Optical flow estimation using the Fisher–Rao metric [PDF]
Neuromorphic Computing and Engineering, 2021 Abstract The optical flow in an event camera is estimated using measurements in the address event representation (AER). Each measurement consists of a pixel address and the time at which a change in the pixel value equalled a given fixed threshold.

The $$L^p$$-Fisher–Rao metric and Amari–C̆encov $$\alpha $$-Connections [PDF]
Calculus of Variations and Partial Differential Equations, 2023 AbstractWe introduce a family of Finsler metrics, called the $$L^p$$ L p -Fisher–Rao metrics $$F_p$$ F p , for $$p\in (1,\infty )$$

Bayesian sensitivity analysis with the Fisher–Rao metric [PDF]
Biometrika, 2015 We propose a geometric framework to assess sensitivity of Bayesian procedures to modelling assumptions based on the nonparametric Fisher–Rao metric. While the framework is general, the focus of this article is on assessing local and global robustness in Bayesian procedures with respect to perturbations of the likelihood and prior, and on the ...

Riemannian cubics on the group of diffeomorphisms and the Fisher-Rao metric [PDF]
, 2016 We study a second-order variational problem on the group of diffeomorphisms of the interval [0, 1] endowed with a right-invariant Sobolev metric of order 2, which consists in the minimization of the acceleration. We compute the relaxation of the problem which involves the so-called Fisher-Rao functional a convex functional on the space of measures ...

, 2008 The information in a mass of data is summarised by fitting to the data a probability density function (pdf) chosen from a parameterised family of pdfs. Distances between pairs of pdfs are calculated using the Fisher-Rao metric, which provides a measure ...

A JKO Splitting Scheme for Kantorovich--Fisher--Rao Gradient Flows
, 2017 International audienceIn this article we set up a splitting variant of the JKO scheme in order to handle gradient flows with respect to the Kantorovich-Fisher-Rao metric , recently introduced and defined on the space of positive Radon measure with ...

Uniqueness of the Fisher–Rao metric on the space of smooth densities [PDF]
Bulletin of the London Mathematical Society, 2016 On a closed manifold of dimension greater than one, every smooth weak Riemannian metric on the space of smooth positive probability densities, that is invariant under the action of the diffeomorphism group, is a multiple of the Fisher--Rao metric.
