Assessing indexes in the ECG data compression

本文描述ECG数据压缩算法评价中的各种数字指标，如相似性指标（CC、RMS、PRD等），误差指标（幅值误差、峰值误差等），压缩效率（压缩比、平均码率）、计算复杂性等，以及更具实际评判作用的视觉验证等方法。

This paper describes various numerical assessing indexes in evaluating algorithms for the ECG data compression, such as numerical indexes of similarity (CC, RMS, PRD). indexes of error (amplitude error, peak error),efficiency of compression (Compression Ratio, bit rate), computing complexity, and so on. It also involves visual inspection which is more important in assessing algorithms.
