Pre-processing methods

Pre-processing methods

 

Pre-processing consists in a wide variety of algorithms. Basically, the main idea of pre-processing has to be shown as a previous step for the further analysis. These previous tasks can be: clean a certain contamination in the signal such as muscular noise or power line noise, detection of beats (in the case of ECG recordings), and so on. In the current version BioSigBrowser has available the following pre-processing modules:

  • Filters
  • ECG detector/delineator
  • Heart beat classifier
  • Other ECG leads (by linear combination of the recorded ones)
  • PPG Artefact detector
  • PPG Pulse detector
  • Principal Component Analysis (PCA)
  • Independent Component Analysis (ICA)
  • Periodic Component Analysis (pCA)
  • Segment Karhunen Loewe Transform
  • Ectopic beat detection
  • Series generation
  • Events generation by segmentation
