When embedding watermark it archived the purpose of self - adaptation control on watermark imbed quantity according to different coefficients
從而在嵌入水印時，達到對不同的系數所在塊進行自適應地控制水印嵌入量的目的。 -
A 4x4 optical fiber network embedding in composite materials is designed to determine the feasibility of the self - diagnose program. finally, the method of self - repair using hollow optical fiber filled adhesive is put forward. two samples are made to study the performance
在此基礎上設計了一個可以實現損傷診斷的3x3空心光纖網路構成的智能結構自診斷系統，並按照小型化、經濟化等要求完成了光源的選擇、發光和接受電路的設計、耦合介面和數據採集系統的研究。 -
This method has many advantages compared to the latter and is testified by many images. ( 2 ) because fractal coding has the characteristic of high compression ratio, this thesis designed a spatial self - embedding watermarking technique. after self - embedding, it can detect any changes to a watermarked image as well as localizing the areas that have been tampered
（ 2 ）鑒于分形圖像壓縮具有很高的壓縮比且重構圖像效果好的優點，本文利用分形壓縮實現了一種空域自嵌入水印演算法，不但能對篡改區域進行有效定位，而且具有修復功能。 -
If possible try to recover portions of the image that have been tampered without accessing the original image. in the past, several techniques and concepts based on data hiding or steganography have been introduced as a means for tamper detection in digital images and for image authentication - fragile watermarks, semi - fragile watermarks, and self - embedding watermarks. the research of this thesis mainly includes self - embedding and semi - fragile watermarks
目前用於數字圖像完整性驗證及自修復的數字水印方案主要有完全脆弱性水印、半脆弱性水印、自嵌入水印等，本文主要研究自嵌入及半脆弱數字水印，分別從空域及變換域角度詳細分析當前國內外現有的各種演算法，指出其不足之處，並提出了相應的改進演算法，實驗結果表明本文演算法的有效性與實用性。 -
We propose several watermarking techniques after analyzing other watermarking methods detailedly. the main contributions can be summarized as following : ( 1 ) based on previous work, we proposed an improved spatial self - embedding watermarking technique. we save the quantized dct coefficients using group encoding while not using bit matrix which restricts saving bit length of each dct coefficient
本文的創新之處總結如下： （ 1 ）提出了一種改進的具有修復功能的空域自嵌入水印演算法，利用分組編碼保存量化后的dct系數，改善了修復效果，克服了以往使用位圖矩陣的不足，具有通用性與實用性。 -
It is also possible to recover portions of the image which have been tampered. experiments on real images verify the effectiveness of the proposed technique. ( 3 ) since the current self - embedding watermarking techniques are too fragile to resist noise or jpeg compression, we proposed a self - embedding method based on jpeg images which plays an important role in current internet environment
（ 3 ）由於現有的空域自嵌入水印演算法大多數是對位圖圖像嵌入水印，在抗jpeg壓縮方面顯得過于脆弱，因此本文實現了一種直接對jpeg圖像進行自嵌入的數字水印演算法，具有檢測篡改及修復功能，對于當今網路時代來講具有重要意義。 -
In chapter l, we in - troduces self mappings on an interval, the roots of the functions, functional equations and the embedding flow
對迭代的研究涉及線段上的自映射，迭代根與迭代函數方程，迭代根與嵌入流等問題。
