Any documentation on optixOpticalFlow?

[user131777]

Hello,
I was wondering if there was any documentation describing how the code in optixOpticalFlow SDK example works? Is there a paper, etc?

Thanks.

Does this help answering your question?
https://developer.nvidia.com/opticalflow-sdk
Follow the Resources links at the bottom of that page as well.

Documentation: https://docs.nvidia.com/video-technologies/optical-flow-sdk/index.html

There is also a developer forum covering that Optical Flow SDK in this same Visualization section.

The OptiX SDK example’s source code just uses the CUDA API in that.
Please read through the source code to see how it loads the necessary DLL from the driver and fetches the entry point functions used later.

(Note that this is not the way the flow images in the motion denoiser example data folder have been generated!
These come from a renderer which knows about camera and object motion and generated the perfect motion flow images.)
