| Abstract(in English) | Because Two-dimensional barcodes like a QR code can be read by terminals which equip camera device, it is frequently used for various occasions. However, when a QR code is displayed at advertising catalog, its perceptual patterns impair the appearance. Therefore, we focused on a specific application to develop a two-dimensional barcode in order not to impair the appearance. In this paper, we propose a new type two-dimensional code looks like a soccer ball such that the appearance matches the advertising catalog designed for soccer events. We develop an application for smart phone that can extract data from the proposed two-dimensional barcode using various signal processing operations. Furthermore, by using an error correcting code we improve the tolerance for noise injected at the optical reading process of the barcode. |
