alignment API #66

Open alisterburt opened 4 months ago

alisterburt commented 4 months ago

Do we want a simple, general purpos rigid body image alignment API? Feels like it would be a useful thing to have in the toolbox

grid search vs gradient descent style optimisation? both?

shahpnmlab commented 4 months ago

how about gradient desecent guided grid search? or vice versa?

alisterburt commented 4 months ago

@shahpnmlab I'm not sure how that would work...

I have my own repository for a prototype of projection matching in 2D using libtilt. Happy to share it once it is a bit cleaner. We could use it as a prototype before implementing other stuff. Extending it to 3D should be trivial.

Perhaps doing global search as grid search, and then local search as gradient descent? Or perhaps having interleaving steps of grid_search, local_search
