- Abstract:
-
In the task of 3D hand pose estimation from a single color image, challenges such as occlusion and high self-similarity of hand parts are faced, which lead to large prediction errors and unnatural hand structures. To address these issues, a graph convolution-based 3D hand pose estimation method is firstly proposed. Visual features and 2D keypoint positions are extracted from the input image using Keypoint R-CNN. These features are then fed into an improved Adaptive Kernel Graph Convolution module (AK_GraFormer). Subsequently, a residual-connected AKNN graph kernel is introduced to adaptively process graph-structured data, thereby enhancing the model’s feature learning and representation. Finally, a dynamic training strategy is employed, which is monitored by a proposed evaluation metric, to optimize estimation performance. Experimental results on the HO3D v3 and FreiHand datasets demonstrate that the proposed method outperforms existing approaches in monocular 3D hand pose estimation. Specifically, the Procrustes-Aligned Mean Per Joint Position Error (PA-MPJPE) is reduced by up to 17.83 percentage points, and the Area Under the Curve (AUC) of the Percentage of Correct Keypoints (PCK) metric is improved by up to 5.59 percentage points compared to state-of-the-art methods.
