摘要
该文简单介绍了胃电图 (EGG)以及小波的多分辨率分析原理和方法 ,并把小波分析运用到胃电图的信号处理中 ,对去噪、抽取特征参数、简化信息分析作了实验 ,使EGG在临床诊断中更具实际意义。
In this paper, we give a brief overview to multiresolution signal decomposition based on wavelet transform and the features of EGG. The application of wavelet multiresolution analysis to EGG signal analysis is presented. Some experiments are done to reduce noises and extract features of EGG, it is proved that this is an easier and effective way to do EGG analysis.
