This package is a simple Python wrapper to an open-source Optical Flow estimator based on the works by Horn & Schunck:
@article{Horn_Schunck_1981,
author = {Horn, B. K. P. and Schunck, B. G.},
title = {Determining optical flow},
year = {1981},
booktitle = {Artificial Intelligence},
volume = {17},
pages = {185--203},
}
The implementation is purely based on Bob:
