查询词典 pixels

The proposed algorithm comprehensively considers the effects of local area average brightness of the background and space complexity on visual resolution. In order to judge whether the variance of gray is effectively percepted or not, the just noticeable difference is derived. The changes in the number of perceptible pixels between the original image and the enhanced image can be calculated by use of JND parameter. Thus quantitative results to assess the quality of enhanced images are obtained.

算法综合考虑图像局部区域的背景平均亮度和空间复杂度对视觉分辨力的影响，导出了用于判断局部灰度级跃变是否被有效感知的重要参数―临界可见偏差JND，并利用此参数分别计算出图像增强前后有效感知像素数的变化情况，从而定量地给出图像增强质量的评价结果。

Also, because we're being more economical with our pixels, we're not as pressurised to cram as much information as possible above the waterline/fold.

此外，因为我们正在与我们的更多像素经济，我们没有压力，以尽可能补习班水线以上/倍多的信息。

Also, because we're being more economical with our pixels, we're not as pressurised to cram as much information as possible above the waterline/fold.

同样，因为我们对于像素的使用非常谨慎，我们没有必要在水平线上塞满信息。

Digital pictures are often very large. For example, suppose we want to sample and quantize an ordinary television picture with a VGA video controller,so that it can be redisplayed without noticeable degradation. We must use a matrix of 640×480 pixels, where each pixel is

数字图像通常占用存储空间很大，例如，要得到没有明显的质量下降的NTSC电视图像，数字化时就必须使用640×480×8/像素的矩阵，这样就需要307 200个8位像素，共2 457 600位，并且许多情况下还要求更精确的采样。

Epipolar geometry constraint is calculated by nonlinear error propagation at initial time to accelerate the speed of stereo matching; global and local methods are integrated to extract foreground objects precisely; and only pixels on objects' contour are reprojected into 3D space to fasten the depth calculation process.

使用视觉计算实现视频增强现实遮挡处理，用非线性误差扩散模型提高了对极几何的求解精度；将全局和局部高斯核相结合，提高并加快了物体前景轮廓线的提取精度和速度；仅用轮廓线上的点进行立体匹配的方法加快了真实物体深度反求的速度。

It supports Resizing by Pixels or by Percentage or by Ratio.

它支持的像素或大小的百分比或比例。

With adjusting the epoch time and ephemeris data at the criteria of constraint Least-Mean-Square-Error, the geolocation accuracy can reach 2 pixels in the whole images; and it can be improved to approximately 1 pixel in the whole images and less than 1 pixel at nadir by considering the spacecraft attitude deviations moreover.

如果进行历元时刻和卫星轨道根数的约束最优调整，导航定位精度在整条轨道大范围内可提高到2个像元左右；如果再加入卫星姿态偏差的校正，导航定位精度在整条轨道大范围内可稳定提高到1个像元左右，在星下点附近小于1个像元。

The algorithms then estimate F, B, and for all pixels in the unknown region.

算法然后估计六，乙，并为所有像素在未知区域。

What if you don't have enough pixels for 267 ppi?

如果你没有足够的像素用于267 ppi怎么办？

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.

为了得到适合有限元分析的模型，我们必须经过如图2所示的简化步骤。
