Region Contraction-Based Sparse Approach for Magnetocardiography Current Source Imaging
Reconstructing the cardiac current source and its imaging with magnetic field data measured by the superconducting quantum interference on the surface of the human thoracic cavity is a new technique for non-in...

Noninvasive Research on Cardiac Electrical Activity by Non-Gaussian Prior Bayesian Matching Pursuit
It is an important branch of biometrics security to obtain the cardiomagnetic signal non-invasively. In our study, the problem of sparse cardiac current source reconstruction is studied using Bayesian matching...

RVM for Recognition of QRS Complexes in Electrocardiogram
QRS complex is with significant use in electrocardiogram (ECG) components. This paper uses a special algorithm to recognize QRS complexes in the ECG, which is based on relevance vector machines (RVM). RVM is u...

A Sparse Decomposition Approach to Compressing Biomedical Signals
An approach of compressing biomedical signals was studied in this paper. First of all, we constructed an over-complete dictionary according to characters of compressing signals. Using the orthogonal matching p...
