Abstract

Bir görüntü kodlama şemasında, bir girdi görüntü, birden fazla görüntü öğesini (610) içeren birkaç görüntü blokuna (600) ayrıştırılır. Ardından görüntü blokları (600), kodlanmış blok gösterimleri (700) haline kodlanır. Böyle bir blok gösterimi (700), bir renk kod kelimesini (710), bir yoğunluk kod kelimesini (720) ve yoğunluk gösterimlerinin bir dizisini (730) içerir. Gösterim dizisi (730), bloktaki (600) her görüntü öğesi (610) için bir yoğunluk gösterimini içerir; burada bir gösterim, yoğunluk değiştirici kümedeki yoğunluk değiştiricilerden birini tanımlar. Kod çözme sırasında, renk ve yoğunluk kod kelimeleri (710, 720) ve yoğunluk gösterimleri (730), bloktaki (600) görüntü öğelerinin (610) bir kodu çözülmüş gösterimini üretmek için kullanılır.
