Abstract
as técnicas são descritas para intra-previsão de vídeo melhorada usando a combinação de previsão dependente de posição na codificação de vídeo. na codificação de vídeo de alta eficiência um conjunto de 35 preditores lineares é usado para fazer intra codificação e a previsão pode ser calculada a partir de um conjunto não filtrado ou filtrado de pixels de ?referência? vizinhos, dependendo do modo do preditor e do tamanho do bloco selecionados. as técnicas desta revelação podem usar uma combinação ponderada de ambos os conjuntos não filtrado e filtrado de pixels de referência para obter uma melhor compressão através da previsão melhorada e, portanto, pequeno residual, permitir o cálculo paralelo eficaz de todos os conjuntos de valores de previsão e manter baixa complexidade através da aplicação da filtragem apenas a um conjunto de pixels de referência e não aos próprios valores previstos.
