難視性パターンを用いた印刷物保護とその応用

抄録

We have proposed an artificial fiber pattern as a technique for embedding electrical information into the real world such as a paper, a wallpaper and clothes. This technique can protect printed material by embedding the printing log. In recent studies, we tried to extract embedded information in an artificial fiber pattern using a high-resolution digital camera instead of a scanner. In addition, we attempted to use a relatively inexpensive and low-resolution Web camera as an input device because one of the important applications of our technique is an augmented reality system. In addition, from a design perspective, we examined different colors (cyan, magenta, and yellow) instead of the grayscale, and a specific pattern (a traditional Japanese katagami pattern for a kimono (i.e., Ise-katagami) ) instead of a paper fiber pattern.
