There isn't currently a GPU implementation, but you can use multiple threads by setting the environment variable ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS
. This variable should be set before importing ants.
@cookpa Thank you. I have tried that and the registration is faster than before. Will there be any GPU implementation in future?
Hi there - GPU implementation of standard ANTs registration is not on the roadmap. The best bet would be to wait for a deep learning-based implementation of registration to come out, which is something that is being generally worked on by the community.
Is your feature request related to a problem? Please describe. I am currently using ants SYNRA registration to register a ct image to a template. This registration worked for most of the cases and I would like to use this one. But it takes a lot of time. Is there any possible way which I could use to increase the speed of registration without much affecting the results.
Describe the solution you'd like I would like to know if I can run the registration on GPU.
Describe alternatives you've considered If there is no GPU support, I would to run the registration in parallel on multiple threads. If there is any parameters that I need to edit so that the speed of the registration is faster and the result is not much affected. That would be great
