Automatic Color Correction for Multisource Remote Sensing Images with Wasserstein CNN
Remote Sensing, 2017 In this paper a non-parametric model based on Wasserstein CNN is proposed for color correction. It is suitable for large-scale remote sensing image preprocessing from multiple sources under various viewing conditions, including illumination variances ...

Wasserstein Dissimilarity for Copula-Based Clustering of Time Series with Spatial Information
Mathematics, 2023 The clustering of time series with geo-referenced data requires a suitable dissimilarity matrix interpreting the comovements of the time series and taking into account the spatial constraints.

Cortically Based Optimal Transport
Journal of Mathematical Imaging and Vision, 2022 AbstractWe introduce a model for image morphing in the primary visual cortex V1 to perform completion of missing images in time. We model the output of simple cells through a family of Gabor filters and the propagation of the neural signal accordingly to the functional geometry induced by horizontal connectivity.

Gradient flow formulation of diffusion equations in the Wasserstein space over a Metric graph
Networks and Heterogeneous Media, 2022 This paper contains two contributions in the study of optimal transport on metric graphs. Firstly, we prove a Benamou–Brenier formula for the Wasserstein distance, which establishes the equivalence of static and dynamical optimal transport.

Architecture of optimal transport networks [PDF]
, 2005 We analyze the structure of networks minimizing the global resistance to flow (or dissipated energy) with respect to two different constraints: fixed total channel volume and fixed total channel surface area.

Immiscible color flows in optimal transport networks for image classification
Frontiers in Physics, 2023 In classification tasks, it is crucial to meaningfully exploit the information contained in the data. While much of the work in addressing these tasks is focused on building complex algorithmic infrastructures to process inputs in a black-box fashion ...

Quadratically Regularized Optimal Transport [PDF]
Applied Mathematics & Optimization, 2019 We investigate the problem of optimal transport in the so-called Kantorovich form, i.e. given two Radon measures on two compact sets, we seek an optimal transport plan which is another Radon measure on the product of the sets that has these two measures as marginals and minimizes a certain cost function.

Metasurfaces and Optimal transport
The SMAI Journal of computational mathematics, 2022 This paper provides a theoretical and numerical approach to show existence, uniqueness, and the numerical determination of metalenses refracting radiation with energy patterns. The theoretical part uses ideas from optimal transport and for the numerical solution we study and implement a damped Newton algorithm to solve the semi discrete problem.
