查询词典 spatial coordinates

Firstly, affine covariant neighborhoods of visual words are used to verify the spatial consistency. Secondly, a set of affine transformation matrices between the corresponding covariant regions is calculated, and the matrix with the most inliers is chosen as the best matching affine transformation matrix. In this step, only a single pair of corresponding affine covariant regions is used to calculate the 6 degree of freedom affine transformation for acceleration. In the last step, the spatial consistency is verified by the BMATM.

首先通过视觉关键词仿射协变的空间邻近特征集进行初步空间关系一致性匹配；然后计算对应仿射协变区块的多组可能的仿射变换矩阵，并选择满足区块匹配最多的变换矩阵作为对象与图像之间最终仿射变换矩阵，其中，仅利用一对协变区块来计算自由度为6的仿射变换的算法有效地提高了计算速度和鲁棒性；最后通过计算出的仿射变换矩阵来精确验证对象与图像之间的空间位置关系是否一致。

A geostatistical method was put forward to analyse the spatial variability of combined heavy metal pollution in soils based on GIS. The spatial analysis showed a combined Cu and Cd pollution occurred in the research area, Cu was mainly concentrated in surface layer, but Cd had high concentrations in 0-60cm depth of soil profile. The correlation analysis revealed that the point source pollution was dominated by the pollution let-out of the smeltery.

研究首先建立了基于GIS的地统计学采样和分析方法的步骤，然后着重分析了土壤铜镉复合污染的空间变异特征和影响因素，发现研究区土壤铜镉复合污染为点源污染类型，铜在土壤中具有明显的表聚性，而镉容易迁移，在0-60cm的土层中均形成污染，同时土壤的复合污染已经在水稻籽粒中引起污染物超过食品食用标准。

The spatial niche breadth of mango anthracnose was found to have a higher index, indicating a full use of spatial resource by the mango anthracnose.

结果表明芒果炭疽病的空间生态位宽度指数比较大，对空间资源利用较充分。

Finally, NLH was selected to inverse the spatial distribution of chlorophylla concentration using MERIS fluorescence remote sensing model, and the result objectively reflected the spatial distribution pattern of chlorophylla concentration in Taihu Lake.

最后选取NFH进行MERIS荧光遥感模型的太湖叶绿素a浓度的反演，其结果客观地反映了太湖水体叶绿素a浓度的空间分布格局。

Then, the impact of spatial correlation on the combination of spatial diversity and multiuser diversity is investigated.

再次，研究了空间相关对联合空间分集和调度策略的多用户MIMO系统下行链路性能的影响。

By spatial and quantificational simulating the factors and spatial overlapping, the paper evaluated the ecological suitability and sensitivity of Qixia at county level. And, combining the method of landscape pattern optimization, the whole region of Qixia was divided into four zonings: optimizing development areas, key development areas, limit development areas, and prohibit development areas.

6运用GIS技术，通过对各生态因子的空间定量模拟与空间叠加，对栖霞市整个县域的生态敏感性和适宜性进行综合评价，并结合景观格局整体优化的方法，将栖霞市分为优化开发、重点开发、限制开发和禁止开发四类主体功能区。

Exploiting the spatial sparseness, the proposed spatial CS based approach provides a novel framework for the array signal processing.

利用空间稀少，空间政务司司长的建议为基础的方法提供了一个新的阵列信号处理框架。

A new algorithm of 3-D spatial clustering based on mathematical morphology was presented. The process of spatial data mining was given, and an artillery position selection system was realized.

提出了一个基于数学形态学的三维聚类算法，给出了空间数据挖掘过程，实现了炮阵地选取决策支持系统。

A cell is not just a well-mixed container of chemicals, but an extremely intricate system of membranes, vesicles and signaling pathways. Although a number of milestones have been built though endeavor for over a century, much is still left to discover about the spatial organization and mobility of macro-molecules (such as proteins, protein complexes, nucleic acids, signaling substances, etc.) in cells, and the spatial relationships between cells in tissues.

细胞不仅是大量化学物质的容器，也是膜、泡囊和信号传导通路组成的复杂系统，尽管通过一个多世纪的努力，细胞生物学研究取得了若干重大进展，但是关于细胞内特定高分子(如蛋白质、蛋白质复合体、核酸和信号传导物质等等)的空间组织和运动规律以及组织内细胞空间关系等许多问题的机理目前仍不清楚。
