Abstract

Se proporciona un método para computarizar la generación de una imagen mejorada basado en una pluralidad de imágenes adquiridas (por ej., imágenes del SAR) y un sistema del mismo. El método comprende: (a) recibir una pluralidad de imágenes adquiridas, comprendiendo cada una de ellas un área de interés común; (b) recibir parámetros de procesamiento; c) agrupar dicha pluralidad de imágenes adquiridas dentro de uno o más grupos; (d) procesar las imágenes dentro de dicho uno o más grupos, donde dicho procesamiento comprende: i) para cada píxel dado dentro del área de interés común, calcular la probabilidad de discrepancia entre los píxeles respectivos de las imágenes de dicho uno o más grupos, dando de este modo lugar a la probabilidad de los valores de discrepancia que caracterizan dicho píxel dado; ii) generar una “probabilidad de matriz de discrepancia” que comprende la probabilidad de los valores de discrepancia, que caracterizan la probabilidad de discrepancia para cada pixel dentro del área común de interés; iii) para cada uno de dicho único o más grupos, generar una imagen mejorada mientras se utiliza dicha probabilidad de la matriz de discrepancia.
