We present a method to find the correspondences between salient points of images in which an oracle can interact and influence on the final correspondences between points. The oracle looks up the current point correspondences and imposes new mappings or modifies some of them. This interaction influences on two aspects. On one hand, a new homography is computed such that the Least Square Error is minimized on the imposed correspondences. On the other hand, the Similarity Matrix between the set of points is modified and so, the interaction influences on the output of the Correspondence Algorithm. The method is independent of the algorithm to compute the homography and the correspondences. Practical evaluation shows that in few interactions of the oracle, the optimal correspondence is achieved.
