- Abstract:
-
In the task of 3D hand pose estimation from a single image in color, challenges such as occlusion and high self‑similarity of hand parts might lead to large prediction errors and unnatural hand structures. To address these issues, a graph convolution‑based 3D hand pose estimation method was firstly proposed. Visual features and 2D keypoint positions were extracted from the input image using Keypoint R‑CNN. These features were then fed into an improved adaptive kernel graph convolution module (AK_GraFormer). Subsequently, a residual‑connected AKGNN graph kernel was introduced to adaptively process graph‑structured data, thereby enhancing the model’s feature learning and representation. Finally, a dynamic training strategy was employed, which was monitored by a proposed evaluation metric, to optimize estimation performance. Experimental results on the HO‑3D_v3 and FreiHand datasets demonstrated that the proposed method outperformed existing approaches in monocular 3D hand pose estimation. Specifically, the procrustes‑aligned mean per joint position error (PA‑MPJPE) was reduced by up to 12.50 percentage points, and the area under the curve (AUC) of the percentage of correct keypoints metric was improved by up to 3.44 percentage points compared to state‑of‑the‑art methods.
