Successive partition zero coder for embedded lossless wavelet-based EGC signal coding [EGC read ECG]

Wavelets have emerged as powerful tools for signal coding. Wavelet transform is used to represent the signal to some other time-frequency representation better suited for detecting and removing redundancies. Successive partition zero coder (SPZC) for embedded loss less wavelet based ECG signal coding which use both horizontal and vertical bit scanning is proposed. Experimental results show that SPZC outperforms than other coders such as EZW, SPIHT, LZC, etc. in terms of coding efficiency by successive partition the wavelet coefficients in the space frequency domain. Proposed algorithm is significantly more efficient in compression and in computation than other coders exists in the literature.
