Abstract

método de decodificação de vídeo. em um processo de codificação e decodificação de vídeo são fornecidos um método e aparelho para determinar se uma fatia incluindo um pixel adjacente localizado no lado superior esquerdo ou inferior direito de um pixel atual entre os pixels adjacentes usados para um filtro em laço adaptativo do pixel atual é diferente de uma fatia incluindo o pixel atual, quando a fatia incluindo o pixel adjacente na localização superior esquerda ou inferior direita é diferente da fatia incluindo o pixel atual, determinar um valor do pixel adjacente localizado no lado superior esquerdo ou infe rior direito como um valor de um pixel mais próximo em uma direção horizontal do pixel adjacente localizado no lado superior esquerdo ou inferior direito entre os pixels incluídos na fatia incluindo o pixel atual, determinar um filtro em laço adaptativo in cluindo um coeficiente de filtro para o pixel atual e os pixels adjacentes com base nos valores do pixel atual e os pixels adjacentes,corrigir o valor do pixel atual usando os valores dos pixels adjacentes aplicar o filtro em laço adaptativo ao pixel atual e codificar/decodificar um bloco atual incluindo o pixel atual.
