Global Optimisation for Improved Volume Tracking of Time-Varying Meshes
Jan Dvořák, Filip Hácha, Libor Váša
International Conference on Computational Science (ICCS) 2023
paper
/ bibtex
/ code
We propose improved center affinity based on maximum value encountered up to the currently processed frame. We also detect and filter irregularities and perform a global optimisation in post processing to further improve the tracking quality.

Priority-based encoding of triangle mesh connectivity for a known geometry
Jan Dvořák, Zuzana Káčereková, Petr Vaněček, Libor Váša
Computer Graphics Forum, vol. 42, no. 1, pp. 60–71, Nov. 2022
paper
/ bibtex
/ code
In this work, we propose a priority-driven approach for encoding mesh connectivity, if the geometry is already known (e.g., encoded separately using inter-frame prediction).

As-rigid-as-possible volume tracking for time-varying surfaces
Jan Dvořák, Zuzana Káčereková, Petr Vaněček, Lukáš Hruda, Libor Váša
Computers & Graphics, vol. 102, pp. 329–338, Feb. 2022
paper
/ bibtex
/ code
We were able to improve the original volume tracking pipeline by incorporating ARAP motion energy and a different notion of center affinity based on similarity of motion.

Towards Understanding Time Varying Triangle Meshes
Jan Dvořák, Petr Vaněček, Libor Váša
International Conference on Computational Science (ICCS) 2021
paper
/ bibtex
In this work, we propose a volume tracking method for time-varying surfaces of evolving topology. The main idea of the approach is that in the presence of self-contacts, the volume correspondences are more likely bijective than surface correspondences.

Predictive compression of molecular dynamics trajectories
Jan Dvořák, Martin Maňák, Libor Váša
Journal of Molecular Graphics and Modelling 96, p. 107531, May 2020
paper
/ bibtex
/ project
In this work, we propose a compression method for molecular dynamics trajectories exploiting the knowledge of molecular bonds.

Error propagation control in Laplacian mesh compression
Libor Váša, Jan Dvořák
Computer Graphics Forum, vol. 37, no. 5, pp. 61–70, Aug. 2018
paper
/ bibtex
/ project
We were able to improve performance of High-pass coding approach (also known as Laplacian compression) under mechanistic error metrics like MSE.
