摘要: The optimization of the parameters a uniform scalar dead zone quantizer used in wavelet-based ECG data compression scheme is presented. Two quantization parameters: threshold T and step size Δ are optimized for target bit rate through particle swarm algorithm. Experiment results on several records from MIT-BIH arrhythmia database show that produces improved performance.
