图像增强算法研究摘要图像增强是计算机的重要术语,是将之前非常含糊的图像转变清楚或凸显部分特征,弱化不需要的特征,进而改变图像质量、增加信息量,强化图像判读以及辨别效果等,通过众多操纵来改变图像,可从图像中选取部分信息或改变部分信息。图像增强就是此类处理的预处理时期,就是图像处理的关键部分。图像增强是大众沟通以及得到信息的重要方式,人类利用眼,耳,鼻等得到信息,感悟信息且了解以及改变世界。根据分析,大众得到的信息中,大概百分之八十是通过图像,利用以眼睛为入口的视觉体系得到的。因此,图像就是大众最关键,最普遍的信息源,所以,图像处理应用行业就开始进入到大众工作以及生活中。图像处理科技伴随计算机科技的进步而得到明显的发展,进而转变成关键的科技领域,此科技逐渐进入到大众生活以及国家生产的众多部分,且得到普遍的使用。换句话说,图片表示客体或主体的写照或仿照,图像就是一二维或三维景物表现在大众内心深处的印象,是灵动的图形化的形色。然而,上述灵动的,形象化的信息图像并不能被计算机所认可,因此需要将其转变成数字图像,才可以进行计算机处理。关键词:图像增强,直方图均衡化,灰度变换ABSTRACTComputerimageenhancementisatermthatisnotclearfromtheimagebecameclearer,oremphasizecertainfeatures,inhibitingnotinterestedinfeatures,whichimprovetheimagequality,richininformation,enhancedimageinterpretationandrecognitionwithaseriesofactionstoimproveimages,certaininformationcanbeextractedfromanimageormodifycertaininformation.Imageenhancementinthepre-processingstageofimageprocessing,isanimportantpartofimageprocessing.Thereisalsoafeatureofimageenhancementisthehumangetsoneofthemostimportantsourceofinformationandexchangeofhumaneyes,ears,nose,bodyreceivesinformation,sensoryinformationandthustounderstandandtransformtheworld.Accordingtostatistics,intheinformationobtainedbythehuman,some75%isintheformofimages,obtainedthroughtheeyetotheentranceoftheVisualsystem.Inotherwords,theimageisthemostimportant,themostdirectsourceofinformation,sotheimageprocessingapplicationrelatestopeople'slifeandwork.Withthematuringofcomputerimageprocessingtechnologyhasrapidlydevelopedintoanimportantareaoftechnology,imageenhancementtechnologyhasbeengraduallyinvolvinghumanlifeandallaspectsofproductionandhasbeenwidelyused.Simplyput,representativeofanimageisaphotoofanotherobjectorobjectsorsimulation,theimageiseitheroneortwodimensionalorthreedimensionalscenesrenderedinthehumanimageintheeyesof,isavividdescriptionofthegraphical.However,thislively,informationvisualizationimagesarenotdirectlyacceptedbythecomputer,itmustbeconvertedintodigitalimagescanbeprocessedbycomputer,whichisdecidedbythecomputerworks.KeyWords:Imageenhancement,histogramequalization,gray-scaletransformation目录第1章绪论.................................................................................................31.1研究背景与研究意义..........................................................................................31.1.1研究背景....................................................................................................31.1.2研究意义....................................................................................................31.2应用概况..............................................................................................................41.3章节安排..............................................................................................................6第2章图像增强的基本方法.....................................................................72.1...
