Compression of Digital Biomedical Signals / Tapio Gro¨nfors, Martti Juhola
2008
A variety of lossy compression approaches are available. The main methods are[2] scalar and vector quantization with multiple variations on the theme, differential encoding, transform methods, subband coding, and wavelet-based methods. Differential encoding does not provide as high compression as quantization methods, but it is very simple and suited to implementation for signal-like data.
