BiSPy : Bivariate Signal Processing with Python

BiSPy is an open-source python framework for processing bivariate signals. It supports our papers on time-frequency analysis [1], spectral analysis [2] and linear time-invariant filtering [3] of bivariate signals.

These papers contains theoretical results and several applications that can be reproduced with this toolbox.

This python toolbox is currently under development and is hosted on GitHub. If you encounter a bug or something unexpected please let me know by raising an issue on the project page.

Install from PyPi

Due to name conflict the available version on PyPi is named ``bispy-polar''. To install from PyPi, simply type

pip install bispy-polar

It will automatically install dependencies (see also below).

To get started, simply use

import bispy as bsp

Requirements

BiSPy works with python 3.5+.

Dependencies:

• NumPy
• SciPy
• Matplotlib
• numpy-quaternion

To install dependencies:

pip install numpy scipy matplotlib numpy-quaternion

numpy-quaternion add quaternion dtype support to numpy. Implementation by [moble]. Since this python toolbox relies extensively on this module, you can check out first the nice introduction here.
