Adaptive Mathematical Morphology for QRS Fiducial Points Detection in the ECG

Jean-Marc Vesin, Sasan Yazdani

Fixed structure Mathematical Morphology (MM) operators have been used to detect QRS complexes in the ECG. These schemes are limited by the arbitrary setting of threshold values. Our study aims at extracting QRS complex fiducial points using MM with an adap ...

Extension of FRI for modeling of electrocardiogram signals

Ali Hormati, Gilles Baechler

Recent work has developed a modeling method applicable to certain types of signals having a "finite rate of innovation" (FRI). Such signals contain a sparse collection of time- or frequency-limited pulses having a restricted set of allowable pulse shapes. ...
