Decoding a physical image

摘要

A method for decoding information from a physical image having a plurality of payload patches includes generating a digital representation of the physical image. A plurality of regions are mapped to the plurality of payload patches in the digital representation. A scramble pattern is identified and the plurality of mapped regions of the digital representation are reordered according to the identified scramble pattern. Information is decoded from the payload patches of the reordered plurality of mapped regions.
