T4transport 0.1.9
- The
rbaryGD() function allows arbitrary step-size selection for $\alpha \in (0,1]$ provided by a user. Default is $\alpha=1$.
T4transport 0.1.8 (2026-01-11)
- Changed
hdist() to histdist() for modality-specific computation.
imagebary() added for unregularized Wasserstein barycenter of images.
imagedist() added for the Wasserstein distance between two images.
imageinterp() added for Wasserstein interpolation between two images.
imagemed() added for unregularized Wasserstein median of images.
T4transport 0.1.7 (2025-12-22)
- Removed dependence on CVXR package.
T4transport 0.1.6
- API references restructured.
- Added a number of functions for histograms, including distance, barycenter, interpolation, and median.
- Added
img2measure() to extract a discrete measure from a gray-scale image matrix.
- New family of routines for Gromov-Wasserstein geometry,
gwdist() and gwbary(), added.
T4transport 0.1.5 (2025-11-13)
- Replaced
lpSolve package's EMD solver with Nicolas Bonneel's highly-optimized C library.
- Added functions for Procrustes-Wasserstein geometry:
pwdist() and pwbary().
T4transport 0.1.4
rbarygd() for a Riemannian gradient descent to compute the free-support barycenter is added.
T4transport 0.1.3 (2025-05-29)

- Two ad hoc median routines for images and histograms are removed.
T4transport 0.1.2 (2023-04-11)
gaussmed1d() and gaussmedpd() now fully respects the product manifold perspective.
gwdist() added for Sliced-Wasserstein distance computation.
