosting the accuracy of small target detection, which is essential for identifying minor defects. Experimental results demonstrate that YOLO11-FGA outperforms YOLO11n, with improvements in accuracy (1.1%), recall (1.3%), mAP@0.5 (2.3%), and mAP@0.5:0.95 (1.4%). These results highlight the superior performance of the YOLO11-FGA algorithm, which offers enhanced detection accuracy, robustness, and computational efficiency, making it a highly effective solution for real-time express parcel quality detection in logistics applications.<\/jats:p>","DOI":"10.3390\/info16121021","type":"journal-article","created":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T09:02:07Z","timestamp":1763974927000},"page":"1021","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["YOLO11-FGA: Express Package Quality Detection Based on Improved YOLO11"],"prefix":"10.3390","volume":"16","author":[{"given":"Peng","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Taiyuan Normal University, Jinzhong 030619, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guanglei","family":"Qiang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Taiyuan Normal University, Jinzhong 030619, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangrui","family":"Fan","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Taiyuan Normal University, Jinzhong 030619, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Du","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Taiyuan Normal University, Jinzhong 030619, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junye","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Taiyuan Normal University, Jinzhong 030619, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2962-6334","authenticated-orcid":false,"given":"Zhen","family":"Tian","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering, University of Glasgow, Glasgow G12 8QQ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1108\/IJLM-04-2023-0149","article-title":"Drones in last-mile delivery: A systematic literature review from a logistics management perspective","volume":"36","author":"Jazairy","year":"2025","journal-title":"Int.
