GPU Support

It seems like this is the right kind of application which a GPU can speed up. Have you considered this?

I use 3rd party libs for computationally intensive operations - numpy and for the DFT, pyfftw is used if it is available. If you know 3rd party libs that can do the job faster, let me know. I consider imreg_dft a high-level project that should not contain any low-level code since it doesn't do anything really special under the hood. However, some of the algorithms (esp. the tiling one) can be improved substantially in terms of performance.

Thanks for your comment. I'll try to switch in a GPU implementation of the FFT functions and benchmark it.

hi, have you guys implemented a GPU version of this algorithm? It will be very helpful.

Any update on this? GPU implementation would be great.
