Time series analysis for ECG data compression
Hazem M. Abbas · 1999
This work presents a new electrocardiogram (ECG) data compression method. By differentiating the signal and using proper thresholding, the ECG is first segmented into a sequence of straight lines. The vertices of these lines are used to encode the signal. The decoding part works by applying the fast orthogonal search (FOS) method (Korenberg and Paarmann 1991) to reconstruct the original signal. Simulation results have demonstrated the efficiency of the algorithm.
