Pose2met: a unified spatiotemporal framework for 3D human pose estimation and energy expenditure estimation
The Pose2Met framework introduces a novel, end-to-end solution for jointly addressing 3D Human Pose Estimation (HPE) and Energy Expenditure Estimation (EEE). By leveraging a SpatioTemporal Aggregated Pose (STAP) representation within a Transformer model (STAPFormer), Pose2Met accurately models complex human activities. This unified approach not only achieves state-of-the-art performance in 3D HPE with a Mean Per-Joint Position Error (MPJPE) of 38.2 mm on Human3.6M, outperforming existing methods like MixSTE and STCFormer, but also delivers robust EEE with 22.1 kcal MAE on Vid2Burn-ADL, comparable to video-based methods. The framework significantly enhances computational efficiency, generalization, and robustness in real-world applications, offering a promising direction for intelligent fitness and healthcare.

Enhanced 3D Pose Accuracy with STAPFormer
Pose2Met introduces STAPFormer, a Transformer model with a SpatioTemporal Aggregated Pose (STAP) representation. This architecture is designed to capture collaborative motion patterns between local and global body parts, leading to superior accuracy in 3D human pose estimation.
Robust Energy Expenditure Estimation
Leveraging high-quality motion representations from its pose estimation capabilities, Pose2Met provides accurate energy expenditure prediction directly from 2D pose inputs. Its physiologically inspired formulation models frame-level energy fluctuations, enhancing the informativeness of the supervisory signal.
Seamless Integration for Joint Optimization
The core innovation lies in Pose2Met's unified end-to-end learning strategy, which jointly optimizes both 3D pose estimation and energy expenditure prediction. This design fosters cross-task feature coupling, improves computational efficiency, and enhances robustness across diverse activities.
Efficiency and Generalization for Practical Use
Experiments on benchmark datasets demonstrate Pose2Met's strong generalization to unseen activities and its real-time processing capabilities. This makes it a viable solution for intelligent fitness, proactive healthcare, and dynamic motion understanding in real-world scenarios, surpassing many diffusion-based methods in practicality.
