摘要


本篇實驗我們設計了一個可逆式資訊隱藏之無損可見式浮水印方法,此法可以抽取出原 本的浮水印以及得到原本的圖片.我們利用reversible data-hiding的方法在非浮水印區隱 藏資訊,在浮水印區我們用黑白浮水印來取代原本的LSB. 實驗結果顯示,我們放上浮水印和隱藏資訊之後的圖片,和前人的研究相比,有較好的 PSNR,且可以清楚的看到浮水印.

並列摘要


In our research, we design a lossless visible watermarking scheme whichcan extract the original visible watermark and recover the original hostmage losslessly. Our research based on reversible data-hiding techniques to embed secret data at unwatermarked area. At watermarked area, we replace the LSB7 by halftone watermark. The experimental result shows that PSNR values of watermarked images from our scheme are better than ones obtained from previous schemes; also we can see the watermark clearly.
