On Assignment Problems Related to Gromov-Wasserstein Distances on the Real Line

Robert Beinert, Cosmas Heiss, Gabriele Steidl

Let $x_{1} < \dots < x_{n}$ and $y_{1} < \dots < y_{n}$ , $n \in N$ , be real numbers. We show by an example that the assignment problem $$ \max_{σ\in S_n} F_σ(x,y) := \frac12 \sum_{…

Lagrangian Motion Magnification with Double Sparse Optical Flow Decomposition

Philipp Flotho, Cosmas Heiss, Gabriele Steidl +1

Microexpressions are fast and spatially small facial expressions that are difficult to detect. Therefore motion magnification techniques, which aim at amplifying and hence revealin…
