Research output: Contribution to journalConference articlepeer-review


It has been shown in [1, 2] that zero-zone quantizers offer very good R-D tradeoffs, especially at low bit rates, in spite of their simplicity in implementation and concept. In [1] the performance of such codecs for still and moving images were reported for a dyadic 10-band subband coder. In this paper we extend those results to other subband image codecs, and DCT, and compare their performances.
