Cuda implementation of AKAZE #1757

Open solonovamax opened 1 month ago

solonovamax commented 1 month ago

It would be nice if a cuda implementation of AKAZE could be added.

According to the comment on the src/aliceVision/feature/akaze/AKAZE.hpp, the implementation is taken from pablofdezalc/akaze.

going to that page, they list the following under an "other implementations" header:

You can try the CUDA A-KAZE implementation from Niklas Bergström: nbergst/akaze

There is also a very fast CPU A-KAZE version from Hideaki Suzuki h2suzuki/fast_akaze

Since those are all licensed under a BSD-3-Clause license, would it perhaps be possible to get the cuda version (and possible the "fast cpu" version) added to alicevision?

I agree, it would be great to have more cuda acceleration. You are welcome to contribute the implementation :) If you are interested and want to get started, feel free to ask, the core devs are happy to give you some pointers.

I'm not a c++ dev myself, which is why I didn't offer to do it. I don't think that c++ with archaic cuda code optimized for performance is the best place to get started with c++. but if I ever get around to learning c++, and this issue is still open, I may come back to it later

You are also welcome to help out with https://github.com/alicevision/Meshroom which is mostly Python/QT based. And if you´d like to tinker around a little, there is https://github.com/alicevision/MeshroomResearch. A plugin system is wip https://github.com/alicevision/Meshroom/pull/2407 to lower the contribution barrier to add new functionality.
