Optimal Transport for Kernel Gaussian Mixture Models

no code implementations28 Oct 2023 Jung Hun Oh, Rena Elkin, Anish Kumar Simhal, Jiening Zhu, Joseph O Deasy, Allen Tannenbaum

The Wasserstein distance from optimal mass transport (OMT) is a powerful mathematical tool with numerous applications that provides a natural measure of the distance between two probability distributions.

Wasserstein Image Local Analysis: Histogram of Orientations, Smoothing and Edge Detection

no code implementations11 May 2022 Jiening Zhu, Harini Veeraraghavan, Larry Norton, Joseph O. Deasy, Allen Tannenbaum

We approach the directionality problem from a novel perspective by the use of the optimal transport map of a local image patch to a uni-color patch of its mean.
