Multiprojective Geometry of Compatible Triples of Fundamental and Essential Matrices
Timothy Duff, Viktor Korotynskiy, Anton Leykin +1
We characterize the variety of compatible fundamental matrix triples by computing its multidegree and multihomogeneous vanishing ideal. This answers the first interesting case of a…

Minimal Perspective Autocalibration
Andrea Porfiri Dal Cin, Timothy Duff, Luca Magri +1
We introduce a new family of minimal problems for reconstruction from multiple views. Our primary focus is a novel approach to autocalibration, a long-standing problem in computer…
