processing speed of python version

[jahwanoh]

Hi,
First of all, thank you for sharing this code.
I tried with python version with high resolution video (4096x554) and it performs very slowly (4 fps).
Processing speed for the video is not a target of this paper but is there any suggestion how to improve processing speed?
I will try to search for how to use gpu with matrix operation because it seems numpy operations took much of the time.

Hi,

You can check this PR with an optimized Python version. It says it works 20X faster. I will review and merge it into the master branch soon, but just in case you are in a hurry.
