The experimental results show that the polynomial interpolation has higher accuracy and better data duplication. Therefore, this system uses polynomial interpolation to realize sub-pixel edge localization.

实验结果表明，多项式插值法具有更高的测量精度，数据重复多，所以本系统采用多项式插值法来实现亚像素级边缘定位。

In order to reducing measured errors, it is needed that the measurement system must be positioned marginally in sub-pixel level. Traditional moment methods were scarcity. In this paper, we bring forward polynomial interpolation to realize position for the object.

为了减小测量的误差，需要对被检测物进行亚像素级别的边缘定位，传统的矩方法有很大的不足，本文提出多项式插值法实现对检测物的边缘定位。

In every period, do the following operations:# For each 8*8 block, do the discrete cosine transform, then take out direct current coefficient in each block, using the transformation above for each DC coefficient, the gold stands for the code of the spread-spectrum we use when embedding the different watermark bit in different frames, after all of the watermark information which we want to embed is embedded, then do the inverse discrete cosine transformation, and store the current frame in a new file.

于是利用DCT变换域的这点重要的几何不变性，我们可以推导出一种能够抵抗几何攻击的视频水印算法，即将所需要嵌入的水印信息以127位扩频序列作为辅助，以求和值形式嵌入到DCT变换后的每个宏块的每个DC系数当中，具体嵌入和提取算法如下：根据使用的扩频序列的长度N，基于相关的嵌入器需要选取包含N帧的视频子序列，令这N帧视频子序列作为一个嵌入周期，对于每N帧视频子序列做如下的操作，#即对于每个8×8的像素块进行DCT变换，然后取出每个DCT变换后的直流分量，对于每个DC系数，做如上所述的变换，其中gold为在第k帧中嵌入第i位水印信息时使用的扩频码字值，待将所有需要嵌入的水印信息全部嵌入后，再做反DCT变换，保存当前帧。

Traditional inverse compositional image alignment algorithm compares intensity values between a template image and an input image.

传统的反向合成图像对齐算法比较的是模板图像与输入图像之间的像素值。

CV_WARP_INVERSE_MAP - indicates that matrix is inverse transform from destination image to source and, thus, can be used directly for pixel interpolation.

CV_WARP_INVERSE_MAP -表示矩阵由输出图像到输入图像的逆变换，并且因此可以直接用于像素插值。

Aiming at solving these problems,the inverse log-polar transformation based on sub-pixel interpolation is presented.

针对这个问题，文章提出了子像素反向变换算法，新算法下的变换阵图像具有良好的连续性，同时减弱了马赛克现象。

The complex function between isochromatic fringe orders and RGB gray values of the image pixels is described by BP artificial neural network.

其特点是通过BP神经网络建立图像中像素点的R、G、B颜色值与条纹级数N之间的非线性关系；可以准确地得到3级以内等色线条纹级数。

The basic idea is that using the "point" function of software UTHSCSA Imagetool to acquire the pixel values of the event in the scanned chart image and then process these arc-shaped isochronal data with algorithms proposed by us to render these data.

基本方法是利用图象软件Imagetool中的"Point"功能获取小气候自记图图象上的记录曲线上点的像素值，然后通过我们给出的算法转换成相应的数据资料。

However, if the pixels are too big the transitions appear jagged or out of focus.

但是，如果有太大的转变像素或出现凹凸不平出焦。

You can zoom in to your drawings with unparalleled precision and Scribbles will magically re-render your art so you never encounter a jaggy edge or blocky pixel.

您可以放大到您的图纸无与伦比的精度和涂鸦会奇迹般地重新使您的艺术，你从来没有遇到一个锯齿边缘或块状像素中。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
