英文摘要Correspondence Selection (CS) identifies the reliable correspondences from the putative ones. It provides fundamental cues for many computer vision tasks, therefore the performance and efficiency of CS are pivotal. Previous methods are either accurate but timeconsuming process or efficient but ambiguous. It is difficult to strike a good balance between performance and efficiency. In this paper, we propose the Onion-ring Support Neighbors (OSN) method for CS. OSN can fully exhaust the coherency information of neighbors to identify all reliable correspondences but it only requires the O(n) time and space complexity. To our best knowledge, we are the first to prove that the performance of CS can be improved by considering information from more neighbors. To this end, onion ring shaped support neighbors are introduced, whereby the directional relationships can be eliminated from the central region to neighbor regions, and rotation invariance in putative correspondences can be retained. To efficiently identify the reliable correspondences, we present the Fixed Correspondence algorithm. This algorithm can reduce the search space of putative correspondences within constant time, which contributes to a O(n) time complexity of the overall OSN process. Extensive experiments over widely used datasets show that OSN achieves state-of-the-art performance in F1-measure and Pose estimation. (C) 2021 Elsevier Inc. All rights reserved.
