A matter of notation: Several uses of the Kronecker product in 3D computer vision

This work presents a number of cases in Computer Vision where the introduction of the Kronecker product allows more elegant and compact derivations. We hold that a clear notation can enlighten properties and catalyze reasoning. In particular we introduce the trifocal matrix that allows to express the trilinear constraints among three views by using the familiar matrix algebra. (C) 2007 Elsevier B.V. All rights reserved.
