查询词典 occlusion

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。

Human being can easily identify the road network from an aerial image by perceiving the bright-line net; the perceptual grouping is the core role in the procedure, in the local area where the occlusion exists, one focus his attention to identify the road by some contextual clues.

人能轻而易举地从小比例尺影像上整体性地感知到道路网，知觉的组织性发挥着重要的作用，这其中线条的几何与拓扑属性决定了大部分的连接感知。

The literature does not give strong support for the role of occlusion in the aetiology of TMD.

Whole liver blood occlusion technique without occluding inferior vena cava can prevent bleeding and air embolism.

不阻断下腔静脉的全肝血流阻断术既能控制术中出血，又能保证全身血流动力学稳定。

Pringle maneuver combined with hepatic veins occlusion for complicated hepatectomy is safe, and is effective to prevent dangerous bleeding and air embolism with less disturbance of systemic hemodynamics.

Pringle′s法联合肝静脉阻断技术在复杂肝切除术中既能达到减少术中出血的目的，又能防止术中肝静脉破裂导致空气栓塞，还避免了下腔静脉阻断所引起全身血流动力学紊乱，是一种更安全、有效的血流阻断技术。

Normal occlusion also has midline deviations. The asymmetry of face was larger than that of dental occlusion.

正常人群有中线偏移，面部的不对称大于牙颌的不对称。

The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, thus the occlusion contours between virtual and real objects can be reconstructed and reprojected. Further, each contour is labeled as being "behind" or "in front of" in the first two frames, depending on whether it is in front of or behind the virtual object, so the occlusion is resolved.

该算法的核心是在每一帧图像中追踪至少四个基准点，构成仿射基，进而对虚拟物体与真实物体之间的遮挡轮廓进行重建和重投影，且在前两帧图像中交互指定这些阻挡轮廓相对于虚拟物体的前后位置，从而解决了扩充现实的阻挡问题。

The contorversy on the relationship between occlusion and TMD has not yet been resolved.Most so-called TMD experts de-emphasize the importance of occlusion in the aetiology of TMD, whereas a majority of practitioners still adhere to a concept focusing on occlusal factors in diagnosis and treatment of TMD.

合因素与TMD的关系的争论仍没有得到解决，大多数所谓的TMD专家不再强调咬合在TMD病因学中的作用，然而大部分的开业医生仍然坚信着咬合因素是治疗和诊断TMD的要点的基本概念。
