Hi. Thank you for replying so soon.

Perhaps we could start with something simple

Sure, that is a good prototype, and, I think, it can be implemented in the following couple of days. Than I should choose some subset of possible improvements and turn it into a full-fledged project proposal with timeline and milestones to submit to Google.

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

Judging by the adjastent thread, 3d algorithms are highly desirable for scikit-image, so they should be at least kept in mind when designing the project. As for the state of the art topics in general, it would be great to continue GSoC as a research project during the term. вторник, 30 апреля 2013 г., 4:33:48 UTC+4 пользователь Stefan van der Walt написал:

Thanks for getting in touch!

What do you think about such project? I guess, it's rather ambitious, yet it is diverse, interesting and will keep me from slacking. If some of the mentioned ideas get separate projects, they can be adopted during summer.

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.
