Abstract
De acuerdo con las modalidades descritas en este documento, se pueden usar subimágenes y/o límites virtuales para codificar una imagen. Por ejemplo, las subimágenes en la imagen actual se pueden usar para predecir, reconstruir y/o filtrar la imagen actual. Los límites virtuales se pueden usar para filtrar muestras reconstruidas de la imagen actual. A través de la codificación de imágenes con base en las subimágenes y/o los límites virtuales de acuerdo con las modalidades descritas en este documento, se puede mejorar la calidad subjetiva/objetiva de una imagen y se puede reducir el consumo de recursos de hardware necesarios para la codificación.
