Thanks for getting in touch!

Nathan Faggian has done some work towards registration in pyimreg, and
what we discovered is that it is fairly hard to come up with a good
API.  Perhaps you can have a look at that code and give us your
feedback?  Registration would be a very useful feature to have in
skimage.

Perhaps we could start with something simple: compare Harris features
with a robust matching algorithm such as RANSAC to find alignment with
a simple error measure (there is a PR for RANSAC by @ahojnnes).  Once
aligned, perform Laplacian or other blending.  If that works, one can
focus on adding other feature detectors, multi-resolution matching,
different error measures, optimization based approaches, etc.  There
may be some code in https://github.com/stefanv/supreme that we can
re-use, or we can simply start from scratch.

Eventually, I am also interested in non-rigid registration,
registration of voxel data, etc.

Registration / blending is an immense topic that can very easily cover
an entire GSoC.
