Low dimension/moderate bit rate vector quantizers for the Laplace source
Peter F. Swaszek · Journal of Media Literacy Education · 1990
Summary form only given. An unrestricted vector quantizer (VQ) has been obtained for the independent Laplace source, a source model useful for speech and image coding. The VQ is based on Helmert's transformation. Asymptotic performance and design results have been reviewed. Fischer's pyramid vector quantizer has been shown to be a special case of the present VQ; low-dimension results for the PVQ have been derived.
