Abstract

codificação e decodificação de imagem. uma imagem (1) com múltiplos pedaços (2-5) é codificada através de geração de uma representação de pedaço codificado para cada um dos pedaços. um sinalizador de pedaço é definido para um primeiro valor para o primeiro pedaço (2) na imagem (1) e sinalizadores de pedaços correspondentes dos pedaços remanescentes (3-5) sáo definidos para um segundo valor definido. um endereço de pedaço respectivo é gerado para cada pedaço remanescente (3-5) para permitir a identificação da posição de início de pedaço na figura (1) para o pedaço. uma representação de imagem codificada (50) da imagem (1) compreende as representações dos pedaços codificadas, os endereços dos pedaços e os sinalizadores dos pedaços. os sinalizadores dos pedaços permitem a diferenciação entre os pedaços (3-5) para os quais os endereços são requeridos e o pedaço (2) por imagem (1) para o qual não é necessário um endereço de pedaço para identificar sua posição de início de pedaço.
