- 基于小波变换的ECG信号去噪系统设计,在信号采集时,身体的任一微小运动都会产生“基线漂移”,这是一种低频干扰,同时,由于肌电的存在又产生了高频的肌电噪声,由于空间电磁场的存在又使心电信号中混有50Hz的工频干扰。这些噪声不去除,就会影响下一步的信号处理。 综合运用数字信号处理的理论知识进行生物医学信号增强系统设计,实现ECG信号的去噪,从而加深对小波变换及其应用的理解,建立概念多分辨分析的概念,加深理解信号增强的原理、方法和步骤。本设计的主要内容是设计一个基于小波变换的ECG信号去噪系统,

- ,对掌纹图像去噪主要采用低通滤波方法或邻域平均滤波方法,这两种方法可以有效地抑制噪声,但同时也滤除了一些边缘信息,而且还会发生一定程度的边缘模糊现象。因此这两种方法适合于提取掌纹中的主线(掌纹中最粗最长的若干条)特征,而不适合于需要保留更多边缘信息的特征提取。小波变换是目前比较流行的一种信号处理方法。-Palmprint image denoising using low-pass filtering method or the neighborhood average filter metho
