Abstract

Sposób dekodowania obrazu obejmuje etapy: decydowanie o trybie predykcji, który odpowiada blokowi składowej chromatycznej; decydowanie o trybie pomijania przekształcenia dla bloku składowej chrominancji spośród wielu potencjalnych trybów pomijania przekształcenia, zgodnie z trybem predykcji, który odpowiada blokowi składowej chrominancji; oraz przekształcanie odwrotne bloku składowej chrominancji na podstawie trybu pomijania przekształcenia.
