基于内容的航空图像检索系统分析与设计

Aviation Image Searching System Analysis and Design Based on Content

基于内容的图像检索根据图像、图像的内容语义以及上下文联系进行查找,以图像语义特征为线索从图像数据库中检出具有相似特性的其它图像.因为图像的规模一般要大于纯粹的文本信息,因此,基于内容的图像检索在检索的速度和效率上要求更高.航空图像的检索是目标数据库应用的重要方面.对基于内容的图像检索理论进行了研究,给出了图像检索的基本原理和该检索系统的组成和初步构建.

On the content diagram index, according to content diagram language, diagram resemble righteousness and context contact proceed to seek, with the diagram resemble language righteousness, the characteristic resemble database from the diagram as the clues has the other diagrams with the characteristic resemblance. Because scale of diagram generally wants the more information of text, therefore, according to the contents resemble the index on the index＇s speed requests higher efficiency. Aviation image searching is an important fact of target database applying. This text discusses the theory of searching based on content, proves basic principle and system frame.
