The corresponding point coordinates determined by classic image matching approaches define local zero-order approximations of the global mapping between two images. But patches around keypoints typically contain more information, which may be exploited to obtain a first-order approximation mapping, incorporating affine maps keypoints. Several methods have been proposed in literature compute thi...

Summary Estimators based on Wasserstein distributionally robust optimization are obtained as solutions of min-max problems in which the statistician selects a parameter minimizing worst-case loss among all probability models within certain distance from underlying empirical measure sense. While motivated by need to identify optimal model parameters or decision choices that misspecification, the...
