Abstract

Un método de decodificación de imágenes de acuerdo con la presente invención puede comprender: dividir un cuadro en una pluralidad de mosaicos; y determinar al menos una rebanada con base en la pluralidad de mosaicos. Aquí, dividir un cuadro en una pluralidad de mosaicos puede comprender: determinar la anchura de una primera columna de mosaicos en el cuadro; y determinar la anchura de una segunda columna de mosaicos que limita con la primera columna de mosaicos.
