Core Concepts
MESA, a novel approach, leverages advanced image segmentation capabilities to establish precise area matches, enabling efficient matching redundancy reduction and significantly improving the accuracy of various point matching methods.
Abstract
The paper proposes MESA, a method for precise area matching, to address the issue of matching redundancy in feature matching tasks.
Key highlights:
MESA utilizes the Segment Anything Model (SAM), a state-of-the-art foundation model for image segmentation, to obtain informative image areas without explicit semantic labels.
MESA constructs a novel multi-relational Area Graph (AG) to model the spatial structure and scale hierarchy of these image areas, enabling robust and efficient area matching.
MESA formulates the area matching as an energy minimization problem on two graphical models derived from the AG, which is effectively solved using the Graph Cut algorithm.
MESA introduces a learning-based area similarity calculation and a global matching energy refinement to achieve precise and robust area matches.
Extensive experiments demonstrate that MESA significantly improves the accuracy of various point matching methods in indoor and outdoor tasks, e.g., +13.61% for DKM in indoor pose estimation.
