Claim One:
1. A method for processing one or more images, comprising: generating, by a computing device, a plurality of pairs of keypoint features, with each pair of keypoint features including a first keypoint feature from a first of the one or more images, and a second keypoint feature from a second of the one or more images; generating, by the computing device, for each pair of keypoint features, a first plurality of adjoin features for the first keypoint feature of the keypoint feature pair, and a corresponding second plurality of adjoin features for the second keypoint feature of the keypoint feature pair, wherein the first plurality of adjoin features for the first keypoint feature are immediately adjacent to and circularly surround the first keypoint feature, and the second plurality of adjoin features for the second keypoint feature are immediately adjacent to and circularly surround the second keypoint feature; determining, by the computing device, for each pair of keypoint features, whether an immediately adjacent adjoin feature of the first keypoint feature of the keypoint feature pair is similar to the corresponding immediately adjacent adjoin feature of the second keypoint feature of the keypoint feature pair; and determining, by the computing device, whether the first and the second image have at least one similar object, based at least in part on a result of the determination of similarity between the corresponding immediately adjacent and circularly surrounding adjoin features of the first and second keypoint features of the keypoint feature pairs; wherein the first and second plurality of immediately adjacent and circularly surrounding adjoin features are generated based at least in part on an adjoin feature order; and wherein given a first keypoint feature of s i defined by at least [X i , r i , θ i ,] T , an adjoin feature order of K, the K immediately adjacent and circularly surrounding adjoin features of s i comprises s i * k defined by at least [X* k i , r i , θ i ,] T , where X* k i is defined by at least [X i , r i and α k ], where α k =θ i +2πk/K, k=1,2,. .. K−1, r i and θ i are point size and orientation of the keypoint feature s i .
