Recommended arguments for optical flow computation

[vguptai]

Hi @feichtenhofer,

Thanks for sharing this amazing work. For my work, I also wanted to calculate flow for Olympic Sports dataset also by using the gpu_flow library that you have shared. Can you please share with me the recommended values for the following options, so that the flow are coherent with the precomputed flows that you shared.

1. skip
2. stride
3. clipFlow
4. MIN_SZ
5. OUT_SZ

I would be happy to share the pre-computed flow so that others can also benefit and save some time.
