Abstract
FILTRAÇÃO BASEADA EM REDE NEURAL DE COMPONENTE CONJUNTO DURANTE CODIFICAÇÃO DE VÍDEO. Um dispositivo de exemplo para decodificar dados de vídeo inclui uma memória configurada para armazenar dados de vídeo; e um ou mais processadores implementados em conjunto de circuitos e configurados para: aplicar uma camada de rede neural de convolução de subamostragem a um primeiro componente de cor de um bloco de dados de vídeo, o primeiro componente de cor do bloco tendo um primeiro tamanho, em que a aplicação da camada de rede neural de convolução de subamostragem ao primeiro componente de cor gera um primeiro componente de cor subamostrado tendo um segundo tamanho menor do que o primeiro tamanho; filtrar um segundo componente de cor tendo o segundo tamanho para formar um segundo componente de cor filtrado; concatenar o primeiro componente de cor subamostrado com o segundo componente de cor filtrado para formar componentes de cor concatenados; e filtrar os componentes de cor concatenados para formar um componente concatenado filtrado incluindo um primeiro componente de cor subamostrado filtrado.
