Abstract :
The paper presents a new algorithm for lossless ECG compression using lifting wavelet transform. The transform is implemented in its integers to integers version, and thus quantization of wavelet coefficients and rounding of errors are avoided. A new adaptation method for the wavelet lifting transform is presented. The efficiency of adaptive lifting transform is compared with DPCM coding and S+P transform.
