Need for compressing the label by 20

[adhara123007]

Dear Sir,

"We scale the ground truth flow by 20 and downsample it to obtain the supervision signals at different levels" is written in your paper . What was the need for scaling the ground truth?

Thanks and Regards, A.

@adhara123007 because otherwise the magnitude of the flow is too big (and diverse in scale). This is a similar strategy in the flownet paper.

@jrenzhile "Scale" here you mean scale down (/20) instead of scale up (*20) Am I correct?
