Abstract

em um método para melhorar a retrocompatibilidade ao decodificar imagens de alto alcance dinâmico codificadas em um espaço com ampla gama de cores (wcg) que pode não ser compatível com espaços de cor herdados, valores de saturação e/ou matiz de imagens em um banco de dados de imagens são calculados para ambos um espaço de cor herdado (isto é, ycbcr-gama) e um espaço de cor wcg preferido (isto é, ipt-pq). com base em uma função de custo, um espaço de cor regenerado é calculado, de modo que a distância entre os valores de matiz no espaço de cor herdado e valores de matiz rotacionados no espaço de cor preferido seja minimizada. imagens hdr são codificadas no espaço de cor regenerado. dispositivos herdados podem ainda decodificar imagens de alcance dinâmico padrão assumindo que elas codificadas no espaço de cor herdado, enquanto dispositivos atualizados podem usar informações de regeneração de cor para decodificar imagens hdr no espaço de cor preferido em alcance dinâmico total.
