Visual code and method for encoding and decoding a two-dimensional image

The present description relates to a 2D visual code based on the superposition of pure flat waves framed in black, designed to be read at long distances, with different types of degradation (noise, blurring or movement) and in adverse lighting conditions. To this end, the information carrying elemen...

Zusammenfassung:The present description relates to a 2D visual code based on the superposition of pure flat waves framed in black, designed to be read at long distances, with different types of degradation (noise, blurring or movement) and in adverse lighting conditions. To this end, the information carrying elements are waves that are distributed over the whole image. The combination of waves with different directions, frequencies, amplitudes and phases permits generating a high number of configurations that may be decoded in a robust and efficient manner.
