| 摘要 |
The invention relates to a method (100) for detecting incorrect associations between keypoints of a first image and keypoints of a second image, keypoints of the first image indicating characteristic features of the first image being associated with keypoints of the second image indicating characteristic features of the second image whereby initial associations between keypoints of the first image and keypoints of the second image are formed, the initial associations being indicated by an indicator, the initial associations comprising the incorrect associations, the method (100) comprising associating (101) every keypoint of the first image with every keypoint of the second image to obtain global associations, determining (103) similarity measures for pairs of initial associations, determining (105) similarity measures for pairs of global associations, determining (107) a first number of pairs of initial associations having a similarity measure within a predetermined range, determining (109) a second number of pairs of global associations having a similarity measure within the predetermined range, and comparing (111) the first number of pairs with the second number of pairs to detect the incorrect associations. The invention further relates to an apparatus for detecting incorrect associations between keypoints of a first image and keypoints of a second image. |
