Infra-red data structure printed on a photograph |
摘要 |
A data structure is printed on a photograph using infra-red ink. The data structure includes a two dimensional array of data blocks. Each adjacent pair of data blocks is separated by a gap and each of the data blocks has a data region holding encoded data. Each data region is confined by clock-marks and borders to facilitate location of the data region and recovery of data from within the data region.
