Feature-based groupwise registration of historical aerial images to present-day ortho-photo maps | Sebastian Zambanini
; | Date: |
22 Nov 2018 | Abstract: | In this paper, we address the registration of historical WWII images to
present-day ortho-photo maps for the purpose of geolocalization. Due to the
challenging nature of this problem, we propose to register the images jointly
as a group rather than in a step-by-step manner. To this end, we exploit Hough
Voting spaces as pairwise registration estimators and show how they can be
integrated into a probabilistic groupwise registration framework that can be
efficiently optimized. The feature-based nature of our registration framework
allows to register images with a-priori unknown translational and rotational
relations, and is also able to handle scale changes of up to 30% in our test
data due to a final geometrically guided matching step. The superiority of the
proposed method over existing pairwise and groupwise registration methods is
demonstrated on eight highly challenging sets of historical images with
corresponding ortho-photo maps. | Source: | arXiv, 1811.9081 | Services: | Forum | Review | PDF | Favorites |
