Abstract

métodos de processamento de vídeo e aparelhos para determinar a decisão de filtro de deblocagem em sistemas de codificação de vídeo. métodos de processamento de vídeo e aparelhos para codificar um bloco atual e um bloco adjacente compreendem receber dados de entrada dos blocos atuais e adjacentes em uma imagem atual, determinar que os blocos atuais e adjacentes são codificados em um modo de bdpcm ou rdpcm, realizar uma operação de filtragem de deblocagem em uma borda entre os blocos atuais e adjacentes desativando a filtragem de deblocagem para um primeiro componente de cor e ativando a filtragem de deblocagem para um segundo componente de cor, e codificar ou decodificar os blocos atuais e adjacentes. cada pixel atual em um bloco codificado por bdpcm é predito por um ou mais pixels vizinhos do pixel atual. a rdpcm é aplicada para processar resíduos quantizados de um bloco codificado por rdpcm de acordo com uma direção de predição do bloco codificado por rdpcm.
