Making affine correspondences work in camera geometry computation
Local features eg. SIFT and its affine and learned variants provide region-to-region rather
than point-to-point correspondences. This has recently been exploited to create new …

Theory and practice of structure-from-motion using affine correspondences
Abstract Affine Correspondences (ACs) are more informative than Point Correspondences
(PCs) that are used as input in mainstream algorithms for Structure-from-Motion (SfM). Since …

Efficient recovery of essential matrix from two affine correspondences
We propose a method to estimate the essential matrix using two affine correspondences for
a pair of calibrated perspective cameras. Two novel, linear constraints are derived between …

Conic epipolar constraints from affine correspondences
J Bentolila, JM Francos - Computer Vision and Image Understanding, 2014 - Elsevier
We derive an explicit relation between local affine approximations resulting from matching of
affine invariant regions and the epipolar geometry in the case of a two view geometry. Most …
