ECG signal processing

The research investigated to compress ECG signals using JPEG2000. Also proposed is a method of ECG signal de-noising based on Hilbert-Huang transform. This method uses empirical mode decomposition to decompose the signal into several intrinsic mode functions (IMFs) and then the noisy IMFs are removed by using soft-threshold method.

In this paper, we introduce VPNet, a novel model-driven neural network architecture based on variable projection (VP). Applying VP operators to neural networks results in learnable features, interpretable parameters, and compact network structures. This paper discusses the motivation and mathematical background of VPNet and presents experiments.

In this paper, a report is made on an application of the mentioned capability of wavelet transform for grasping subtle changes and discontinuities in electrocardiogram (ECG) signals. From the signal processing point of view, it shows that the diagnostic of ECG signals is carried out by excluding any recognised abnormality as singular points or irregular structures.

In order to address these issues, we have attempted to detail many of the key relevant advances in signal processing. Chapter 1 describes the physiological background and the specific autonomic mechanisms which regulate the beat-to-beat changes of timing and morphology in the ECG, together with the cause and effect of breakdowns in this mechanism. Chapter 2 presents an overview of the primary issues that should be taken into account when designing an ECG collection system.
