Abstract

"OCULTAçãO DE ERROS ESPACIAIS BASEADA NOS MODOS DE INTRAPREVISãO TRANSMITIDOS EM UM FLUXO CODIFICADO" Ocultação espacial de erros em uma intra-imagem compreendida de um fluxo de macroblocos (110) é obtida mediante previsão dos dados desaparecidos em um macrobloco (110) com base em um modo de intraprevisão especificado nos blocos vizinhos (120) . Na prática, quando macroblocos (110) dentro de um fluxo são codificados por uma técnica de codificação baseada em blocos, tal como técnica de codificação especificada no padrão H.264 ISO/ITU, um macrobloco (110) pode ser previsto para fins de codificação com base em modos de intraprevisão vizinhos especificados pelo propósito de codificação baseado em modos de intraprevisão, vizinhos, especificados pela técnica de codificação.
