Abstract

construção de candidato de vetor de movimento para modo de particionamento geométrico em codificação de vídeo. um codificador de vídeo pode ser configurado para determinar um particionamento para um bloco de dados de vídeo com o uso do modo de particionamento geométrico; para construir duas listas de candidatos de vetor de movimento de unipredição para o bloco de dados de vídeo e para codificar o bloco de dados de vídeo com o uso de unipredição com base em pelo menos uma das duas listas de candidatos de vetor de movimento de unipredição para gerar um bloco decodificado de dados de vídeo.Motion vector candidate construction for geometric partitioning mode in video coding. a video encoder may be configured to determine a partitioning for a block of video data using geometric partitioning mode; to construct two uniprediction motion vector candidate lists for the video data block and to encode the video data block using uniprediction based on at least one of the two uniprediction motion vector candidate lists to generate a decoded block of video data.
