基于肤色的HSV彩色模型下的人脸检测摘要本文研究的是利用人脸肤色色相的特性，即每一种人种皮肤彩色分布在一个较窄的频带上，通过对该人种的人脸皮肤建立模型，进行训练，就能够得到肤色分布的统计。考虑到一般所用的RGB彩色模型对光线的亮暗程度比较敏感，而在HSV彩色模型中，色相H分量表示了图像的彩色信息，受到光线变化的影响缓慢。所以，本文采用的是在HSV彩色模型下建立肤色模型，并对其进行训练，从而用训练后的模型对图像进行人脸检测。本文研究的主要目标是了解人脸检测的过程。同时，在实验过程中，进一步了解RGB彩色模型和HSV彩色模型的区别，了解在HSV彩色模型下人脸的肤色特性，了解如何建立皮肤模型进行训练，从而对图像的皮肤区域进行划分，进一步熟悉在MATLAB下的数字图像处理方面研究和实现。关键字：RGB彩色模型，HSV彩色模型，人脸检测，色相，肤色模型，MATLAB论文类型：应用性研究AbstractThispaperistostudythathowtousetheskincolorcharacteristicofhumanface(It’ssaidthatthefaceskincolorofeachkindofracedistributesinanarrowerfrequencyband.)toestablishmodelofhumanfaceskin,tocarryonthetrainingandtoobtainthestatisticsofthefaceskincolor.ConsideringRGBModelSpaceofColorisquitesensitivetothelightdegree,thechosenmodel,HSVModelSpaceofColor,isslowchangedbythelightforthecolorinformationjustexpressintheHuecomponent.Therefore,thefaceskincolormodelisestablishedundertheHSVModelSpaceofColorinthispaper.Aftertrainingthemodel,itcanexaminethefaceareainonepicture.Theessentialgoalofthispaperistounderstandtheprocessofhumanfacedetection.Asthesametime,intheexperimentalprocess,wecanfurtherunderstandthedifferencebetweentheRGBModelSpaceofColorandtheHSVModelSpaceofColor,realizethetheskincolorcharacteristicunderthetheskincolorcharacteristic,andknowhowtoestablishthefaceskinmodelandtrainitandfindouttheskinarea.What’smore,wewillbefurtherfamiliarwithMATLAB.Keywords:RGBModelSpaceofColor,HSVModelSpaceofColor,HumanFaceDetection,Hue,ModelofSkinColor,MATLABTypeofThesis:ApplicationResearch目录第一章绪论......................................................................1§1.1人脸检测的意义.........................................................1§1.2人脸检测研究现状.......................................................1§1.3本文工作...............................................................2第二章图像的彩色模型............................................................2§2.1图像的彩色模型简介.....................................................2§2.2RGB彩色模型............................................................2§2.2.1RGB彩色模型介绍..................................................2§2.2.2RGB彩色模型运用..................................................3§2.3HSV彩色模型............................................................3§2.3.1HSV彩色模型介绍..................................................3§2.3.2HSV彩色模型运用..................................................4第三章基于肤色的HSV彩色模型下的人脸检测.........................................4§3.1原理...................................................................4§3.1.1人脸皮肤模型的建立...............................................4§3.1.2人脸皮肤模型的训练...............................................5§3.2人脸检测...............................................................5第四章实验结果..................................................................6§4.1实验的结果.............................................................6§4.1.110幅人脸图像训练后进行检测的结...
