Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO DE COMPRESSãO DE VìDEO"<D>. A invenção refere-se a um processo de compressão de dados digitais de uma seq³ência de imagens de síntese que descreve uma cena objeto de um script, que compreende uma etapa de tratamento (1, 11) para a modelação da cena a partir de dados matamáticos, uma etapa de conversão de imagem ("redering" em anglo-saxão) para a criação de uma imagem de síntese a partir dessa modelação e uma divisão em blocos de imagem dessa imagem de síntese (2, 12), uma codificação diferencial do bloco de imagem corrente a partir de um bloco de pelo menos uma imagem de síntese definido a partir de pelo menos um vetor de movimento para fornecer um bloco de resíduo (4i), caracterizado pelo fato de que o valor de movimento é calculado a partir dos dados matemáticos provenientes do script de síntese e que definem o movimento aparente dos diferentes objetos que constituem a cena objeto da seq³ência. As aplicações são a síntese de imagem em produção. Para jogos em vídeo, são por exemplo aplicações de interatividade ou de realidade virtual.
