Analysis of trellis quantization for near-lossless image coding
Abstract
Trellis quantization (TQ) is investigated for near-lossless image coding. The TQ process is extended to the 2-dimensional case by using a planar predictor and by doing the optimization for each row separately. The results obtained for various standard test images used are presented. Several variations of the TQ process are also discussed.
