Abstract: A computer-implemented method for creating an encoder-decoder system for embedding information in a decorative label, the method comprising: defining a family of encoder functions and a family of decoder functions, each encoder function configured to encode information as a respective modification of a decorative label, each decoder function configured to decode an image of a modified decorative label into respective decoded information; applying an iterative optimization process to determine an optimized encoder-decoder pair comprising an optimized encoder function and an optimized decoder function, the optimized encoder function selected by the iterative optimization process, the iterative optimization process being configured to determine the optimized encoder-decoder pair so as to at least approximately optimize a detection reliability of the optimized decoder function when decoding images of decorative labels that have been modified using the optimized encoder function.
