Optical Flow Jetson Orin

[axnet]

I found that VPI dense optical flow only supports Xavier NVENC backend currently. And i need to implement in in Jetson Orin, is there a guide for this? to implement it in OFA hardware preferably or CUDA cores ?

Hi,

VPI dense optical flow is not available on Orin currently.
The OFA backend version is in our roadmap and will be supported in the near future.

Since OFA requires internal API, you will need to wait for our official support.
For CUDA implementation, you can check if OpenCV can meet your requirement:

Thanks.

Does the VPI that will be released only supports dense optical flow? If i’m planning to implement sparse optical flow will the released version of VPI allows the implementation of sparse optical flow using OFA backend.
