Abstract
Hay una codificación. La codificación puede incluir preparar datos de compresión de video con base en imágenes de origen. La preparación puede incluir particionar las imágenes de origen en unidades de codificación y/o generar una unidad de transformación que tiene un arreglo de transformación. La preparación puede también incluir procesar la unidad de transformación generada. El procesamiento puede incluir generar un mapa de importancia, que tiene un arreglo de mapa de importancia con ubicaciones y-x correspondientes a las ubicaciones y-x del arreglo de transformación. El procesamiento puede también incluir determinar, utilizando un patrón de exploración, un modelo de contexto para codificar un elemento de mapa de importancia de la pluralidad de elementos de mapa de importancia con base en un valor asociado con al menos un elemento de mapa de importancia vecino codificado de la pluralidad de elementos de mapa de importancia en el arreglo de mapa de importancia. También hay una decodificación que incluye procesar datos de compresión de video que son generados en la codificación.
