Hello,<br>
<br>
Thanks for the excellent initiative and work done so far on this
topic !<br>
Reading the slides, it is *very* promising.<br>
I particularly liked the part about the factories where legacy code
will be gpu-enabled automatically.<br>
<br>
One question hit my mind : will the framework support
itk::VectorImage, and not only itk::Image ?<br>
At least, will it have the possibility to be extended for this in
the (hopefully near) future ?<br>
<br>
Best regards,<br>
Julien<br>
<br>

<div>The bulk of the GPU support is not in the main ITK repository
yet. 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. Plus an outside group has
implemented the RecursiveGaussian filter in this architecture.</div>
