OmniGlue: Generalizable Feature Matching with Foundation Model Guidance

Abstract

The image matching field has been witnessing a continuous emergence of novel learnable feature matching techniques with ever-improving performance on conventional benchmarks. However our investigation shows that despite these gains their potential for real-world applications is restricted by their limited generalization capabilities to novel image domains. In this paper we introduce OmniGlue the first learnable image matcher that is designed with generalization as a core principle. OmniGlue leverages broad knowledge from a vision foundation model to guide the feature matching process boosting generalization to domains not seen at training time. Additionally we propose a novel keypoint position-guided attention mechanism which disentangles spatial and appearance information leading to enhanced matching descriptors. We perform comprehensive experiments on a suite of 6 datasets with varied image domains including scene-level object-centric and aerial images. OmniGlue's novel components lead to relative gains on unseen domains of 20.9% with respect to a directly comparable reference model while also outperforming the recent LightGlue method by 9.5% relatively.
