The management and quality analysis of the primitive images have been analyzed and studied in this paper, of which the content and structure are as follows:Firstly, the developing background and the meaning of the management and quality analysis of the primitive image, as well as the trends of the management and data quality of the image database studied both in and out of our country, have been discussed in detail.Secondly, the developing direction of the technology of the remote sensing image and the importance of the remote sensing images in the field of economy nowadays have been analyzed systematically. And it is pointed that the primitive image with the elements of interior and exterior orientation will become more and more important as a sort of image production.Thirdly, the hierarchical structure of database, especially the SQL Server adopted in this system, has been deep studied and analyzed in the aspects of Applying Program Interface, Internet Data Connector and ActiveX Data Object.Fourthly, the methods of assessing the quality of the remote sensing image have been put forward in the terms of geometry, construction and the integrality of the assistant information.Fifthly, the model of propagation of errors of the precision of the ground coordinates has been calculated in the steps of inner orientation, spatial resection and answering based on the deep analysis of the principles and processes of inner direction and space resection, which have also been experimented and analyzed in term of numerical value.Finally, the total design and the idiographic realization of the sub-modules have been introduced in detail, based on which the design and development of this system are realized in combination with the program languages such as VB6.0, VC6.0 and SQL.

An automatic algorithm was used in the analysis to identify clusters of groupings of patients. We used the classical unsupervised clustering method called the Iterative Self-organizing analysis technique of DATA analysis originally introduced by Ball and Hall.25 The technique allows the splitting and merging of clusters while trying to find the "best" configuration. It therefore, requires very little a priori knowledge about the data and predefining the possible number of clusters or groups is not required. The range of possible minimum and maximum number of clusters within which the algorithm can search for an optimal configuration was determined by a procedure called the chainmap which reorders the multidimensional data in the form of a 2D distance map.26 A patient vector is randomly selected and its nearest neighbor is identified as that with the shortest distance between the 2 patients' vectors.

使用自动算法来分析鉴别患者组的聚类，我们使用经典的最初由Ball和Hall提出的的非监控聚类方法，该技术允许在寻找&最佳&形态使对聚类进行拆分和组合，他不需要对数据专门的知识和对聚类或群的可能数量进行预设，在聚类可能的最大和最小范围内，算法可以通过一个叫Chainmap的程序寻找最理想的形态，该程序记录了来自2D距离图的多维数据。
