Homography estimation on the Special Linear Group based on direct point correspondence

Hamel, Tarek; Mahony, Robert; Trumpf, Jochen; Morin, Pascal; Hua, Minh-Duc


This paper considers the question of obtaining a high quality estimate of a time-varying sequence of image homographies using point correspondences from an image sequence without requiring explicit computation of the individual homographies between any two given images. The approach uses the representation of a homography as an element of the Special Linear group and defines a nonlinear observer directly on this structure. We assume, either that the group velocity of the homography sequence is...[Show more]
