Abstract

MéTODO PARA EXTRAçãO DE COR DOMINANTE DE CONTEúDO DE VìDEO CODIFICADO EM UM ESPAçO DE COR RENDERIZADO Extrair e processar conteúdo de vídeo codificado em um espaço de cor renderizado a ser emulado por uma fonte de luz ambiente, usando regras perceptivas para seleção de cor dominante inteligente. Etapas incluem quantizar o espaço de cor de vídeo; executar extração de cor dominante usando um modo, mediano, médio, ou média ponderada de cromaticidades de pixel; aplicar regras perceptivas para adicionalmente derivar cromaticidades dominantes por ¢1! transformadas de cromaticidade; ¢2! uma média ponderada usando uma função de ponderação de pixel influenciada por conteúdo de cena; e ¢3! extração de cor dominante estendida, onde ponderação de pixel é reduzida para pixéis de maioria; e ¢4! transformar a cor dominante escolhida ao espaço de cor de luz ambiente usando matrizes de tristímulo. Uma cor de interesse pode ser adicionalmente analisada para produzir uma cor dominante verdadeira, e quadros de vídeo passados podem guiar a seleção de cores dominantes em quadros futuros.
