This method is meant for working with multiple images where something has significantly changed in a non-linear way. E.g. think of trying to produce a deformation map of clay that you've squeezed by taking lots of photographs during squeezing. You can also use it in the reverse sense and align multiple images where things are changing in complex ways. The fact that inverts for / is constrained by a continuous velocity field has some nice advantages compared to other methods. Or that's my bad summary of it, anyway.
As someone who uses this general class of methods pretty frequently (albeit in satellite imagery), I'm very curious to dig into this! Looks like a very understandable set of implementations!
