🎉 New feature: You can now compute the activity index for ACC signals!
(Check PR #14)

🎊 New feature: We just added new functions for EDA feature extraction and
decomposition! (Check PR #15)

BioSPPy - Biosignal Processing in Python

A toolbox for biosignal processing written in Python.

The toolbox bundles together various signal processing and pattern recognition methods geared towards the analysis of biosignals.

Highlights:

• Support for various biosignals: BVP, ECG, EDA, EEG, EMG, PCG, PPG, Respiration
• Signal analysis primitives: filtering, frequency analysis
• Clustering
• Biometrics

Documentation can be found at: http://biosppy.readthedocs.org/

Installation

Installation can be easily done with pip:

$ pip install biosppy

Simple Example

The code below loads an ECG signal from the examples folder, filters it, performs R-peak detection, and computes the instantaneous heart rate.

from biosppy import storage
from biosppy.signals import ecg

# load raw ECG signal
signal, mdata = storage.load_txt('./examples/ecg.txt')

# process it and plot
out = ecg.ecg(signal=signal, sampling_rate=1000., show=True)

This should produce a plot similar to the one below.
