Abstract

----------------------- page 1----------------------- 1/1 resumo "previsãƒo de vetor de movimento temporal com base em unidade de subprevisãƒo (pu) em hevc e projeto de sub-pu em 3d-hevc" trata-se de tã©cnicas que sã£o descritas para previsã£o de movimento com base em unidade de subprevisã£o (pu) para codificaã§ã£o de vã­deo em hevc e 3d-hevc. em um exemplo, as tã©cnicas incluem um modo de previsã£o de vetor de movimento temporal avanã§ado (tmvp) para prever sub-pus de uma pu em codificaã§ã£o de camada ãºnica para a qual o aperfeiã§oamento de vetor de movimento pode ser permitido. o modo de tmvp avanã§ado inclui determinar vetores de movimento para a pu em pelo menos dois estã¡gios para derivar informaã§ãµes de movimento para a pu que incluem vetores de movimento diferentes e ã­ndices de referãªncia para cada uma dentre as sub-pus e a pu. em outro exemplo, as tã©cnicas incluem armazenar informaã§ãµes de movimento separadas derivadas para cada sub-pu de uma pu atual prevista com o uso de um modo de previsã£o de sã­ntese de vista posterior de sub-pu mesmo apã³s a compensaã§ã£o de movimento ser realizada. as informaã§ãµes de movimento adicionais armazenadas para a pu atual podem ser usadas para prever pus subsequentes para as quais a pu atual ã© um bloco prã³ximo.
