像素

However, if you want to make large prints or special duplicates, then you should get a camera with at least 5 or more megapixels.

但是 ，如果你想进行大量打印或特殊重复，那么你应该得到的相机，至少5人以上百万像素。

The advantage here is that there are no artifacts associated with dropping pixels or duplicating them.

这样做的一个优点是像素的丢失和复制不会造成人为的影响。

A new method was given for determining the eye movement in a video-oculography system, where the centroid method was used to get the initial position of eye center, a edge filter was used to obtain all the boundary of the pupil, then a ellipse fatting was used to determine the accurate position of the eye center.

本文提出了一种全自动确定眼动平动的新方法。首先用形心法确定瞳孔的初始位置，再用亚像素边界算子提取瞳孔边界，并用带自动优化功能的椭圆拟合最终确定瞳孔的精确位置。

The algorithm first divides the scene into certain layers that do not intersect each other by light's frustums in light space, and generates one shadow map for each layer to ensure that any shadow map does not have the same sample points. Then a faster synthesizing scene shadow method, which avoids operations of pixel layer determination, is given to improve GPU's efficiency.

在光源空间中，利用光源视锥体将场景划分为不相交的多层区域，利用GPU为各层生成阴影图，以确保场景采样点不在多层阴影图中重复出现；同时给出了一种快速综合场景阴影效果的绘制方法，通过避免判断像素层次的操作提高了GPU的利用率。

For the same reason, the illuminated parts of the pixels are smaller and further apart than they could be, so the image is fuzzier.

基于同样一个原因，像素被照亮的部分就变得比本来面目更小并越加分离，因此图像也就变得模糊不清。

Light, represented by the rainbow at the top of the image, impinges on photodiodes with the CCD pixels.

在图象顶部以彩虹代表的光，与CCD像素的发电二极管紧密接触。

DCT transformation and PCA transformation keep down the main information of lip region in gray image while reduce the dimension rapidly.Lip movement is highly correlated with audio signal and speech content can be revealed througn lip-reading.

在特征提取方面，除了唇分割后直接提取的几何特征外，利用DCT变换和PCA变换后的系数作为唇动像素特征，这种方法可以在达到降维目的的同时保留原有特征的主要信息。

Whether you're using mipmapping or not, you should never use "nearest" filtering, which causes texture swimming artifacts when textures are minified.

不管你是否使用&mipmaps_多精度纹理&都不要使用&nearest_邻近点&采样，它会在纹理被缩小时产生像素漂移。

What's more, modulating the voltage level applied to the pixel allows many discrete levels of brightness.

此外，对施加到像素点上电压高低的调制也可以实现对多种亮度级的显示。

The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.

运用已标定的双目照相机拍摄立体图像对，进行足部整体视差估计；在对立体图像对进行自动预处理后，采用非接触式的信息采集技术，运用基于复小波的相位相关技术对足部表面进行亚像素级小区域频域匹配，考虑顺序匹配约束、连续性约束和相关性约束条件，重建足部密集三维点云信息，并自动拼接不同角度点云生成相应的足部三维模型；对其归一化后，提取其高阶矩向量进行比对，为后续的三维鞋楦设计提供必要信息。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
