摘要
该文提出了一种关于心电信号高效保真的压缩算法,使用了jpeg2000算法对数据进行了编码压缩,改进了其它算法在信号数据二维转换时带来的数据部分丢失的缺陷,算法流程包括六个部分:QRS识别、信号预测判别分组、二维转换、信号压缩编码、恢复原信号和算法评估。测评采用了常用的心电性能指标评估标准,结果显示其压缩性能优于很多算法,并且为诊断保留了较多的心电信号的有用信息。
The paper proposes an efficient ECG compression algorithm with high fidelity.It encodes the data with jpeg2000 algorithm and improve on data loss when the signal data are transformed to 2-dimesion.The algorithm contains: QRS recognition,signal detecting and classification,2-dimesion transform,signal compression encoding,signal rebuilding and algorithm evaluation.Compare with universal evaluation criterion of electrocardiosignal items,its algorithm is better than others and keep most information for diagnosis.
