We analyze the difficulties encountered in underwater small object detection with deep learning methods when training samples are limited and propose corresponding solutions to address these challenges. To address the challenges of unclear object contours and blurred feature details in sonar images, we employ a transformer-based object detector that leverages the attention mechanism to effectively utilize global image information for precise object localization and identification. To handle the prevalence of small targets, we design a Multi-Branch Feature Extraction Module that aggregates feature maps with different receptive fields, thereby enhancing the effective utilization of small object features. In addition, the core design of the RT-DETR model is incorporated as the baseline architecture, which significantly improves the real-time performance of the detector. To overcome the challenge of limited training data, we apply transfer learning by first training the entire MP-DETR (More Precise DETR) network on a large-scale, general-purpose dataset. Then the IOU-aware query selection module and detection head of the MP-DETR network is finetuned using a self-compiled underwater small sample sonar image training dataset. The proposed approach achieves a deep neural network suitable for underwater object detection based on sonar images. Experiments were conducted on a self-constructed underwater small-sample sonar image dataset, and the proposed MP-DETR achieved 98.5% mean average precision (MAP) and 53 frames per second (FPS) real-time performance, which provides higher detection accuracy and real-time performance compared with existing methods.<\/jats:p>","DOI":"10.15837\/ijccc.2026.4.6915","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T08:48:35Z","timestamp":1783414115000},"source":"Crossref","is-referenced-by-count":0,"title":["A Few-shot Learning Algorithm for Underwater Small Object Detection based on the Transformer Architecture"],"prefix":"10.15837","volume":"21","author":[{"given":"Xiaobing","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyu","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panlong","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6528","published-online":{"date-parts":[[2026,7,7]]},"container-title":["INTERNATIONAL JOURNAL OF COMPUTERS  COMMUNICATIONS &amp; CONTROL"],"original-title":[],"deposited":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T08:48:35Z","timestamp":1783414115000},"score":1,"resource":{"primary":{"URL":"https:\/\/univagora.ro\/jour\/index.php\/ijccc\/article\/view\/6915"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,7]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026,7,7]]}},"URL":"https:\/\/doi.org\/10.15837\/ijccc.2026.4.6915","relation":{},"ISSN":["1841-9844","1841-9836"],"issn-type":[{"value":"1841-9844","type":"electronic"},{"value":"1841-9836","type":"print"}],"subject":[],"published":{"date-parts":[[2026,7,7]]}}}
