Welcome to biopeaks, a straightforward graphical user interface for feature extraction from electrocardiogram (ECG), photoplethysmogram (PPG) and breathing biosignals.
It processes these biosignals semi-automatically with sensible defaults and offers the following functionality:
- processes files in the open biosignal formats EDF, OpenSignals (Bitalino) as well as plain text files (.txt, .csv, .tsv)
- interactive biosignal visualization
- biosignal segmentation
- benchmarked, automatic extrema detection (R-peaks in ECG, systolic peaks in PPG, exhalation troughs and inhalation peaks in breathing signals) with signal-specific, sensible defaults
- automatic state-of-the-art artifact correction for ECG and PPG extrema
- manual editing of extrema
- extraction of instantaneous features: (heart- or breathing-) rate and period, as well as breathing amplitude
- .csv export of extrema and instantaneous features for further analysis (e.g., heart rate variability)
- automatic analysis of multiple files (batch processing)
