Abstract

UM EQUIPAMENTO E UM MéTODO PARA CODIFICAR DADOS DE IMAGEM DIGITAL EM UMA MANEIRA SEM PERDAS. Um método (900) de compressão e codificação sem perdas de sinais representando informação de imagem é reivindicado. Um arquivo comprimido de dados com perdas (922) e um arquivo comprimido de dados residuais (960) são gerados. Quando o arquivo comprimido de dados com perdas e o arquivo comprimido residual são combinados, um arquivo de dados sem perdas que é substancialmente idêntico ao arquivo de dados original é criado.
