Hi,
Thanks for your feedback and also sorry for my previous unclear reply.
vx_: Khronos OpenVX API(Nvidia optimized), please find document to check detail implementation. (mentioned in #2)
nvx_: Nvidia extension API, only GPU implementation is available.
nvxcu_*: Low-level CUDA API, only GPU implementation is available.
Ideally, target should be switched by vxSetNodeTarget.
But we found this function works abnomarllay when target string set to “CPU”.
We are checking this issue internally. Will update information to you later.
Thanks.
