In order to increase the compression ratio while preserving decent reconstructed image quality, DC coefficients are coded by DPCM and only the most important AC coefficients are coded using classified vector quantization (CVQ).
The proposed transformed classified vector quantization (TCVQ) is a hybrid image compression method that employs the energy-compaction property of DCT and the high compression ratio of CVQ.
