图书馆藏书光学特征的高效检索技术研究

Research on efficient retrieval of optical characteristics of books in the library

为了提高图书馆藏书的检索效率,采用光学特征图像分析方法进行图书馆藏书检索,能克服图书文字特征的共像性的影响,提高检索的准确性。提出一种基于激光光学成像扫描和特征提取的图书馆藏书高效检索技术,采用激光横向扫描技术进行图书馆藏书的封面和封底扫描,对扫描的藏书激光图像进行文字和图像区域分割,在激光透射空间中对采集的图书馆藏书光学图像进行像素分解和特征分离,提取光学图像的灰度值边缘特征,结合图像的语义特征提取方法进行图像融合处理,实现图书馆藏书光学特征提取,以提取的特征量为检索依据,进行藏书检索。仿真结果表明,采用该方法进行图书光藏书图像检索的查准率较高,检索时间较短,提高了检索效率。

In order to improve the retrieval efficiency of the library collection, the optical characteristics of the image analysis method for library retrieval, text books can overcome the influence of the characteristics of common image, improve the retrieval accuracy. A laser scanning imaging and feature extraction of the library based on efficient retrieval technology, the cover and the back cover of the library collection by scanning transverse laser scanning technology, laser image scanning for collection of text and image segmentation, the laser transmission space on the acquisition of the library of optical image pixel decomposition and feature extraction of gray value, optical image edge features, combined with the semantic feature of the image extraction method of image fusion, extract the parameters of the library the optical characteristics, feature extraction is the basis of search, retrieval of books. The simulation results show that the recovery the book collection of light image retrieval precision by using this method, the retrieval time is short, the retrieval efficiency is improved.
