Hybrid transmission, compression and data hiding: quantisation index modulation as source coding strategy
L. Guillemot, Jean-Marie Moureaux · Electronics Letters · 2004
A new hybrid compression and data hiding scheme based on quantisation index modulation and lattice vector quantisation is presented. The design of an appropriate vector dead zone and an adapted indexing technique makes this hybrid quantisation strategy very efficient, particularly in the field of image compression using wavelet transform.
