The thesis also gives the optimal threshold of bits resume in the watermark extraction in details
水印的檢測過程需要比特恢復，本文根據最小錯誤概率準則，詳細推導了水印的比特恢復閾值。An improved adaptive image watermarking algorithm based on block dct and arnold shuffling is proposed : with shuffling techniques in image watermarking, you can not only prevent illegal users from riddling the content of the images, but also disperse the distributing of error bits in order to enhance the robustness of watermarking
提出了一種改進的基於分塊dct （ discreteconsinetransform ）變換和arnold變換的自適應圖像水印演算法:本文將信息置亂技術用於圖像水印中，一方面可以使非法使用者無法破譯圖像的內容，另一方面可以盡可能的分散錯誤比特的分佈，從而提高數字水印的魯棒性。Experimental results show that the proposed techniques have good imperceptibility and can survive of common image processing operations and jpeg lossy compression with high robustness. the second one considered the watermarking system as a special digital communication system and introduced the ecc as channel coding technique. by using the turbo coding technique, we are able to reduce the watermark bit error rate and improve the robustness of the watermark so as to make counterfeiting attacks more difficult
本文在保證水印不可見性的基礎上和載體圖像的允許降質范圍內，利用rbf神經網路技術實現數字水印信息的最大強度嵌入以增強數字水印抵禦各種惡意攻擊的穩健性;在通信論和信息論模型基礎上，引入ecc （差錯控制編碼）技術降低水印的誤碼率，使得提取水印信息更加可靠，使可能的水印攻擊變得更加困難，從而獲得更好的水印穩健性和可靠性。A digital products copyright protection system model based on digital watermarking has been proposed as the final result of this part. in the robust digital watermarking systems part, a robust watermarking embedding mechanism and a watermarking detector based on minimum error rate are presented
在數字水印系統部分，本文提出了基於局部區域統計量的魯棒數字水印的嵌入模型和基於最小錯誤率的水印檢測模型，並進行了理論推導。分享友人
