imregister does not support GPU unfortunately. Are there any workarounds? I have hundreds of millions of images to register and any little acceleration will be significant. These images should at least be translationally registered. Rotations, resize and deformations can be ignored if necessary.

If you only need to register translation, you can use normxcorr2() which is GPU-supported
