Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

By analyzing the characteristics of the boundary pixels to formulate a boundary pixel extraction operator, the operator need only calculate up to 4 pixels neighborhood pixels, is efficient, fast, he can direct the use of binary images are extracted as the boundary pixel, are single-pixel wide border.

通过分析边界象素的特征，归纳出一个边界象素提取算子，该算子最多只需要计算象素的4邻域象素，运算量小，速度快，运用他能直接提取出二值图象的边界象素，得到单象素宽的边界。

In order to mine the structure difference of the chinese and english characters,the gradient information of the pixel based horizontal and vertical stroke vector,gradient orientation correlogram and the relative gray information of the location correlation pixels based census transform histogram are used,they can be robust to illumination,noise and resolution and so on,and can be applied to camera-based images.

为了能够很好地挖掘中英文字符之间的结构差异，提出采用基于象素梯度信息的水平垂直笔画向量和梯度方向相关图，以及基于位置相关象素的相对灰度信息的Census变换直方图，它们对光照、噪声以及分辨率等都具有良好的鲁棒性，可以应用于基于相机的图像。

When we are designing a webpage, sure meeting considers the issue of resolution, science and technology develops what we use normally now is the resolution of 1024*768 and 800*600, now the width that is used to 778 to resemble element is more very on the network, often make whole webpage very depressive below the resolution of 800, have kind of airtight feeling, actually this width is the widest width that points to the webpage on the resolution in 800*600, do not represent optimal visual sense, might as well the elephantine element that tries 760~770, no matter be in 1024 still can achieve below the resolution of 800 relatively the visual effect of beautiful.

我们在设计网页的时候必定会考虑到分辨率的问题，科技发展到现在我们通常用的是1024*768和800*600的分辨率，现在网络上很多都是用到778个象素的宽度，在800的分辨率下面往往使整个网页很压抑，有种不透气的感觉，其实这个宽度是指在800*600的分辨率上网页的最宽宽度，不代表最佳视觉，不妨试试760~770的象素，不管在1024还是800的分辨率下都可以达到较佳的视觉效果。

A pixel shader performs per-pixel processing such as texture blending, lighting model computation, and per-pixel normal and/or environmental mapping.

PS 执行逐象素处理，比如纹理混合，光照模型计算，逐象素法向和环境映照计算。

Pel'.'' path to the dimension on the direction of the line progression.

象素陈列在象素走向方向上的尺寸与在行进向方向上的尺寸之比。

For drawing the parameter curve by point to point it orde to the parameter t's step length of increased make the progress range of the curve can not large than the length of one pels, otherwise the curve may step over one middle pels and skip one point that it should be on the curve.

要逐点地生成参数曲线，就要求参数t每次增加的步长要使曲线前进的幅度不得超过一个象素长度，否则有可能跨过一个中间象素而产生断点。

But after using the above methods, picture element density's enhancement will become a big conditionality, and cannot be easy achieved high integration.

但采用以上方法，对象素点密度的提高有较大的制约性，不能较易实现象素点的高度集成。

The improved pixel lateral histogram algorithm was used to extract the centre of crop row. The infield adaptability of the pixel lateral histogram algorithm was enhanced by subsection computation of pixel lateral histogram.

根据条播作物行距基本恒定、作物成行排列的位置特征，利用改进的象素位置直方图法识别作物中心行，通过分段统计象素位置直方图，有效地提高了算法的田间适应度。

The style in the example below tells the browser to display a 14 pixels Verdana font on the screen. But if the page is printed, it will be in a 10 pixels Times font.

下面例子中的样式告诉浏览器在显示屏幕上使用14象素Verdana字体，但在打印时字体就变为10象素的Times。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
