0.6.0
Add low-level functions for stationary velocity field based diffeomorphic spatial transforms.
- Modify
mi_loss()
to allow use ofnum_samples
to limit maximum number when using asample_ratio
(#121). - Ensure Gaussian kernel tensor is 1-dimensional even when
sigma=0
(#122). - Fix
compose_flows()
to compute composite displacement field (#128, #129). - Add
compose_svfs()
to compose velocity fields using Baker-Campbell-Hausdorff (BCH) formula (#129, #130). - Add
lie_bracket()
of vector fields which is required for BCH formula (#129). - Add
logv()
, the inverse map ofexpv()
, based on the algorithm proposed by Bossa & Olsom (2008) (#131). - Switch from
.vscode/
folder todeepali.code-workspace
file (#123).
