Abstract

Una imagen se puede dividir en subimágenes/segmentos/mosaicos. Por ejemplo, la imagen puede dividirse en subimagen(es), y la información relacionada con subimágenes puede usarse para codificación. La información relacionada con subimágenes puede ser generada por un dispositivo de codificación y transmitida a un dispositivo de decodificación. De acuerdo con modalidades del presente documento, la información relacionada con subimágenes puede señalizarse de manera eficiente.
