Project description
ppg
ppg preprocessing (e.g., ppg> spectogram, bandpass, moving average)
ALL in One: Simple PPG preprocessing
Usage
Installation
pip install ppg-pre
python usage
from ppg_pre import get_ppg_sample
x = get_ppg_sample() # get sample ppg data
from ppg_pre import ppg2specgram
x = ppg2specgram(x) # u can get the spectrogram data
Function
ppg2specgram function has the following processing.
- interpolate
- bandpass (0.5~10 Hz)
- moving average (30 taps)
- z-score normalization (mean:47, std:15)
- spectrogram
Visualization
from matplotlib import pyplot as plt
from ppg_pre import get_ppg_sample
x = get_ppg_sample()
plt.plot(x[12000:15000])
