Abstract

El invento posibilita el monitoreo automático, de un flujo refinado, que sale por una caldera de recuperación, basada en información óptica. Se emplea un procesador, para leer a lo menos una secuencia de video representada en forma estacionaria, que comprende fotogramas de fotografía digital, que comprende un área bajo examinación, que representa a lo menos, una parte de un flujo refinado, que sale de la caldera de recuperación. Se emplea el procesador, para identificar, en el área bajo examinación, un área distinguible basada en la información de color y/o intensidad. Se emplea el procesador para determinar, basado en el área distinguible identificada, una propiedad de flujo monitoreada del flujo refinado.
