About this paper
István Sárándi, Alexander Hermans, Bastian Leibe
Researchers at RWTH Aachen University developed a geometry-aware autoencoder to systematically combine 28 diverse 3D human pose datasets, which previously had incompatible skeleton formats. This approach enabled training a single 3D human pose estimator that achieved state-of-the-art performance on multiple benchmarks, notably improving consistency and generalization to "in-the-wild" scenarios.
Key insights
- Leveraging an "extreme multi-dataset regime" with dozens of diverse datasets significantly boosts 3D human pose estimation performance, especially in unconstrained environments.
- Simply merging identically named joints across datasets is insufficient and detrimental, as subtle anatomical differences render such an approach ineffective.
- A geometry-aware autoencoder can learn a robust, consistent latent representation that effectively reconciles diverse and incompatible 3D skeleton formats.
