Distortion resistant double-data correcting color transition barcode and method of generating and using same
Реферат: A color barcode symbology is disclosed that can be accurately decoded despite severe distortions, misreads or altered symbols. This disclosed barcode is a color transition barcode having linear growth properties designed to resist the single or combined effects of: scaling distortions, perspective distortions, shear distortions, and wave distortions of both the uniform and non-uniform type distributed across the barcode's vertical or horizontal axis. This color barcode symbology is also resistant to missing symbols and altered symbols while offering, high security, error checking, and double error correcting capability.
