A Numerical Framework for Efficient Motion Estimation on Evolving Sphere-Like Surfaces based on Brightness and Mass Conservation Laws

1 code implementation2 May 2018 Lukas F. Lang

In this work we consider brightness and mass conservation laws for motion estimation on evolving Riemannian 2-manifolds that allow for a radial parametrisation from the 2-sphere.

A Dynamic Programming Solution to Bounded Dejittering Problems

no code implementations27 Mar 2017 Lukas F. Lang

We propose a dynamic programming solution to image dejittering problems with bounded displacements and obtain efficient algorithms for the removal of line jitter, line pixel jitter, and pixel jitter.

Optical Flow on Evolving Sphere-Like Surfaces

1 code implementation10 Jun 2015 Lukas F. Lang, Otmar Scherzer

In this work we consider optical flow on evolving Riemannian 2-manifolds which can be parametrised from the 2-sphere.

Decomposition of Optical Flow on the Sphere

1 code implementation16 Dec 2013 Clemens Kirisits, Lukas F. Lang, Otmar Scherzer

We propose a number of variational regularisation methods for the estimation and decomposition of motion fields on the $2$-sphere.
