This new technique has been applied to the LAR codec and shows an improvement over previous studies up to 20% in rate and 0.5db in PSNR at low bit rates.

Jan 10, 2023 · The VVC codec is applied to the task of multispectral image (MSI) compression using adaptive and scalable coding structures.

ABSTRACT. This paper presents and investigates a new family of reversible low- complexity colour transformations. It shows that, for a reasonably.

Adaptive inter component decorrelation improves the compression ratio for all images and colour spaces. The most significant improvements are realised with.

A Good Practical Approach: combine the adaptive linear prediction with the context switching (context = separate parameter set); no longer a “simple linear ...
