Hi,

How can i use your framework to test on my own video data.

thanks for sharing your work, but could u pls. release more details...?
for example, i am repeating the work through the guidelines you gave in README, now i have the evaluation results of dual method of short-term, but i can't find your results to compare. I want to know if my results is wrong or not.

thanks a lot for that you have released the Common optical flow metrics (short-term), Tracking Accuracy (long-term), but only the digits, could u pls. release a little more estimate source code so i can check my evaluation results ?

forward to your reply, thanks!

For reference purposes, can your Arxiv paper link also be noted in the readme? The link is https://arxiv.org/abs/1811.07170 . Thanks.

？

In the section "Evaluation Framework"

The statement :
must be stored as /estimate/[mymethod]/images/IM01/frame_0000.flo

Should be updated as:
must be stored as /estimate/[mymethod]/IM01/frame_0000.flo

Gives file read error otherwise.

i view the file both in https://cn.overleaf.com and using TeXworks, but failed
the overleaf reported:

LaTeX Error: Environment table undefined.

You have created an environment (using \begin{…} and \end{…} commands) which is not recognized. Make sure you have included the required package for that environment in your preamble, and that the environment is spelled correctly.

error when using progressbar 2.5

run opticalflow_evaluate.py,

/usr/bin/python3.5 -u /home/xxx/CrowdFlow-master/opticalflow_evaluate.py /home/xxx/TUBCrowdFlow dual farneback plk

got error:

Traceback (most recent call last):
  File "/home/xxx/CrowdFlow-master/opticalflow_evaluate.py", line 92, in <module>
    main()
  File "/home/xxx/CrowdFlow-master/opticalflow_evaluate.py", line 74, in main
    bar.start(max_value=len(config_list) * len(parameter_list))
TypeError: start() got an unexpected keyword argument 'max_value'

Process finished with exit code 1

if edited the line 74#, replace max_value with maxval, still got error:

Traceback (most recent call last):
  File "/home/xxx/CrowdFlow-master/opticalflow_evaluate.py", line 92, in <module>
    main()

    bar.start(maxval=len(config_list) * len(parameter_list)) 
TypeError: start() got an unexpected keyword argument 'maxval'

this can be fixed by using progressbar 3.46.1 (tested)

hello, what's the requirement of running this project, i followed the README in ubuntu16.04 with opencv 4.1.1 but got error:

python3 opticalflow_estimate.py /home/xxx/dataset/middlebury/test/ dual farneback plk

Traceback (most recent call last):

excuse me, what's the meaning and difference between IM01 and IM01_hDyn ?
What's the "_hDyn" stands for (was that stands for dynamic? then what does the "_h" mean ) ?
...and so on. Could u pls. share more description info. of the dataset ?
