摘要

介绍了利用小波变换和自适应分形插值方法对心电信号进行数据压缩的方法。该方法通过小波变换后的分形插值参数表示任意范围的心电信号。采用MIT/BIH数据库对算法进行评价。以相对较低的均方根差(PRD)实现高压缩比(CR)。

ECG data compression using wavelet and fractal interpolation

This paper represents the data compression for ECG signals using the wavelet and adaptive fractal interpolation method. The method represents any range of ECG signal by fractal interpolation parameters after wavelet transform. The suggested algorithm was evaluate using MIT/BIH database. A high compression ratio (CR) is achieved with a relatively low percent rms difference (PRD).
