High
This paper presents a clustering approach
which estimates the specific subspace and the intrinsic dimension of each class. Our approach
adapts the Gaussian mixture model framework to high-dimensional data and estimates
the parameters which best fit the data. We obtain a robust clustering method called High-
Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images
in a probabilistic framework. Experiments on a recently proposed database demonstrate the
effectiveness of our clustering method for category localization.

STK
针对STK(Satellite Tool Kit)软件在军事任务可视化仿真领域中的广泛应用,为充分挖掘
其显示潜能,重点解决了影响其三维场景构建的瓶颈问题,即三维场景数据格式的转换和数据的获取
优化。在分析构建STK 三维场景所需要素及其作用的基础上,分别对地形、地表纹理、三维模型和GIS
等四类数据格式进行分析,并利用多种辅助软件,系统地提出了由较通用格式数据向STK 所支持格式
数据的转换方法,以及在对各类原始数据的获取和转换过程中出现的问题进行处理的优化方法。最后通过实例验证表明该数据格式转换方法和数据优化方法行之有效,三维场景显示效果逼真。(STK (Satellite Tool Kit) software widely used in the field of military tasks, visual simulation, to fully tap its display potential, focus on resolving the bottlenecks that affect the construction of the three-dimensional scene, 3D scene data format conversion and data Get optimization. On the basis of the required elements and their role in the analysis of building STK three-dimensional scene analysis, respectively, of the four types of terrain, surface texture, three-dimensional model and GIS data format and use a variety of assistive software, the system proposed by the more common format The data support the format of the data to STK conversion method, as well as access to various types of raw data and conversion process issues deal with the optimization method. Finally, an example to show that the data format conversion method and data optimization method is effective, realistic three-dimensional scene display.)

减少模糊规则数,易于提取模糊规则,适合于交通状况复杂的城市交叉口交通信
