演講摘要：

隨著數位科技的快速發展，數位相機的使用日益普遍。中低階 相機為了降低成本在硬體進行影像取樣處理時會利用一個傳感 器來取樣一個彩色像素的三個頻譜資料而不是使用三個傳感 器。這樣的做法需要進行影像解馬賽克的處理將取樣的資料轉 成彩色影像。最近幾年已經有相當多的影像認證技術被提出來 保障數位影像的完整性。在演講中我們將介紹適用於影像解馬 賽克的影像認證技術，並針對這些技術進行探討與結果分析。

With the rapid progress of digital technology, digital still cameras become more and more popular. To reduce the hardware cost in low-cost cameras, a single sensor with a grid of different color sensors, called color filter array is used to capture one color pixel. Then, the color image demosaicking process is executed to reconstruct the RGB color image from the sampled image of the color filter array. In recently years, many image authentication techniques have been proposed to protect the image integration. In this talk, we present the image authentication technique for color image demosaicking and discuss their results.
