In our research, A new calcium parameter which utilized three-dimensional information of all calcific pixels in EBCT scanning images, had a higher reproducibility.

本研究新设计的钙化参数由于利用EBCT扫描图像上所有钙化象素点的三维信息，因此具有较高的可重复性。

Consumer-friendly package. The Z700 offers a smooth filmlike picture, very quiet fan noise, and no pixelation or screendoor effects from a normal viewing distance.

消费者友好的封装。Z700提供了一个平稳胶片感画面，风扇噪音非常安静，没有象素或从一个正常观看距离纱窗效应。

The purpose of the "low resolution cinema" project is similar to the Geometrical Abstraction movement, which was active in the beginning of the 20th century, and who based their work on a non-objective practice while ejecting the illusionistic practices.

&低象素电影&项目的目的与在19世纪初很盛行的几何抽象移动的理念是相似的。

There is spatial correlation between the neighbored pixels , so there is the adjacent gray value .

大多数图象具有空间相关性，绝大部分相邻的象素点具有相近的灰度值。

The aim of the watershed transform is to search for regions of high intensity gradients that divide neighbored local minima .

能量函数定义如下：〓clique主要是一些集合点，这些集合依赖于属于clique集合C的象素正如第四章中方程4.26。

There is very little digital noise, virtually no pixelation, no overdriven sharpness, no overly brilliant or blown out highlights.

很少有数字噪声，几乎没有象素，没有过驱动锐度，没有过于辉煌或被炸出亮点。

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。

Quantitative description and 3-D reconstruction of heart vessels are based on thinning vessels to skeletons with only one pixel width. But vessels extraction from angiogram decides the accuracy of vessels skeletonization.

利用心血管造影图像定量描述心血管病变和重建三维心血管，首要任务是将造影图像中的心血管表述成单个象素宽的心血管骨架，而心血管的提取又是心血管骨架提取和决定其提取准确性的关键。

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。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
