2-D Compression of ECG Signals Using ROI Mask and Conditional Entropy Coding
Boqiang Huang, Yuanyuan Wang, Jianhua Chen · IEEE Transactions on Biomedical Engineering · 2008
A novel 2-D compression scheme of ECG signals is proposed, which employs 1-D discrete wavelet transform, the region of interest mask, and the conditional entropy coding based on context models. Experimental results on records selected from the Massachusetts Institute of Technology-Beth Israel Hospital arrhythmia database show that the proposed method outperforms some existing compression schemes.
