Abstract

resumo patente de invenção: "processo de codificação e decodificação de imagens, dispositivo de codificacão e de decodificação, e programas de computador correspondentes". a presente invenção refere-se a um processo de codificação, compreendendo o recorte (c1) da imagem em uma pluralidade de blocos (mb) aptos a conter símbolos que pertencem a um conjunto predeterminado de símbolos, o agrupamento (c2) de blocos em um número predeterminado (p) de subconjuntos de blocos (se1, se2,...sek,..., sep), a codificação (c3) por meio de um módulo de codificação entrópica, de cada um desses subconjuntos de blocos, por associação de informações numéricas aos símbolos de cada bloco de um subconjunto considerado, essa etapa de codificação compreendendo, para o primeiro bloco da imagem, uma subetapa (c33) de inicialização de variáveis de estado desse módulo de codificação entrópica, depois a geração de um subfluxo de dados representativo de pelo menos um desses subconjuntos de blocos codificados. no caso em que o bloco corrente é o primeiro bloco a codificar de um subconjunto considerado, determinação de probabilidades de aparecimento de símbolo para esse primeiro bloco corrente, essas probabilidades são aquelas que foram determinadas para um bloco predeterminado codificado e decodificado de pelo menos um outro subconjunto. no caso em que o bloco corrente é o último bloco codificado do subconjunto considerado, procede-se à escritura (c45), no subfluxo representativo de pelo menos um subconjunto considerado, da totalidade das informações numéricas que foram associadas aos símbolos, quando da codificação dos blocos desse subconjunto considerado, e procede-se à utilização (c46) da subetapa de inicialização.
