SOCO benchmark debuts at ECCV 2026: 1M+ pairs probe how vision models grasp object structure

Researchers from Max Planck Institute, CISPA, and University of Freiburg introduce SOCO (Semantic Object Correspondence), a benchmark accepted as an ECCV 2026 Spotlight that systematically evaluates how well vision foundation models (VFMs) and large vision-language models (LVLMs) understand object parts and structure.
Key points:
- Covers 100 diverse categories with over 1M correspondence pairs, plus consistent, functionally meaningful keypoint annotations
- Introduces a taxonomy of correspondence types and language descriptions of keypoints, enabling evaluation of fine-grained part-level understanding in LVLMs
- Findings: vision backbones encode strong semantic structure but transfer correspondences poorly across related categories and only partially capture part positions; LVLMs are better at text-prompted part localisation than visual-reference cross-image matching
