greedypy's Issues

Smoothness of the deformation fields using the greedy method

Hey I was testing your package on some simple images
Screenshot 2022-01-03 at 13 17 33. After running the algorithm i checked out the warp field

And it looks something like this. I know that the greedy method does not guarantee that there should be no folds in the grid do you think this is the expected result.

I tried to implement the greedy method using SyN in jax. Although it is far from perfect right now the results look more reasonable especially the warping grid

But thanks for this package. This and pyrpl have really helped me with the more obscure bits such as resampling etc of displacement fields.
