Claims

C1strongest claim

We propose SAFAG, a novel Symmetry Annotation-Free framework for Generalizable and Actionable Parts Pose Estimation. Specifically, we suggest a stepwise refinement two-stage framework for candidate-to-final quaternion regression, and tackle the symmetry prediction as a probability distribution problem with self-supervised learning strategy.

C2weakest assumption

That self-supervised learning on symmetry as a probability distribution, combined with the two-stage candidate-to-final regression, will produce accurate and generalizable pose estimates without any symmetry annotations or rich labeled data.

C3one line summary

SAFAG introduces a symmetry annotation-free two-stage learning strategy for generalizable actionable parts pose estimation in robotics.
