摘要

「摩爾紋」是一種水波狀的紋路。當我們將數個有重複圖樣的透明圖層疊在一起時，摩爾紋便會顯現。在本篇論文中提出了將灰階影像或彩色影像隱藏在摩爾紋中的方法；換句話說，若把我們產生的圖層疊在一起，人們便能在其產生的摩爾紋中辨認出隱藏影像。我們由摩爾紋基本定理推導出摩爾紋圖像隱藏可藉由連續調相達成。並且，我們也將此種圖像隱藏方法適用於多種應用，包含：摩爾紋藝術、視覺密碼、特殊的影像隱藏方法。每一種應用都達到驚奇且有趣的結果。

"Moiré pattern" is some rippled patterns appearing when superposing repetitive structures. In this thesis we developed an image hiding method which allowed us to hide grayscale or color secret images in the moiré patterns; in other words, when superposing the generated share images, people are able to recognize the secret image due to the occurring moiré pattern.Our image hiding method is derived from the fundamental moiré theorm, and concluded that the moiré pattern synthesis using continuous phase modulation is feasible. We also applied this image hiding method on multiple applications, such as moiré art, visual cryptography and a special image hiding scheme. All of the applications result in amazing and interesting effects.
