Abstract
Se proporcionan métodos y sistemas para generar un conjunto de funciones de remodelación hacia adelante y hacia atrás para la codificación eficiente de imágenes de alto rango dinámico (HDR). Dado un conjunto inicial de funciones de remodelación hacia adelante, se construyen funciones de remodelación hacia adelante de salida a) utilizando las funciones de remodelación hacia adelante para generar un primer conjunto de funciones de remodelación hacia atrás correspondiente b) generando un segundo conjunto de funciones de remodelación hacia atrás utilizando una representación polinomial de múltiples segmentos con un conjunto común de puntos pivote c) generando un conjunto de salida de funciones de remodelación hacia atrás optimizando la representación polinomial del segundo conjunto de funciones de remodelación hacia atrás para minimizar los valores de separación entre segmentos consecutivos y d) utilizando el conjunto de salida de funciones de remodelación hacia atrás para generar el conjunto de salida de funciones de remodelación hacia adelante minimizando la distancia entre las palabras de código HDR de entrada originales y las palabras de código HDR reconstruidas.
