Do we plan to use GPU operation like https://docs.nvidia.com/cuda/npp/group__nv12torgb.html#details? |
|
@bhack Yes it is definitely on the roadmap. In fact in last month's meeting we also discussed about the possible MLIR integration into tensorflow-io. Will need to do some exploration work first, though. |
Yes this is super interesting also for other image processing ops that are landing in Addons PRs. Can you share something more about this topic? |
