| 摘 要： | 提出了基于小波变换的心电信号准无损压缩算法。在对原始信号进行一级小波分解的基础上，根据高频分量和低频分量所占位数的不同分别进行无损压缩。实验结果表明该方法失真度非常小，而且算法简单，运算速度快。

| Abstract: | A wavelet-based electrocardiogram data semi-lossless compression algorithm was proposed in this paper.The ECG signal was decomposed once by using the discrete wavelet transform.The different lossless compression algorithms was applied for the coefficients of the detail subband and the approximation subband.Our experimental results demonstrat that this is an efficient ECG compression method with very low degree of distortion and high operation speed. |
