Revisiting Sampson Approximations for Geometric Estimation Problems

no code implementations13 Jan 2024 Felix Rydell, Angélica Torres, Viktor Larsson

Many problems in computer vision can be formulated as geometric estimation problems, i. e. given a collection of measurements (e. g. point correspondences) we wish to fit a model (e. g. an essential matrix) that agrees with our observations.

1 code implementation5 Sep 2023 Marta Casanellas, Roser Homs Pons, Angélica Torres

In the last years, algebraic tools have been proven useful in phylogenetic reconstruction and model selection through the study of phylogenetic invariants.

Symbolic proof of bistability in reaction networks

no code implementations30 Sep 2019 Angélica Torres, Elisenda Feliu

Deciding whether and where a system of parametrized ordinary differential equations displays bistability, that is, has at least two asymptotically stable steady states for some choice of parameters, is a hard problem.
