【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.更多还原
