Abstract

Se proporciona un método para codificar una imagen latente que tiene por lo menos dos componentes de color en una imagen visible. Se generan una primera y segunda imagen asociadas al primer y segundo componentes de color, respectivamente. La primera imagen tiene una primera configuración de elementos y la segunda imagen tiene una segunda configuración de elementos que se manipulan basado en un componente de color correspondiente provisto en la imagen latente. Se asignan un primero y un segundo ángulo a la primera imagen y a la segunda imagen, respectivamente. La primera imagen y la segunda imagen se alinean orientando la primera configuración de elementos de acuerdo con el primer ángulo y la segunda configuración de elementos de acuerdo con el segundo ángulo, respectivamente. La primera imagen alineada y la segunda imagen alineada se superponen para representar una imagen codificada que se decodifica usando un decodificador que presenta simultáneamente el primer componente de color y el segundo componente de color de la imagen latente para presentar una imagen compuesta de color.
