Fig. 2From: Robustly building keypoint mappings with global information on multispectral imagesComparison of the keypoint mappings on an image pair that contains similar local intensity/gradient patterns. Due to this, in (e), the keypoints near the tail lights of the two cars in left image are mapped to keypoints near a window in the right image. a The proposed method, b SIFT descriptors [33], c ISS descriptors [27], d ORB descriptors [29], and e FREAK descriptors [14]Back to article page
