About the algorithm of Turing Optical Flow

I hope to evaluate Turing Optical Flow using NVIDIA Optical Flow SDK.
But, I could not find information of the algorithm of Turing Optical Flow.

  • https://developer.nvidia.com/opticalflow-sdk
  • https://devblogs.nvidia.com/an-introduction-to-the-nvidia-optical-flow-sdk/
  • The optical flow hardware in Turing GPUs uses sophisticated algorithms to yield highly accurate flow vectors.
    

    Could you publish the information it as much as possible?
