Warped Convolution Networks for Homography Estimation. (arXiv:2206.11657v1 [cs.CV])

Homography transformation has an essential relationship with special linear
group and the embedding Lie algebra structure. Although the Lie algebra
representation is elegant, few researchers have established the connection
between homography estimation and algebra expression. In this paper, we propose
Warped Convolution Networks (WCN) to effectively estimate the homography
transformation by SL(3) group and sl(3) algebra with group convolution. To this
end, six commutative subgroups within SL(3) group are composed to form a
homography transformation. For each subgroup, a warping …
