摘 要

基于一系列的问题20世纪90年代初期,基于内容的图象检索技术开始兴起。这种图象检索系统是将自动提取得到的每幅图象视觉特征作为索引,然后根据用户提交的一幅或多幅例子图象来查找在视觉特征上相似的图象。利用对图片的检索便能加以避免。敏感图像属于图像数据是一段二进制的数据流。利用不良图片的相似特征便可以使它们无处藏身。大大的增加了搜索的范围。减小了通过人为因素而隐藏的敏感图片。对净化网络空间有着积极的意义。在本论文中,将多媒体图像处理的方法和原理应用到图像检索的过程中,构建了图像检索的基本平台。在具体制作中,使用了C++语言并且结合灰度直方图等一系列的特征算法,初步实现了基于图像内容的检索。

2 ABSTRACT

Based on the early 1990s, a series of questions, content-based image

retrievaltechnology began to rise. This image retrieval system is the automatic

extractioneach piece of image visual features as the index, then the user submits

one ormultiple examples of images to find similar images in the visual features.

Use of the image retrieval will be able to be avoided. Sensitive images belong to

the image data for some binary data stream. The use of indecent images of

similar characteristics can be so that they can not hide. Greatly increase the

scope of thesearch. Reduce the human factors and hide sensitive pictures. Has a

positive meaning to purify cyberspace. In this dissertation, the image processing

principles and methods are applied to the retrieval process, and a basic platform

for image retrieval has been built. The program was written in C++ language

and using histogram algorithm, preliminarily achieved the content-based image

retrieval.
