Abstract

em um exemplo, um aparelho inclui uma memória configurada para armazenar dados de vídeo e uma ou mais unidades de processamento implementadas em circuitos configurados para construir uma série de filtros para classes de blocos da imagem atual dos dados de vídeo, no qual, para construir a série de filtros, a unidade ou unidades de processamento são configuradas para gerar uma série de conjuntos de coeficientes de filtro e que identificam um dos conjuntos de coeficientes de filtro, determinar respectivos índices que identificam um dos conjuntos de coeficientes de filtro para o filtro correspondente do subconjunto, decodificar o bloco atual da imagem atual, determinar uma classe para o bloco atual, selecionar um filtro da série de filtros que corresponde à classe para o bloco atual e filtrar pelo menos um pixel do bloco atual utilizando o filtro selecionado.
