Abstract

MÉTODO PARA CODIFICAÇÃO/DECODIFICAÇÃO DE SINAL DE IMAGEM, E DISPOSITIVO PARA O MESMO. Um método de decodificação de sinal de vídeo de acordo com a presente revelação inclui particionar uma imagem atual em uma pluralidade de peças, decodificar informações de particionamento representando um tipo de fatia, em que as informações de particionamento representam se uma fatia retangular é aplicada, decodificar informações de largura e informações de altura para uma primeira fatia, decodificar informações de valor de diferença de índice de peça para a primeira fatia e determinar um índice de uma peça superior esquerda de uma segunda fatia com base nas informações de valor de diferença.
