Wavelet-Domain L  ∞ -Constrained Two-Stage Near-Lossless EEG Coder
Published in Springer Berlin Heidelberg
Volume: 70
Pages: 76 - 80

In this paper, a two-stage coder based near-lossless compression of Electroencephalogram (EEG) is discussed. It consists of wavelet based lossy coding layer (until bitplane n d ) followed by entropy coding of the wavelet domain residuals. L -error bound is fixed in wavelet domain and the corresponding time-domain absolute error variation is studied. Studies show that intermediate demarcating bit-planes (n d ) register a higher compression and gives a nearly constant time-domain error. Both the normal and epileptic EEG registered a comparable compression performance.
