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.A method is provided for encoding a latent image that has at least two color components in a visible image. A first and second image associated with the first and second color components, respectively, are generated. The first image has a first element configuration and the second image has a second configuration of elements that are manipulated based on a corresponding color component provided in the latent image. A first and a second angle are assigned to the first image and the second image, respectively. The first image and the second image are aligned by orienting the first configuration of elements according to the first angle and the second configuration of elements according to the second angle, respectively. The first aligned image and the second aligned image are superimposed to represent an encoded image that is decoded using a decoder that simultaneously presents the first color component and the second color component of the latent image to present a composite color image.
