The proposed WEWPRDs criterion improves rate-distortion performance for SPIHT-based ECG coding in noisy environments compared to existing criteria.
An effective quality-controlled set partitioning in hierarchical trees (SPIHT)-based ECG coding strategy under noise environments is proposed using a wavelet-energy based weighted percentage root mean square difference (WEWPRDs) criterion. This criterion is subjectively meaningful and leads to a better measure of rate-distortion (R-D) performance. Experiments on several noisy records from the MIT-BIH arrhythmia (mita) database show that the proposed strategy outperforms PRD and wavelet-based weighted PRDws (WWPRDs) measurement-criteria-based strategies.

Manikandan et al. (2008) studied Arrhythmia (ECG records). Quality-controlled SPIHT-based ECG coding strategy using WEWPRDs criterion vs. PRD and wavelet-based weighted PRDws (WWPRDs) measurement-criteria-based strategies was evaluated on Rate-distortion (R-D) performance. The proposed quality-controlled SPIHT-based ECG coding strategy using WEWPRDs criterion outperformed PRD and WWPRDs measurement-criteria-based strategies on noisy records from the MIT-BIH database.
