Vector quantization of ECG wavelet coefficients
Kanwaldip Singh Anant, Farid Dowla, Garry Rodrigue · IEEE Signal Processing Letters · 1995
An improved wavelet compression algorithm for ECG signals has been developed with the use of vector quantization on wavelet coefficients. Vector quantization on scales of long duration and low dynamic range retains feature integrity of the ECG with a very low bit-per-sample rate. Preliminary results indicate that the proposed method excels over standard techniques for high fidelity compression.>
