Find Good Optical Flow Algorithm #5

Closed ahmedbilal closed 5 years ago

ahmedbilal commented 5 years ago

We initially tested Farneback Optical Flow shipped with OpenCV. But, you noticed that its results are not very good. So, I tested pathak22's pyflow. Its results are little better but it is very slow i.e it takes 10-15 seconds on My CPU (i7-3840QM) and even more on Google Colaboratory's CPU. So, it is infeasible to find optical flow using this algorithm. Frame 1 Imgur

The purpose of this issue is to notify all of you to find some good Optical Flow algorithm that can run on either our local machine or Google Colab.

Please test it on your machine or Google Colab before suggesting.

I tried it on Google Colab but unfortunately Google Colab doesn't support Docker (it doesn't allow docker daemon to run). So, I am trying it on my laptop (it is large download and whole process is taking a lot of time). So, hope it would work.

Tried to run on my Laptop but error occurred. More Details
