Questions about optical flow generation

[jonbakerfish]

Hi, as mentioned in README, the flow_i1, flow_i2, flow_i3 is generated by run_flows_video.py. However, it seems that the script does not provide a parameter to control the window size. To generate flow_i2 and flow_i3 which part of the code should we change?

Basically, you should change this line https://github.com/zhengqili/Neural-Scene-Flow-Fields/blob/main/nsff_scripts/run_flows_video.py#L354, to indicate the step size (the original script is step size one)
