Introduction

PyMO is a python library for machine learning research on motion capture data. It is designed on top of scikit-learn, pandas, and numpy.

I'm developing this library as a part of my Ph.D. research in an effort to streamline and fascilitate the prepration and feature extraction methods often used with motion capture data in the literature. Currently, the library is highly experimental and everything is subject to change :)
