Abstract

Un método computacional de generación de al menos una imagen con información codificada que comprende los pasos de i) asociar una información a codificar a una pluralidad de elementos gráficos, generando así un patrón de elementos gráficos y ii) generar por lo menos una imagen que comprenda por lo menos un patrón obtenido a partir del paso i), un sistema asociado al referido método, imágenes obtenidas a partir del referido método bien como un método y un sistema de lectura de esas imágenes. Este método introduce una forma sólida y altamente flexible de codificar información en una imagen.
