Abstract

DERIVAÇÃO DE FAIXA DE VETOR DE MOVIMENTO PARA FILTRO DE INTERPOLAÇÃO APRIMORADO. A revelação refere-se a um método para codificar dados de vídeo usando um modelo de movimento afim que evita uma redução significativa da faixa de vetor de movimento próximo aos limites de imagem. O método compreende as etapas de: obter um vetor de movimento central, mv_center, de um bloco de codificação, derivar uma primeira faixa de vetor de movimento para o bloco de codificação com base no vetor de movimento central e em uma dispersão de vetor de movimento, em que a dispersão de vetor de movimento depende de um tamanho do bloco de codificação; se a primeira faixa de vetor de movimento estiver pelo menos parcialmente apontando para fora de uma primeira área incluindo uma imagem de referência, atualizar a primeira faixa de vetor de movimento para estar apontando dentro da primeira área, tal que um valor mínimo e/ou um valor máximo da primeira faixa de vetor de movimento atualizada está apontando para o limite da primeira área, em que a diferença entre o valor máximo e o valor mínimo da primeira faixa de vetor de movimento atualizada é igual ao mínimo de um valor duplo da dispersão de vetor de movimento e o tamanho da primeira área; e realizar compensação de movimento baseada em pixel com base na primeira faixa de vetor de movimento atualizada.
