Abstract

SE MEJORA LA IMAGEN DE UNA ESCENA PARCIALMENTE OSCURECIDA POR LUZ ATMOSFERICA RETRODISPERSA TENIENDO EN CUENTA LAS VARIACIONES EN LA COMPONENTE MEDIA DEL FLUJO RETRODISPERSO QUE RESULTA DE LAS VARIACIONES EN LA DISTANCIA ENTRE EL PUNTO DESDE EL QUE SE CAPTURA LA IMAGEN Y LOS PUNTOS DEL TERRENO QUE CONTRIBUYEN A LA ESCENA. SE CAPTURAN UNA SERIE DE IMAGENES DE LA ESCENA Y SE PRODUCE UNA IMAGEN PROMEDIADA EN LA CUAL CADA PIXEL POSEE UN BRILLO QUE ES LA MEDIA DE LOS BRILLOS DE AQUELLAS ZONAS DE LAS IMAGENES CAPTURADAS QUE REPRESENTAN LA MISMA ZONA DE LA ESCENA QUE DICHO PIXEL. SE DEFINE UN MODELO PARA REPRESENTAR LA RELACION ENTRE EL BRILLO DE UN PIXEL DE LA IMAGEN PROMEDIADA Y LA DISTANCIA ENTRE EL PUNTO DE VISTA DESDE EL QUE SE REPRESENTA LA IMAGEN Y EL PUNTO DE LA ESCENA REPRESENTADO POR ESE PIXEL DE LA IMAGEN. SE COMPUTA UNA ESTIMACION DE LA CONTRIBUCION DE LA LUZ ATMOSFERICA RETRODISPERSA AL BRILLO DE CADA PIXEL DE LA IMAGEN A PARTIR DEL MODELO. LA CONTRIBUCION ESTIMADA PARA CADA PIXEL SERESTA DEL BRILLO DE ESE PIXEL DE LA IMAGEN PARA PRODUCIR UN BRILLO MODIFICADO PARA ESE ELEMENTO. LA IMAGEN SE RECONSTRUYE, TENIENDO CADA ELEMENTO DE LA IMAGEN RECONSTRUIDA UN BRILLO QUE ES FUNCION DEL BRILLO MODIFICADO DE ESE ELEMENTO.
