Functions

function BVP_feat_extr (in BVPSignal, in varargin)
 

Detailed Description

Computes BVP features.

Parameters
BVPsignalthe BVP signal.
vararginyou can choose which features to extract (see featureSelector)
       the list of available features is:
      - mean_: averaged BVP - ralated to blood pressure
      - HRV: heart rate variability calculated based on the standard
      deviation IBI differences
      - meanIBI: mean heart rate (beat per minute)
      - MSE: Multi-Scale Entropy at 5 levels 1-5
      - sp0001: spectral power in 0.0-0.1Hz band
      - sp0102: spectral power in 0.1-2.1Hz band
      - sp0203: spectral power in 0.2-3.1Hz band
      - sp0304: spectral power in 0.3-4.1Hz band
      - sp_energyRatio: spectral power ratio between 0.0-0.08Hz and
      0.15-0.5Hz bands
      - tachogram_LF: Tachogram's low freqneucy spectral content
      <0.08Hz
      - tachogram_MF: Tachogram's medium freqneucy spectral content
      0.08Hz> and <0.15Hz
      - tachogram_HF: Tachogram's high freqneucy spectral content
      0.15Hz> and <0.5Hz
      - tachogram_energy_ratio: energu ratio tachogram_MFSP/(tachogram_HSP+tachogram_LFSP)

Return values
BVP_featslist of features values
BVP_feats_namesnames of the computed features (it is good pratice to check this vector since the order of requested features can be different than the requested one)
Bulkif the input to the function is a Bulk than the Bulk is returned with the updated BVP signal, including IBI. Otherwise NaN is returned
