摘要在科技发展飞速的信息时代，我们都知道，图片和视频已经成为我们获取信息的一个很重要的渠道和方法，我们人类视觉系统处理能力有限，那么大量的图像数据给高效智能信息处理带来了很大的挑战。在我们看视频和看图像的时候，我们并不会也没有足够的精力去关注所有的部分，我们关心的内容通常只是一小部分而已。因此，我们很有必要直接检测出它们，便于高效的处理。但是显著性检测本身是一个非常复杂的问题，虽然研究者们已经取得了很多成果，但是要达到人类视觉系统的智能处理效果还必须有更加深入的研究。81767

      本论文的主要研究内容如下：

      第一部分主要讨论了视觉显著性的背景目的意义，介绍人类视觉系统的基本概念和基本原理，同时介绍几种模型如SR,SCSP等等。回顾了认知心理学的相关理论，讨论了视觉显著性和图像内容之间的对应关系。 

      第二部分集中研究了面向图像数据的视觉显著性检测的几种算法，并进行对比试验来比较各个算法之间的优点缺点和检测区分度。同时介绍演示软件MATLAB gui来直观展示各个算法的运行结果。

      论文的最后总结了本文的算法对显著性区域检测方面的工作成果，并对未来的工作方向进行了展望。

ABSTRACT    In the rapid development of science and technology information age,We all know that pictures and videos have become a very important channel and method for getting information，Our human vision system has limited processing power,Then a large number of image data to the efficient intelligent information processing has brought a great challenge。When we look at the video and look at the image, we do not have enough energy to focus on all the ，We are concerned about the content is usually only a small part of it。Therefore, we need to directly detect them, easy to deal with efficient。But the significance test itself is a very complicated problem, although the researchers have made a lot of results, but to achieve the human visual system intelligent processing effect must also have more in-depth study。

     The main contents of this thesis are as follows：

     The first part mainly discusses the background significance of visual significance, introduces the basic concepts and basic principles of human visual system, and introduces several models such as SR, SCSP, etc。The theory of cognitive psychology is reviewed, and the correspondence between visual significance and image content is discussed。

     The second part focuses on several algorithms for visual significance detection of image data, and compares experiments to compare the advantages and disadvantages of each algorithm and to distinguish the degree of detection。 At the same time introduce the demo software MATLAB gui to visualize the results of the operation of each algorithm 

     At the end of this paper, the paper summarizes the results of this paper on the work of significant regional testing, and prospects the future work direction
