Content-based Tile Image Retrieval System Based On Web

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.
