查询词典 pixels

Vertices, triangles, and pixels thus recirculate through the grid rather than flowing through a pipeline with stages of fixed width, and allocation of the pool of processors to each shader type can dynamically vary to respond to varying graphics load.

顶点、三角形、象素循环而不是以固定的宽度通过管线，以及为每一个着色器分配一个池来动态的响应不同的图形加载。

After analyzing Tian and Alattar algorithm, a novel lossless information hiding method based on integer linear transform was proposed. The near character of pixels could be analyzed. After the less distorted revisable vector was transformed by integer linear transform, hidden information was embedded by pair-check modulation.

在分析Tian和Alattar隐藏算法的基础上，提出了一种基于改进整数线性变换的无损隐秘传输方法，通过分析可修改矢量区域象素的邻近相关性，选取出对图像质量影响较小的可修改矢量，进行整数线性变换后再嵌入信息。

Secret information embedded asymmetrically made the correlative degree of adjacent pixels sequence of carrier image reduced, especially the correlative degree of some local image may saltate. This phenomenon enhanced the risk of secret information being detected.

隐藏信息的非均匀嵌入使得载体图像的相邻像素序列相关度降低，而且图像局部有相关度突变的现象，增大了隐藏信息被检测到的风险。

Two construction methods for fewer views from limited range—ART and SART are studied, and simulated a physical fields views whose variation of deflection is equal to double-Gauss function, and then reconstructed it, and still analyzed the accuracy of the reconstruction methods.After study and analysis on the theory of ART and SART, and after analysis the properties resulted from their theory root cause, A modified simultaneous algebraic reconstruction method is presented, which is based on ART, this method takes into account both the pixel itself and the pixels close by it which are crossed by the same ray.

论文研究了两种有限投影方向的非轴对称场的CT重建算法——代数重建法和联合代数重建法，并用VC++程序模拟实现了折射率分布为双高斯函数的场的正向投影及重建过程，并对所用算法的重建精度进行了分析。

With rotational invariance of circle, image was divided into different sectorial sub blocks in polar coordinates, and the sum of regional pixels was taken as sector eigenvalue. Then a normalized feature space by norming sector feature set was got.

以圆的旋转不变特性为基础，在极坐标下将图像分割为不同的扇形子块，并将各子块区域灰度和作为表示扇形子块的特征，然后对子块特征集进行归一化，所得的归一化扇形特征集作为特征选取的空间。

When the viewpoint is changing quickly, the rendering algorithm ignores some details of the diffuse component, otherwise the scene is rendered more precisely. The Specula highlight is dependent of the viewpoint, it must be processed in real time. We present an algorithm to get rid of the area that does not contain specula highlight quickly and calculate only the area that contains the specula highlight. In order to calculate the specula reflection and refraction component, we presented a new raytracing algorithm based on the environment map transformation. The environment maps are constructed at the sample points of the scene in the preprocessing phase. We add depth information in the environment maps and generate the exact reflection and refraction intensity with the transformation of a few pixels.

对于表面光亮度漫射分量，由于它与视点无关，可以把面片按照光照细节的分布预剖分成层次结构，然后在实时漫游时根据场景变化的快慢决定绘制的细致程度；对于镜面高光分量，由于它与视点有关，必须实时处理，我们提出了一种快速高光裁剪算法，通过简单测试，去除那些不包含高光的区域，只处理包含高光的区域；对于镜面反射分量和折射分量，我们提出了一种基于环境映照变换的快速光线跟踪算法，预先在场景的离散采样点处建立环境映照，然后根据入射点的位置，把邻近采样点处的环境映照上相关象素处的可见点变换过来，求取反射分量和折射分量。

The preparation of 256×1 pixels uncooled infrared detector as well as some infrared thermal images is also reported.

此外，还介绍了256×1线列铁电薄膜非制冷红外探测器的研制及部分成像结果。

In this dissertation, we first adopted many methods to determine the number of endmembers, then a method by combining the a prior knowledge of hyperspectral data into nonnegative matrix factorization was proposed to unmix hyperspectral images when there are no pure pixels existing in data.

在本文中，我们首先采用多种方法对超光谱图像端元个数的确定进行分析，然后将超光谱图像的先验知识加入到非负矩阵分解中，对纯像元不存在情况下的超光谱数据进行混合像元分解，实验结果表明本文中提出的方法是有效的和可行的。

We live in a culture dominated by pixels, increasingly unmoored from corpor-eal reality.

我们生活一个被像素所控制的文化中，与现实越来越远。

Also, there is a tendency for the voltage at a row-column intersection to "bleed" over into neighboring pixels, partly untwisting the liquid crystals and blocking some light from passing through the surrounding pixel area.

此外，行-列交点处的电压也容易泄露到相邻的像素点上，这会在一定程度上造成周围区域像素的液晶变得不透明，阻碍光线的通过。

Chinese traditional virtue is humility and wariness,the compliment and praise to the others should be declination

中国人的传统美德是谦虚谨慎，对别人的恭维和夸奖应是推辞。如

We bought this house on the never-never.

我们以分期付款的方式买下这座房子。
