利用DCT分量差值压缩ECG数据的方法

A New Compression Method For ECG Data

由于心脏活动的有序性和各心电活动周期波形的相似性 ,各心电活动周期波形的 DCT(离散时间余弦变换 )分量也具有一定的相似性。根据这一特点 ,本文提出了在首先使用 DCT压缩心电图 ( ECG)数据的基础上 ,进一步利用各 ECG周期的

Due to the regularity of activity of the heart and similarity among each period of ECG signal, there is high correlation between DCT coefficients of every two frames of ECG data. Using this characteristic, we present a Compression method for ECG data in this paper, by which we can get a higher compression ratio(CR) than the compression method just via DCT does.
