摘要
目的:图像挖掘技术作为图像处理的一个分支,是一门正在受到强烈关注的学科。随着图像获取和存储技术的发展,人们每天都可以获取许多有用的图像信息,但缺乏有效的分析技术分析这些数据,因此如何获取包含许多有用的信息图像数据,并充分利用这些图像数据,是目前图像挖掘技术所讨论的热点。本文就对图像挖掘的研究和应用现状进行了深入研究和分析。方法:通过阐述图像挖掘的概念、主要框架、底层图像挖掘和高层图像挖掘的主要技术,探讨了图像挖掘技术在生物医药和DNA分析中、医学影像数据分析中及法医学中的应用。结果:图像挖掘技术是一种有效分析、获取图像中所隐含的有用信息、图像数据之间的关系和其他隐含的模式的技术,而且,随着工程学和医学学科的交互渗透,图像挖掘技术也开始应用于医学领域中。结论:本文总结了目前比较常用的图像挖掘技术,同时结合我们在该领域所做的工作,对涉及的技术进行了阐述,并指出今后在医学应用中的研究方向。
Objective: As a branch of image processing, image mining is a subject for great concern. With the development of image acquisition and storage, human can gain a lot of useful image information, but lack of effective analytic technique, so it is a focus of image mining that how to obtain useful image information and make full use of image information. So this paper gives an overview of the research and applications of image mining. Method: Firstly, it presents the concept and primary frame of image mining and the major techniques of lower layer image mining and higher layer image mining. Then, it discusses some applications in the biomedical, DNA analysis, data analysis of medical imaging and forensic medicine and so on. Result: Im- age mining is that the technique which can mine to discover new and valuable knowledge from vast collection of image. Con- elusion: This article expounds the related technologies about image mining by our study of the image mining areas integrating the usual methods of the methods. Then, it identifies some applications in medicine and future research directions of image mining.
