【摘要】 我国是世界上的建筑卫生陶瓷生产大国，其中瓷砖是应用最为广泛的一种室内外装饰材料，它的种类和花色也是丰富多样。但目前大部分陶瓷企业都是各自研发设计陶瓷新产品，没有形成统一协作，信息化程度不高，特别是瓷砖表面图像的设计资源不能共享。由于瓷砖的用量大，要求的花色多，表面装饰图像的设计是瓷砖生产企业的一个重要部分。如果能建立一个瓷砖表面图像库供客户浏览查询，则可作为设计新图像的参考，进而形成各企业间的共享来节省时间和开支，也可为装饰设计选材提供方便。针对图像库的图像检索经历了基于文本的图像检索和基于内容的图像检索两个阶段，本课题在实现基于文本检索的基础上，重点完成了基于内容的瓷砖图像检索系统，并对结果进行相关反馈来提高检索的准确性，以满足实际生产的需要。本课题主要完成了以下几个方面的研究和实现工作：首先，概述了基于内容的图像检索技术研究和发展现状，并详细介绍了本系统涉及到的一些理论知识。其次，根据瓷砖表面图像的特点，确定实现基于内容的图像检索技术的具体方法，并针对瓷砖表面图像的自身特点采取基于纹理特征进行图像分类的方法来优化检索。最后，采用Microsoft公司开发的Visual Studio.net 2003工具中的C#语言，结合sql server 2000数据库，采用面向对象的程序设计(OOP)方法编程实现实际系统。系统主要完成以下几个方面的功能：图像预处理；图像特征提取及入库；图像类别管理；图像管理；用户管理；图像浏览；图像检索；检索结果反馈；实验结果证明了本系统所采用方案的可行性和正确性，具有较大的实用价值。更多还原

【Abstract】 Our country produce a great deal of the building and sanitation ceramic, especially the tile which is the popular material of room inner and outer ornament, it’s class and color are very abundance.But at present most ceramic enterprise each design new product, havn’t form a unite for collaboration, information degree is very low, especially the designing resource of tile suface picture can’t share. As the tile’s dosage is very large, and need lots of colors, designing of surface picture become one of the important part of tile’s enterprise. If founding a database of the tile surface picture for user browsing and querying, reference for designing new picture, share resource among tile enterprise to save time and expense, also could offer convenience for choosing ornament design material. The image retrieval on the database come through two phase: the retrieval based on text and the retrieval based on content. This project achieve the retrieval based on text at first, then stressed achieve the system of content-based image retrieval. For heightening the rate of exact, do the interfix feedback on result, in order to appease the need of fact product.This project mainly completed following several aspects research work:First, outlined the content-based on image retrieval technology research situation at present and introduced the system involves to some related theory knowledge in detail.Second, bases the character of tile surface picture, choose idiographic method to completed content-based image retrieval, and stapled picture to grade according to texture in order to optimize retrieval.Finally, using c# language in Visual Studio. net 2003 which developed by Microsoft Corporation combine the sql server 2000 database and the object-oriented programming(OOP) method to program, then completed the fact system.The system mainly include following several functions: picture pretreatment; picture charater extraction and save in database; picture classes manage; picture manage; user manage; picture browse; picture retrieval; retrieval result feedback;The experimental results had indicating the feasibility and accruacy of used scheme for this system, has very great practical value.更多还原
