基于内容检索的图象数据模型的设计

Design of image date model content based on image retrieval

为了解决图象数据有效查询问题,设计具有基于内容图象检索功能的面向对象数据模型,作为数据库的引擎,分析了图象数据库的系统结构,根据这个结构分别对结构层和操作层建模,完成数据模型层的概念和逻辑设计,实现了一个支持基于内容检索技术的图象数据库系统。可视性好,对图象资源可以进行有效的管理和检索。

For efficient image retrieval,the object oriented image data model,based on image retrieval is designed and embedded into the imaged database,a product of object oriented multimedia database system.The image database system structure is analyzed according to this structure the structure level and the operation level are modeled separately and modeling,completes the data model level the concept and the logical design are completed,realizing a support based on the content retrieval technology image database system.The system can carry at effective management and the retrieval for the image resources.
