基于内容的彩色图像过滤技术研究-光学工程专业论文.docx

摘要摘要 摘要 摘要 随着互联网技术迅速的发展，人们可以通过网络更加容易的获取各种信息，但同 时，也使得非法和不健康的信息更加容易散播。因此，如何保护和防止网络用户在上 网时不被那些有害信息所毒害，成为当前科研中一项重要课题。本文以此为背景，对 色情图像过滤的关键技术进行了研究，并在此基础上提出了图像过滤的体系结构，实 验证明基于该体系结构的过滤器可以有效地过滤色情图像。 我们在国内外相关研究的基础上，依据图像过滤器的通用模型，在肤色、纹理和 分布模型的表述上提出了自己的方法，并通过分析特征之间的相互关系，找到了两个 辅助的分类依据。在分类决策算法上，我们使用了我们在图像检索研究中用过的加权 求和算法进行最终的决策。此外，本项研究的主要工作还包括构造了一个6000幅图 像的图库，并利用Visual Basic将算法集成在一起，做成了一个图像过滤软件。通过 任意抽取的800幅图像对该软件进行检测，我们的平均正确率可达95．75％，平均误判 率为19．75％。从检测结果来看，我们的过滤算法是有效的。 关键词：图像过滤，肤色特征，纹理特征，分布特征，加权求和 Abs订acCAbstract Abs订acC Abstract Due to the dramatic growth of network and multimedia technology，people can more easily get variant information by using Internet．Unfortunately，it also makes the information of illegal and harmful content much easier．So，it becomes an important topiC to protect and safeguard Internet users from these information．ThiS text proceeds regarding thiS as the background，key technique towards erotic image fiitering research，combine here the foundation up bring upped the diagram to resemble the percolation’S system construction， experiment proofed according to that fiitering of construction system can availably fiItering the erotic the diagram to resemble． We are on the foundation of the domestic and international related research． and bring upped the own method on the describing the skin—color model，veins model and distribute model based on image fiiter’S in general use model，and pass to analyze of the characteristic the elassification basiS for of correlation．find out two assistant classify—rule．On the classification make policy the ca]culate way，we used a weighted algorithm in the summation process which WO used in image retrieval to proceed final decision．In addition，the main work of thiS research still included to constructed a gallery with 6000 images，and make use of the Visual Basic to gather the calculate way together， make a image filtering software．Pass arbitrarily 800 images that are taked from the gallery to examine the software，our aver
