基于组合形态滤波与自适应广义形态滤波的ECG去噪算法

针对ECG信号中存在的基线漂移和高频干扰,提出了一种传统线性组合形态滤波与自适应广义形态滤波相结合的新的去噪算法。该算法首先采用传统线性组合形态滤波器滤除基线漂移,然后将无基漂的信号送入采用不同结构元素级联而成的自适应广义形态滤波器滤除高频干扰,最后得到无噪声的ECG信号。结果验证了本文算法的有效性。

An ECG Filter Algorithm Based on the Combined Morphological Filter and Adaptive Generalized Morphological Filter

Since there are some baseline drift and high-frequency noises in ECG signals,a new algorithm for ECG denoising was proposed on the basis of the traditional linear combinations of morphological filtering approach and adaptive generalized morphological filtering approach.After the baseline drift of the incoming ECG signals is removed with the traditional linear combinations of morphological filter and the high-frequency noise is filtered with adaptive generalized morphological filter,and then the clean ECG si...
