Original Abstract Submitted
feature descriptor matching is reformulated into a graph-matching problem. keypoints from a query image and a reference image are initially matched and filtered based on the match. for a given keypoint, a feature graph is constructed based on neighboring keypoints surrounding the given keypoint. the feature graph is compared to a corresponding feature graph of a reference image for the matched keypoint. relocalization data is obtained based on the comparison.
