Abstract

A baseline mode of Trellis coded quantization (TCQ) is described as used in JPEG 2000 along with the results of visual evaluations which demonstrate TCQ effectiveness over scalar quantization (SQ). Furthermore, a reduced complexity TCQ mode is developed and described in detail. Numerical and visual evaluations indicate that compression performance is nearly identical to baseline TCQ, but with greatly reduced memory footprint and increased progressive image decoding facilities.
