  4. Based on the classification of images, this paper gives out four digital image steganography techniques which have good conceal effect, including low - three - bits hiding strategy, odd - even of hypo - low bit hiding strategy, deviation of adjacent - field hiding strategy and self - adaptive deviation of adjacent - field hiding strategy. on digital watermarking aspect, this paper gives two blind watermarking strategies which have good conceal effect and high robustness, they are single - watermarking strategy based on minimal - value exchanging and multi - watermarking strategy which hides the same watermark copy on the different parts of an image

  5. The main contributions of this dissertation are : a novel detection strategy in blind image watermarking algorithm generally, the traditional detection strategy corresponding to embedment model i = i + aw has its limitation. first, we treat the watermark information as noise for an image and expand the noise before detection. then, we find the corresponding data in the frequency - domain and adjust them according to our relative minmum principle

    為了解決這一問題，我們將嵌入水印圖像中的水印信息看作一種噪聲，在提取水印前，利用降噪方法得到原始圖像的一個逼近，通過和待檢測圖像的比較，得到含有水印信息的噪聲，再將這種噪聲信息進行放大，最後利用局部最大的編碼原則將水印恢復出來；將改進的水印提取模型應用於基於fourier - mellin變換的盲水印演算法，解決了由於插值和多變換造成誤差積累而造成很難提取水印這一問題。
