# FUGW on volumes

- [x] run `fugw` on volumetric images with euclidean distances
- [x] draft new example on low-resolution data
- [x] draft new example with `coarse_to_fine` on mid-resolution data
- [x] study if geodesic distances (computed with `dijkstra3d`) yield similar results
- [x] enable computing validation loss on validation features for each BCD step
- [x] enable computing custom loss on validation features for each BCD step
