Abstract

Dada una secuencia de imágenes en una primera representación de palabra clave, métodos, procesos, y sistemas se presentan para la reconfiguración de imágenes usando la optimización de distorsión–tasa, donde la reconfiguración permite codificar las imágenes en una segunda representación de palabra clave que permite una compresión más eficiente que mediante el uso de primera representación de palabra clave. También se presentan los métodos de sintaxis para los parámetros de reconfiguración de la señalización.
