pixel block 中文意思是什麼
-
Conclusion r1 represent pixel - value of original image range block, r represent mean - value of original image range block, d represent mean - value of original image domain block, d1 represent pixel - value of resumptive image domain block, d represent mean - value of resumptive image domain block. superior perfermance of resumptive image range block is obtained as compared to conventional creative function by one iteration, that is,
） ， d _ i （ i = 1 ， 2 ， … ， n ）分別為某一恢復圖像定義域塊的均值和每一像素的像素值，我們用傳統的和改進的生成函數分別進行一次迭代，則用改進的生成函數進行迭代的恢復圖像每一值域塊的效果較好，即： -
For each block, the mean and variance values can be seen as the pixel group properties
該方法不但考慮了像素的屬性，還考慮了像素群的屬性。 -
This paper completely pay respect to the two characters in the ridge ' s binarization step. and in this paper, we using the information of the pixel ' s grads which in the fingerprint ' s digital image and propose an approach that we can confirm the block ' s orientation
本文在脊線二值化過程中充分考慮了這兩個特性，並且利用指紋圖像中點梯度的方向信息，提出了用相位編組法確定塊方向，然後基於塊方向進行方向濾波，收到了較好的效果。 -
In construct to current schemes proposed so far which either operate on a subband or a block base, the scheme in this thesis is based on pixel
不同於現有dwt演算法基於一個子帶或者基於塊來操作，本文的演算法是基於象素的。 -
The standard is designed to give a new technical solution for a broad range of applications, such as very low bit rate conversational services and entertainment quality broadcast, interactive video - on - demand services etc. for the enhancement of the coding efficiencies, the new standard adopts new tools as following : multiple reference pictures, variable block - size with seven block sizes in motion prediction, quarter - pixel accuracy for motion vector, short word - length integer transform, context - adaptive entropy coding and loop filter deblocking
H . 264 / avc標準支持從低帶寬、高誤碼率的無線移動視頻通信到高帶寬、低誤碼率的有線視頻廣播等多種應用，因此，日益受到業界的關注。為了實現更高的編碼效率， h . 264 / avc標準採用了很多新的編碼技術，如多參考幀預測、多尺寸編碼塊模式、 1 / 4像素精度運動矢量、整數變換量化、基於內容的熵編碼、新型幀內預測、去除方塊效應的濾波器等。 -
One watermark pixel is embedded many times ( chip rate ) into different dct coefficients in same block
本文利用多次嵌入技術，在多個dct域的多個系數中嵌入相同的一位信息。 -
This protocol is implemented based on lsb watermark technology. its highlight points are : the verification and authentication data are embedded into the images " data, any changes of pixel values and changes in image size due to scaling or cropping as well as block swapping in images or corresponding block swapping between images can be detected and located, logo image is unnecessary
本文提出的基於數字水印技術的數字圖像完整性與身份驗證技術綜合了信息安全技術中有關消息完整性與身份驗證的方法與數字水印技術，並充分考慮到了數字圖像的特殊性，提出了兩種協議模型：無仲裁協議模型與有仲裁協議模型。 -
