手部姿态估计常用的评估指标：

• MPJPE/MPVPE measures the mean per joint/vertex position error by Euclidean distance (mm) between the estimated and ground-truth coordinates.

• F-Score is the harmonic mean between recall and precision between two meshes w.r .t. a specific distance threshold. F@5/F@15 corresponds to a threshold of 5mm/15mm.

• PA-MPJPE/MPVPE is a modification of MPJPE/MPVPE with Procrustes analysis , ignoring global variation. For conciseness, this metric is abbreviated as PJ/PV .

• AUC means the area under the curve of PCK (percentage of correct keypoints) vs. error thresholds of n ∼50mm (for 3D measurement) or 0∼30 pixel (for 2D measure-ment). According to [93, 92], n = 0 or 20.

• Acc captures the acceleration of 2D/3D joint landmarks in pixel/s2 or mm/s2 to reflect temporal coherence.
