3D human pose estimation from a single image is a challenging problem,
especially for in-the-wild settings due to the lack of 3D annotated data. We
propose two anatomically inspired loss functions and use them with a
weakly-supervised learning framework to jointly learn from large-scale
in-the-wild 2D and indoor/synthetic 3D data. We also present a simple temporal
network that exploits temporal and structural cues present in predicted pose
sequences to temporally harmonize the pose estimations. We carefully analyze
the proposed contributions through loss surface visualizations and sensitivity
analysis to facilitate deeper understanding of their working mechanism. Our
complete pipeline improves the state-of-the-art by 11.8% and 12% on Human3.6M
and MPI-INF-3DHP, respectively, and runs at 30 FPS on a commodity graphics
card.

使用两种解剖启发的损失函数和弱监督学习框架，结合大规模野外 2D 和室内 / 合成 3D 数据共同学习人体姿态估计。还提出了一个简单的时间网络来调和预测的姿态序列，并通过损失表面可视化和敏感性分析仔细分析了所提出的贡献的工作机制。我们的完整流程在 Human3.6M 和 MPI-INF-3DHP 上分别提高了 11.8％和 12％，并在普通图形卡上以 30 FPS 运行。
