Abstract: | Visual cryptography is expected to have various applications since it has potential for visual decoding. However, there are
still few practical applications. One reason for this is the difficulty of superposition to decode. To solve the alignment
difficulty, we propose an information hiding method which can be physically decode by superimposing a checkered pattern. Superimposing
a checkered pattern can also be considered as a kind of image sampling process, and a decoding experiment using an ordinary
compact digital camera is presented. |
