This study proposes an underwater image instance segmentation algorithm based on YOLOv9 and an improved non-local module (non-local-s). By introducing the improved non-local module, the algorithm enhances the model’s ability to capture long-distance dependencies within images, thereby improving the accuracy of instance segmentation. Experimental results on the UIIS (Underwater Object Instance Segmentation) dataset demonstrate that the proposed algorithm significantly improves both accuracy and performance compared to existing state-of-the-art methods.

摘要

This study proposes an underwater image instance segmentation algorithm based on YOLOv9 and an improved non-local module (non-local-s). By introducing the improved non-local module, the algorithm enhances the model’s ability to capture long-distance dependencies within images, thereby improving the accuracy of instance segmentation. Experimental results on the UIIS (Underwater Object Instance Segmentation) dataset demonstrate that the proposed algorithm significantly improves both accuracy and performance compared to existing state-of-the-art methods.
