The dynamic pyramid—a model for motion analysis with controlled continuity
Joachim Dengler,Markus Schmidt +1 more
TL;DR: The Dynamic Pyramid as discussed by the authors is a model to solve the correspondence problem of image sequences, where a robust estimation of local displacements is combined with controlled continuity constraints, and the displacement term of the functional is based on robust local binary correlations derived from the signs of the bandpass filtered images.

Adapting multi-grid-methods to the class of elliptic partial differential equation appearing in the estimation of displacement vector fields
Markus Schmidt,Joachim Dengler +1 more
TL;DR: In this article, a multi-grid approach for solving large linear or nonlinear equations, which are typical for early vision problems, is presented. And convergence results show the possibility of a real-time implementation of this displacement vector field approach.

TL;DR: Convergence results show the possibility of a realtime implementation of a Multi-Grid approach to estimate a displacement vector field from two images with fixed iteration number of a conjugate gradient smoothing operator under use of special design conditions.

A multi-resolution approach to the 3D reconstruction from an electron microscope tilt series solving the alignment problem without gold particles
TL;DR: In this paper, a multi-resolution approach to the 3D-reconstruction problem from electron microscope tilt series is presented, which is designed for the reconstruction from a tilt series with a limited number of projections where the tilt angles are assumed to be known.
Local motion estimation with the dynamic pyramid

- 01 Oct 1986
TL;DR: The Dynamic Pyramid is a tool for analyzing monocular moving image sequences based on the physical model of the elastic membrane, where the cost function consisting of the similarity between the frames and the deformation of the transformation vector field is minimized.
