Diagnostic Quality Assessment for Low-Dimensional ECG Representations
Péter Kovács, Carl Böck, Thomas Tschoellitsch +2
There have been several attempts to quantify the diagnostic distortion caused by algorithms that perform low-dimensional electrocardiogram (ECG) representation. However, there is n…
ECG Beat Representation and Delineation by means of Variable Projection
Carl Böck, Péter Kovács, Pablo Laguna +2
The electrocardiogram (ECG) follows a characteristic shape, which has led to the development of several mathematical models for extracting clinically important information. Our mai…
Nonlinear least-squares spline fitting with variable knots
Péter Kovács, Andrea M. Fekete
In this paper, we present a nonlinear least-squares fitting algorithm using B-splines with free knots. Since its performance strongly depends on the initial estimation of the free…
Generalized Rational Variable Projection With Application in ECG Compression
Péter Kovács, Sándor Fridli, Ferenc Schipp
In this paper we develop an adaptive transform-domain technique based on rational function systems. It is of general importance in several areas of signal theory, including filter…
