基于内容的图像检索技术

Content-Based Image Retrieval Technology

随着多媒体技术的迅速发展,传统的基于关键字的信息检索技术已逐渐不能满足要求,因此,基于内容的图像检索技术成为当今的一个研究热点。介绍了基于内容图像检索系统的基本组成。综述了基于颜色、纹理、形状、语义等图像检索技术的主要方法。分析和比较了现有的各种图像检索技术的方法。讨论了相关反馈技术、检索性能的评价等CBIR研究中的关键问题。同时指出了CBIR研究中存在的问题,以及未来的发展趋势和研究方向。

With the rapid development of technology of multimedia, the traditional information retrieval techniques based on keywords are not sufficient, content - based knage retrieval（CBIR） has been an active research topic. The basic components of content - based image retrieval system are introduced. Image retrieval methods based on color, texture, shape and semantic are discussed, analyzed and compared. Same key methods such as the relevance feedback, the performance evaluation and so on are also discussed. From evaluating them,have presented the current challenges and future trends for CBIR.
