心电信号去噪的数学形态学滤波器
Morphological filter to remove power-line interference and baseline wander in electrocardiogram
摘要
Abstract
To explore and verify a filter design based on mathematical morphology for removal of power-line interference and baseline wander in electrocardiogram (ECG). Based on signal filtering principle of mathematical morphology, an adaptive threshold ECG de-noising algorithm is given;the values of 3σ statistical criterion on adaptive threshold ECG denoising are discussed. Then the ECGs with common power-line interference and the ECGs with baseline wander are researched respectively by means of this improved algorithm. The analyzed ECG signals are chosen from MIT-BIH arrhythmia database. The simulation results show that the proposed filter can remove the baseline wander and power-line interference in ECG effectively; The method has a better performance in ECG denoising, and it supplies a potential tool in real time processing of one-dimension biomedical signals.关键词
