Abstract

En 中文

Keypoint detection is a core task in the visual domain, facing challenges such as occlusion, false detection, and complex poses. To address these issues, an efficient keypoint detection algorithm, EKD-YOLO, based on the YOLOv8s model, is proposed. Firstly, in case of enhancing the model’s feature fusion capability, the Fusion-Neck architecture is depicted to replace the original Neck part of YOLOv8. Secondly, for the purpose of improving model efficiency, the feature extraction module has been optimized by proposing a more lightweight C2fiAFF module and introduces the SCDown module. Furthermore, in order to improve accuracy and precision, an efficient attention mechanism, C2iEMA is designed. Experimental data indicate, compared to the YOLOv8s model, the improved EKD-YOLO algorithm achieved a 2.5% increase in mAP@0.5, a 4% improvement in P%, and a reduction in FLOPs and parameter count. The overall performance of the model was enhanced. Our code and models are available at https://github.com/geleerde/EKD-YOLO .
