Proving the Existence of a GOR Without Probability

Steven J. Gortler, Louis Theran

In this note, we provide a new proof that a $D$ -connected graph $G$ on $n$ vertices has a general position orthogonal representation in $\RR^{n-D}$. Our argument, while based on ma…

General position stresses

Robert Connelly, Steven J. Gortler, Louis Theran

Let $G$ be a graph with $n$ vertices, and $d$ be a target dimension. In this paper we study the set of rank $n - d - 1$ matrices that are equilibrium stress matrices for at least one (…

Universal Rigidity of Ladders on the line

Bryan Chen, Robert Connelly, Steven J. Gortler +2

In "Universal rigidity on the line, point orde" it is shown, answering a question of Jordán and Nguyen, that universal rigidity of a generic bar-joint framework in R^1 depends on m…

Low-level Vision by Consensus in a Spatial Hierarchy of Regions

Ayan Chakrabarti, Ying Xiong, Steven J. Gortler +1

We introduce a multi-scale framework for low-level vision, where the goal is estimating physical scene values from image data---such as depth from stereo image pairs. The framework…
