SRDM:支持基于内容检索的图象数据库超关系数据模型

SRDM:A Super Relation Dais Model Supporting Content-Based Image Retrieval

数据模型是实现基于内容查询的图象数据库的基础。在这篇论文中，笔者引入了一种按内容进行图象查询的图象数据库数据模型－ＳＲＤＭ（Ｓｕｐｅｒ Ｒｅｌａｔｉｏｎｌ Ｄａｔａ Ｍｏｄｅｌ）。该模型将可视特征、空间特征、语义特征等看作超属性，既充分利用了关系数据库的优点，同时又考虑了图象数据的特点，因而能较好地支持基于内容的图象数据库的查询。

Data model is a basic component to design image database supporting content-based image retrieval. In this paper,a new data model for image database-SRDM is introduced. As the model regards visual features, spatial features and semantic features as a whole super attribute, which both makes full use of relation database and takes count of the features of image data, it supports content-based retrieval in image database.
