Abstract

resumo patente de invenção: "processo de codificação e decodificação de imagens, dispositivo de codificação e decodificação e programas de computador correspondentes". a presente invenção refere-se a um processo de codificação de pelo menos uma imagem recortada em divisões, uma divisão corrente a codificar contendo dados dos quais 10 menos um dado é atingida por um sinal. esse processo de codificação é caracterizado pelo fato de utilizar, para essa divisão corrente, as seguintes etapas: - cálculo (s3) do valor de uma função representativa dos dados dessa divisão corrente com exclusão desse sinal; - comparação (s4) desse valor calculado a um valor predeterminado desse sinal; - em função do resultado dessa comparação, modificação (s5) ou não de pelo menos um dos dados da divisão corrente; - em caso de modificação, codificação (s20) de pelo menos um 20 dado modificado.
