Is computing the TV-L1 optical flow a computationally heavy task?
My system has 8GB RAM and the Processors are on fire, while the code runs.

I do not find any warped version to fight for camera motion. like warp TVL1 flow. Are you going to support that?

The features of the photos I got using the TVL1 method are not obvious.Below is an optical flow feature that I got using casmeii's EP02-01f.How to change to get obvious optical photo?

According to the code, there are 2 folders inside the "UCF101/tvl1_flow/" directory, "u" and "v".
When we download the zip file from [this](https://github.com/feichtenhofer/twostreamfusion) mentioned…

When i run the extract_frames_flows.py to extract flow and frames , it show me

Hi, I would like to know how to preprocess the kinetics-400 for reproducing the results. I found that extracting tvl1 flow before rescale the rgb images leads to worse flow recognition accuracy.
So,…

It looks to me that when S2P aligns images it does not have the concept that sometimes in the left image there is valid intensity data, but the right image lacks data at that location, which happens …

All the requirements were successfully installed and there is no error occurred.
However, when I use denseflow to extract frames from videos, specifically the HMDB-51 datasets, such error appears:…

do I need to normalize RGB images to [0,1] from [0,255] before calculate optical flow?
I will follow the code here. https://github.com/opencv/opencv/blob/master/samples/gpu/optical_flow.cpp
And 'd_…
