On the amount of statistical side information required for lossy data compression

N Merhav, J Ziv - IEEE Transactions on Information Theory, 1997 - ieeexplore.ieee.org
Consider a vector quantizer that is equipped with N side information bits of an arbitrary
representation of the statistics of the input source. We investigate the minimum value of N
such that rate-distortion performance of this quantizer would be essentially the same as the
optimum quantizer for the given source.
