How long it takes to compute optical flow for UCF101 dataset? #7

Hi, I want to compute optical flow for UCF101 datasets. Do you remember how long it takes? Thanks for your help.

It takes ~0.2 seconds to extract 1 frame with GPU implementation of Brox optical flow. As far as I remember, I parallelized on 2 GPUs and extracted in ~1 day the UCF101 dataset. Now, you can use more recent flow algorithms.
