| Research Abstract |
Two-dimensional code typified by the QR code is now spread widely, but it has problem that it is harmful to design of printed materials because they depict an inorganic pattern. In this study, we propose a generating method of two-dimensional code which is easily recognized by users with minimum deterioration of original image and design quality. The results of experiments to extract embedded information from printed materials captured by cell phone attached camera indicate the effectiveness of the proposed method.
