Abstract

1/1 resumo “remoção de clipping de candidato a previsor de vetor de movimento para codificação de vídeo” essa descrição descreve as técnicas para 5 codificação de um bloco de vídeo com base em uma versão sem clipping de um candidato a previsor de vetor de movimento. as técnicas incluem determinar uma lista de candidatos a previsor de vetor de movimento incluindo os candidatos a previsor de vetor de movimento a partir de blocos de vídeo 10 vizinhos sem clipping dos candidatos a previsor de vetor de movimento. mais especificamente, se um ou mais candidatos a previsor de vetor de movimento apontar para um bloco de previsão localizado fora de um limite de imagem de regerencia com relação ao bloco de vídeo atual, as técnicas 15 permitem que uma versão sem clipping do candidato a previsor de vetor de movimento seja incluída na lista de candidatos. o bloco de vídeo atual é então codificado com base em uma lista de candidatos. a eliminação do processo de clipping de candidatos a previsor de vetor de movimento 20 reduz a complexidade em ambos o codificador de vídeo e decodificador de vídeo.
