SYSTEM AND METHOD FOR ENCODED SPATIO-SPECTRAL INFORMATION PROCESSING

摘要

Systems and methods for encoded spatio-spectral information processing are disclosed. In a specific aspect, the invention involves applying or embeddin g of digital information in the spectral profile of materials, such as inks an d paints, to provide the functionality of bar codes or labels, and reading suc h information from objects. Recording of digital information is enabled onto o r into physical media with or without the use of printed symbols, by spraying, mixing or enabling a specific chemical changes resulting in digital information being encoded onto or into carrying materials. Because the information is encoded in the spectral signatures of compositions of materials, the precise location, shape, orientation and arrangement of marks is generally not used in the process of decoding. Various applications are disclosed.
