Özet
This paper describes a prototype waveform interpolation approach for efficient electrocardiogram (ECG) compression. The algorithm is based on the interpolation of discrete cosine transform coefficients of the prototypes extracted from the linear predictive residuals of ECG frames. The proposed algorithm therefore exploits the inter-cycle and intra-cycle redundancies that are present in ECG signal. The results reveal that linear predictive based prototype waveform interpolation is suitable for ECG compression and unquantized prototypes provided percentage root mean square difference (PRD) values below 10%.
