| 摘 要： | 本文介绍了中值滤波、曲线拟合、高通滤波、形态学处理等几种不同的去心电基线漂移算法的实现。通过RCMIT／BIH数据库中36份数据的比较，发现在处理效果上，中值滤波和基于形态学的方法处理效果都比较好，形态学结果比中值滤波的结果在正方向上略有偏移。高通滤波的方法对平整的S-T段的抬升很明显，而曲线拟合在处理较大的漂移时，效果就不明显了。 |

| Abstract: | The paper introduce the implement of several kinds of arithmetic to take base-line excursion from ECG signal,including median filtering,curve fitting,high pass filtering and morphologic process.After comparing the processing result of 36 shares of MIT/BIH ECG data,we found that median filtering and morphologic process is better than else,the morphologic process has a little offset in positive direction comparing with median filtering;high pass filtering is obvious in raising smooth S-T segment;The result is unobvious when processing high base-line excursion using curve fitting. |
