Abstract

La invención se refiere a un método y un dispositivo para detectar y descodificar un patrón bidimensional codificado, p. ej. del tipo patrón de codificación robusta (REP), incluso en caso de que el patrón esté aplicado sobre un fondo de color no uniforme de una superficie de un sustrato. Las operaciones para descodificar dicho patrón codificado implican detectar los estados de sus símbolos a través de un patrón de prueba, comprobar que las diferencias locales entre los valores de parámetro de los elementos de los símbolos son coherentes con una representación permitida del patrón de prueba para asignar, mediante asignación de tipo uno a uno, los estados de los símbolos del patrón de prueba a los correspondientes símbolos del patrón codificado, y descodificar el patrón codificado en función de la representación asignada de sus símbolos.
