Abstract

método de codificação de vídeo, método de decodificação de vídeo, aparelho de codificação de vídeo, aparelho de decodificação de vídeo e programas dos mesmos. a presente invenção refere-se a uma redução em energia residual de previsão entre quadros com compensão de movimento e aperfeiçoamento em eficácia de codificação que são alcançados através do uso de um filtro de interpolação adaptativa do tipo divisão em regiões que leva em consideração uma propriedade de borda de uma imagem. uma unidade de cálculo de borda informações de borda a partir de dado de imagem de referência designados por um vetor de movimento. uma unidade de divisão em regiões divide um quadro alvo de codificação em uma pluralidade de regiões que são unidades ás quais os filtros de interpolação são complicados de maneira adaptativa com base nas informações de borda. uma unidade de otimização de coeficiente de filtro otimiza um filtro de interpolação para um pixel de precisão fracional de referência interpola o pixel de precisão fracional de uma imagem de referência por meio de referência por meio do uso do filtro de interpolação otimizado, e uma unidade de codificação preditiva realiza codificão preditiva por meio do uso de compensação de movimento de precisão fracional.
