This paper is mainly devoted to the problem of how the correlation of the adjacent coefficients in the wavelets transform and the multiscale mean values are used in image - layered coding and transporting. first, the wavelet transform is studied
本文主要研究了如何利用圖像小波變換域中的相鄰系數間的相關性、利用均值塊來實現小波系數的分級編碼和傳輸，從而實現了圖像的分級傳輸功能的問題。 -
This method takes the second generation wavelet transformation as a base, using the interrelation between transformation sample and adjacent sample to detect partial feature of the signal, and according to the magnitude of related coefficient to define the optimal pre detector and re - newer of every sample in every dimension, so as to let the wavelet be able to suit fairly the partial feature of the signal
該方法以第二代小波變換為基礎，用變換樣本與相鄰樣本之間的相關性，來檢測信號的局部特徵，並根據相關系數的大小，來確定每一尺度上的每個樣本的最佳預測器和更新器，使小波能夠較好地適應信號的局部特徵。 -
The wavelet coefficients used in the method are extracted by histogram of adjacent wavelet coefficients product
該方法採用小波系數乘積的直方圖方法提取小波系數。 -
( 4 ) designed an image authentication method of semi - fragile watermarking technique based on dwt. we transform the image into wavelet domain and group the four adjacent wavelet coefficients
（ 4 ）由於小波變換具有良好的空間?頻率局部特性以及與人眼視覺特性相符的變換機制，在新一代靜止圖像壓縮標準（ jpeg2000 ）和運動圖像壓縮標準mpeg - 4中占據了重要位置。 -
Utilizing the characteristics of the human visual system, we embed a digital signal into the average value of the four adjacent wavelet coefficients since the average value has better stability than single wavelet coefficient. this method need n ' t original image when the watermark is extracting. experiment results show the effectiveness of this method which is robust to common image process and fragile to malicious attack, i. e. this method can detect the tampered portions
因此，本文利用小波系數均值來嵌入水印，提出了一種基於小波域的圖像完整性驗證的半脆弱水印演算法，在魯棒性和脆弱性方面達到了很好的平衡，對非惡意攻擊有很強的魯棒性，而對于惡意的篡改操作有很強的識別和定位能力。 -
Therefore, the information obtained from the adjacent seismic channel can he extrapolated to the other channel by using time - frequency analysis method of wavelet
據此，利用小波時頻分析技術方法，可以把相鄰道的信息外推到其它地震道上。 -
In addition, the high and low frequency information of the adjacent channel can be transformed to the other seismic channel by taking the advantage of better similarity of subsection time - frequency analysis of seismic data, as well as the capability of learning, training and memorizing of the wavelet network
同時，利用地震資料分段時頻分析的相似性較好和小波網路學習、訓練及記憶能力較強的特點，可以較好地把井旁道的高、低頻信息轉換到相鄰道上。
