Abstract (in Japanese) (See Japanese page) 
(in English) s an alternative to two-dimensional (2D) codes, there is a growing interest in techniques that embed information in images and detect it from their printed counterparts. These techniques generally treat images affixed on a flat surface. One such technique has been proposed to detect information from images on curved surfaces using prior information, such as the radius of a cylindrical surface. However, obtaining prior information may be difficult. In this paper, we propose the use of auxiliary lines instead of relying on prior information, which is sometimes difficult to obtain. In our proposed method, auxiliary lines are added in advance around the image in which data are embedded, and information is detected by correcting the image using these auxiliary lines at the time of capturing. This method can mitigate the limitations of the image-capturing conditions of the conventional method. Finally, the effectiveness of the proposed method is demonstrated by confirming whether information can be detected by attaching the data-embedded image to a cylinder and capturing it.
