Abstract
um método e um aparelho para codificação e decodificação de imagem através de interprevisão são fornecidos. o método de decodificação inclui: determinar informações de movimento de previsão de um primeiro bloco de decodificação; desempenhar previsão bidirecional no primeiro bloco de decodificação com base nas informações de movimento de previsão para obter um primeiro bloco de previsão de decodificação; desempenhar busca de movimento de primeira precisão em um bloco de imagem de referência de previsão para obter pelo menos um segundo bloco de previsão de decodificação, onde uma localização de busca da busca de movimento é determinada usando-se um previsor de vetor de movimento e a primeira precisão; calcular uma diferença entre o primeiro bloco de previsão de decodificação e cada segundo bloco de previsão de decodificação para obter um previsor de vetor de movimento alvo do primeiro bloco de decodificação; e atualizar o previsor de vetor de movimento alvo através da busca de movimento. portanto, a precisão de movimento de interprevisão é aperfeiçoada.
