Abstract:There has been an increasing interest in the study of the automated physiological disease detection in recent years. It could greatly reduce the burden of traditional visual inspection of medical images (e.g. EEG, ECG, MRI, X-ray etc.) by experienced physicians and deliver diagnostic services at lower cost. Commonly, it is a kind of pattern recognition problems and how to design an appropriate feature extraction method is recognized to be crucial in the successful realization. In this talk, focusing on two physiological disorders: epilepsy and atrial fibrillation (AF), we mainly introduce the automated seizure detection based on EEG and AF detection based on ECG. We first systematically introduce the background and development of seizure and AF detection methods respectively; And then, some novel EEG and ECG feature extraction methods we proposed are presented, which can be categorized into nonlinear-similarity based feature, nonlinear-interdependency based feature and nonlinear-complexity based feature; Finally, our main directions in the research of medical data analysis and neural mass modeling are given.
