Abstract
MÉTODO DE CODIFICAÇÃO DE VÍDEO DE BI-PREDIÇÃO VETORES DE MOVIMENTO A PARTIR DE CANDIDATO DE FUSÃO E UNIPREDICÇÃO. É divulgado um método de modo de Interpredição bi- preditivo utilizando um vetor de movimento uni-preditivo e um segundo vetor de movimento associado com um candidato de Fusão. No lado de codificador, a informação de movimento codificada para um vetor de movimento de uni-predição para o bloco atual é gerada utilizando um preditor de vetor de movimento selecionado de uma lista de candidatos de predição de vetor de movimento (MVP) . Além disso, um candidato de Fusão com um segundo vetor de movimento apontando para a outra direção de predição é identificado de acordo com um índice de Fusão. O vetor de movimento de uni-predição e o segundo vetor de movimento do candidato de Fusão são usados para codificação de bi-predição do bloco atual. No lado de decodificador, o processo de decodificação correspondente é revelado.
