Self-Supervised Geometric Correspondence for Category-Level 6D Object Pose Estimation in the Wild

We propose a self-supervised method for category-level 6D object pose estimation by learning dense 2D-3D geometric correspondences. Our method can train on in-the-wild RGB/RGBD image collections without any 3D annotations.

Semantic-Aware Fine-Grained Correspondence

We show that fine-grained features learned with low-level contrastive objectives are complementary to semantic features from image-level SSL methods. Fusing these features can significantly improve the performance for downstream tasks.
