T4transport 0.1.8
- 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
- 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
- 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
- Changed the structure of the package.
- Applied the
log-sum-exp trick for numerical stability
to the entropic regularization solver.
rbary23L() added for simple free-support Wasserstein
barycenter computation.- Two ad hoc median routines for images and histograms are
removed.
T4transport 0.1.2
gaussmed1d() and gaussmedpd() now fully
respects the product manifold perspective.gwdist() added for Sliced-Wasserstein distance
computation.
T4transport 0.1.1
- Support for special types of data. See the reference for more
details.
T4transport 0.1.0

NEWS.md file to track changes to the
package.
- Initial release.
