Platypose addresses the challenge of multi-hypothesis motion estimation by using a diffusion model pretrained on 3D human motion sequences. It focuses on generating temporally consistent samples for motion estimation, outperforming baseline methods. The framework is capable of zero-shot 3D pose sequence estimation and achieves competitive joint error when tested on static poses datasets like Human3.6M, MPI-INF-3DHP, and 3DPW. Platypose generalizes flexibly to different settings such as multi-camera inference. By incorporating uncertainties into estimates, it provides valuable insights for various applications like gait analysis, sports analytics, and character animation.
