    • Systems and methods for encoded spatio-spectral information processing are disclosed. In a specific aspect, the invention involves applying or embedding of digital information in the spectral profile of materials, such as inks and paints, to provide the functionality of bar codes or labels, and reading such information from objects. Recording of digital information is enabled onto or 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.
    • 公开了用于编码的空间光谱信息处理的系统和方法。 在具体方面,本发明涉及将数字信息应用或嵌入材料(例如油墨和油漆)的光谱轮廓中,以提供条形码或标签的功能,以及从物体读取这些信息。 通过喷洒,混合或使特定的化学变化导致数字信息被编码到载体材料上或载入材料中,可以将数字信息记录到物理介质上或物理介质上或不使用印刷符号。 由于信息是在材料组成的光谱特征中编码的,所以在解码过程中通常不使用标记的精确位置,形状,取向和排列。 公开了各种应用。
