One question about training on FlyingThings3D #21

Closed yxqlwl closed 7 years ago

yxqlwl commented 7 years ago

Hi, When training on FlyingThings3D, should we use the flow files in folder .../into_future/left?

nikolausmayer commented 7 years ago

Hi,

the choices into_future/into_past and left/right should not matter in practice. There are no useful priors that distinguish any one from the others.

We used into_future/left, but without a particular reason.

Best, Nikolaus

Thank you!

Hi, One more related question about this topic: In the things3D training set, I think (taking an example):

 "optical_flow/TRAIN/A/0000/into_future/left/OpticalFlowIntoFuture_0007_L.pfm" 
 corresponds to the following image pair:

 "frames_cleanpass/TRAIN/A/0000/left/0007.png"
 "frames_cleanpass/TRAIN/A/0000/left/0008.png"

 instead of:

 "frames_cleanpass/TRAIN/A/0000/left/0007.png"
 "frames_cleanpass/TRAIN/A/0000/right/0007.png"

Is that correct? Best ViJay
