The proposed dc equalization and complexity sorting preprocessing techniques improve 2-D ECG signal compression algorithms compared to existing methods.
May enhance ECG data handling efficiency; leaves open prospective clinical validation before practice change.
In this brief, we present new preprocessing techniques for electrocardiogram signals, namely, dc equalization and complexity sorting, which when applied can improve current 2-D compression algorithms. The experimental results with signals from the Massachusetts Institute of Technology - Beth Israel Hospital (MIT-BIH) database outperform the ones from many state-of-the-art schemes described in the literature.
