Sorry to disturb. I'm having a confusion about the code of ABME. Specifically, why multiply the optical flow by 20 after upsamplling it 4 times using bilinear interpolation? Thanks a lot for your help.

I understand now it's a result of accumulation of several multipling operation. But why the first multiplication is by 0.625 after upsampling the flow 2 times using a deconv?
