Abstract

INOVAÇÕES EM PREDIÇÃO E ESTIMATIVA DE VETOR DE BLOCO DE VALORES DE AMOSTRA RECONSTRUÍDOS DENTRO DE UMA ÁREA DE SOBREPOSIÇÃO. A presente invenção refere-se a inovações em opções do lado de codificador para um modo de predição de cópia intrabloco ("BC") para facilitar a predição intra BC, que é mais efetiva em termos de desempenho de distorção de taxa e/ou eficiência computacional de codificação. Por exemplo, algumas das inovações referem-se à estimativa de valores de amostra dentro de uma área de sobreposição de um bloco corrente durante a estimativa de vetor de bloco. Outras inovações referem-se à predição de valores de vetor de bloco ("BV") durante a codificação ou decodificação utilizando abordagens de "pingue-pongue".
