The main conclusions are the following:1 It is a effective means that making use of the high resolution remote sensing imagery has quickly and dynamically investigated and monitored the land use type ofRed Water River, and has carried through the four grades of classification, and its result has achieved the precision requirement of the minimum area of obvious land use type (cultivated land, field, economic forest) less than 9 pixel of imagery, area precision 9~27 pixel and 0.33 hectares.2 It is a high-efficient and feasible means that making use of the digital managing technology of wave band merging, precise geometry correction, imagery merging, imagery strengthening, imagery cut out and inlay, and making the orthograph, etc, and observing on the spot to data analysis, it has carried on people-computer interactive screen translating to the remote sensing imagery data of high resolution by using many kinds of geographical information systems soft ware.

In our article looking at XBOX 360's graphics processor, the ATI Xenos, we saw the first implementation of a unified shader core, whereby both Pixel Shader programs and Vertex Shader programs are executed over the same hardware block, as opposed to having separate vertex and pixel shader engines – its expected that ATI's PC graphics accelerator for DirectX 10 will also feature a unified shader architecture and NVIDIA are now talking about such a platform (having initially said that they believe separate discrete units would be more optimal in terms of processing performance).

ATI Xeons， XBOX 360的图形处理器，第一块采用统一着色核心的产品。为什么顶点着色程序和像素着色程序都在同一硬件上完成，而不是分别采用顶点着色引擎和像素着色引擎？预期ATI对应于DirectX 10的PC图形加速器也将以统一着色架构为特色。NVIDA现在也在研究这样的平台（起初声称分开的离散单位在处理表现上会更理想^。^）。

Eight 3×3 Kirsch direction templates are convoluted with a SAR image respectively and the maximum of convoluting results is used as the edge strength value of the central pixel in the window. The output gray level of the central pixel is the weighted average of gray levels of its eight neighboring pixels, and the weighting coefficients are corresponding edge strength values.

该方法利用8个3×3的Kirsch方向模板分别与SAR图像进行卷积运算，取其中的最大值作为窗口中心像素的边缘强度值，中心像素灰度值的滤波输出为它的8个邻域像素灰度值的加权平均，加权系数为每个像素的边缘强度值。

The filter, which is a convolving kernel as a function of the pixel under consideration, is applied only to a pre defined neighborhood of the current pixel.

实验表明，该方法对合成及自然彩色图象均有较好效果，能够方便快捷地得到图象的边缘。

With the premise of assuring pixel immixing model, wether good or bad it is, the choice of endmembers directly influence accuracy of pixel unmixing.

在混合像元分解模型确定的前提下，端元组分选择的优劣直接影响混合像元分解的精度。

In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering.

在本论文中，我们提出一个高频率倍数的全数位式锁相回路，此电路可应用於视讯系统中的时脉产生器，其主要功能是接收显示卡发出的水平同步讯号，并依据使用者设定的萤幕解析度，产生高频像素时脉来撷取视讯讯号资料，取样点的稳定度直接影响到显示画面的品质，若是像素时脉不稳定，则显示画面会闪烁或抖动。

The first pixel includes a first pixel driving circuit that overlies the substrate and includes a first electronic component.

所述第一像素包括覆盖在所述衬底上方的第一像素驱动电路，并包括第一电子部件。

One of its main purposes is to ensure that important widths and heights are respected throughout the whole font (for example, it is very often desirable that the "I" and the "T" have their central vertical line of the same pixel width), as well as to manage features like stems and overshoots, which can cause problems at small pixel sizes.

这主要目的之一是为了确保整个字体中，重要的宽度和高度能够一致。例如对于字符I和T来说，它们那个垂直笔划要保持同样象素宽度。另外，它的目的还有管理如stem和overshoot的特性，这在小象素字体会引起一些问题。

In order to extend the effect and security of image encryption algorithm.An image encryption algorithm is presented based on three-dimension chaotic system and bit-computation.The permutation sequences and binary sequences are generated using three-dimension chaotic system.Firstly,the image is pretreated using chaotic system and permutation transformation,then the pixel's gray value's bit sequences are permuted using the permutation sequences generated before,at last,the pixel's gray value's bit sequences are computed by using XOR operating and the binary sequences.

为了改进图像加密算法的安全性和效率，提出了一种基于三维混沌系统和位运算的数字图像加密算法，利用三维混沌序列的坐标分量分别产生置换序列和二值序列，在对待加密图像进行预处理的基础上，先应用混沌置换序列对预处理的结果图像进行基于灰度值位序列的置换操作，然后再应用产生的二值序列对结果图像的灰度值位序列进行位异或加密运算。

In this paper, we presented theoretic analysis and experiment research in pixel resampling, pixel reassigning and weight coe fficient selecting.
