遮挡

Model based vehicle tracking method will cause tracking drift, and can not deal with occlusion; Kalman filter based vehicle tracking method generally assumes that the motion of vehicle is uniformly linear motion or uniformly accelerated linear motion. This assumption is not appropriate for the actual movement of ...

从实验结果看，基于模型和灰度对称融合的运动车辆跟踪方法能稳定的跟踪到前方远距离车辆，能适应光照剧烈改变情况下的车辆跟踪，能处理遮挡问题，是一种有效的车辆跟踪方法。

Some important properties of affine geometry are analyzed firstly. Then two new conceptions called Extended Centroid and Affine Region Cutting are introduced.

大量实验证明，EC-ARC方法具有计算速度快，所提取的特征量稳定性高等特点，特征量对噪声干扰、照度变化和部分遮挡等具有良好的适应性。

Thirdly, improve the lighting tank structure, form a arc surface on the top of the tank to get more reflection surface. In this way, the angle of reflection avoids the shelter of the light tube and gets the most reflection.

三是巧妙改进光槽结构，让光槽顶部形成一个弧面，增强反射面；其形成的反射角减少了灯管的遮挡，使有效的反射量最大化。

Clusters of tiny insects called aphides were to be found on the underside of the leaves.

那棵树是靠着房子有遮挡的一面暖墙生长的。

A new approach for resolving occlusion problem in augmented reality is presented in this paper.

提出了一种新的解决扩充现实中遮挡问题的方法。

Experiment results show that only a small fraction of the surfaces in the complex scene are involved in the rendering phase by our algorithm, so it is not only very effective for densely occluded environments, but also suitable for mostly unoccluded outdoor scenes.

实验表明我们这个算法既适用于快速绘制遮挡率很高的场景又能快速绘制遮挡率不高但景深很大的场景。

It uses invariable hue feature to achieve adaptive blobbing, and gains target's motion state through combined estimate of blobs' motion states.

利用目标色调特征的不变性对目标色斑进行自适应分块，通过子块的运动状态联合估计目标整体的运动状态，在遮挡发生时判断被遮挡子块，并将其排除到联合推举之外。

Time the city can be observed up to 2 hours and 40 minutes; followed by the sea there is no shelter material, while other cities are in the basin, the mountain block and more is not conducive to observation; Third, the total solar eclipse occurs when the sun altitude angle Zhoushan the largest observed the best results.

全市可观测时间可长达2小时40分；其次海面上没有任何遮挡物，而其他城市大都位于盆地，山体遮挡多，不利于观测；第三，日全食发生时，舟山的太阳高度角最大，观测效果最佳。

The forms of the buildings are very natural, too: verandas are where verandas should be, halls are where halls should be, and the light draping eaves freely cover everything that should be covered.

建筑物的形式也很自然，宜廊则廊，宜堂则堂，轻巧的披檐自在地遮挡着一切应该遮挡的地方。

Firstly,we generated two depth buffers for occluder and receiver,discretizing the occluder to micro-patches;then,we calculated the depth value of shadow for each micro-patch and estimated the visibilities of them;finally,we computed penumbra extent for each micro-patch and projected soft shadow map on the scene to obtain real-time soft shadows.

首先为场景中遮挡物、接收面计算深度缓存，并离散遮挡物成许多微面；接着计算每个微面的阴影深度值，估计微面的可见度；最后计算微面半影范围，将软阴影图投影回场景中，得到实时软阴影。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
