There are GPU-Alpha and GPU-Beta branches on individual github accounts for the very brave but I do recommend using it yet. The GPU-Alpha is reported to work on some Windows platforms and GPU-Beta is reported to work on some Mac platforms (but not vice versa).</div><div><br></div><div>The GPU support will include exemplar implementations of a variety of filter types which the community can use to base GPU implementations of other filters. These family of filters will include UnaryFunctor style filter, linear neighborhood filters, diffusion, demons style registration.
