Abstract

DECODIFICADOR E MÉTODOS CORRESPONDENTES PARA SINALIZAR INFORMAÇÕES DE PARTICIONAMENTO DE IMAGEM PARA FATIAS. Um método de codificação implementado por um dispositivo de decodificação e um decodificador são divulgados, o método compreendendo: obter um fluxo de bits para uma imagem atual; obter uma quantidade de peças em uma linha de peças da imagem atual; obter um valor de um endereço de uma fatia atual, a fatia atual é compreendida na imagem atual; obter um valor de tileX de acordo com o valor do endereço da fatia atual; analisar um valor de indicação para uma largura de fatia do fluxo de bits para a imagem atual, quando um valor de diferença entre a quantidade de peças na linha de peças da imagem atual e o valor de tileX não for igual a um primeiro limiar.
