Adaptive wavelet packet based image coding with optimal entropy-constrained lattice vector quantizer (ECLVQ)

摘要

In this work, wavelet basis and source coding are jointly optimized, while specifying the source coding strategy as entropy-constrained lattice vector quantizer (ECLVQ). The presented approach differs from previous works in which the choice of wavelet basis is quasioptimal, but the quantizer set is optimally chosen.
