基于Matlab的PS图像特效处理功能摘要MATLAB是一套集数值计算、符号计算和图形图像处理等强大功能于一体的科学计算语言。作为一个强大的科学计算平台，它几乎可以满足所有的计算需求。作为一种数值计算软件，它在数字图像处理领域有着很好的性能。MATLAB的一个主要特征是对特定区域的图像或者一个像素的处理、光照处理、色彩处理、图形的四维数据的表现，也不能取代其他软件。本文阐述了图像处理的基本原理，探讨了利用MATLAB作为色彩调整的工具，代数，几何，滤镜效果，艺术效果，失真效果和图像处理的风格。经过实际验证，MATLAB在图像处理领域也有很好的表现。关键词：Matlab；图像处理；图像特效abstractMATLABisasetofscientificnumericalcalculation,symboliccomputationandgraphicsandimageprocessingandotherfunctionsinoneofthepowerfulcomputinglanguage.Asapowerfulscientificcomputingplatform,itcanmeetalmostallcomputingneeds.Asakindofnumericalcalculationsoftware,itisinthefieldofdigitalimageprocessingisoneofthemainfeaturesof.MATLAB'sperformancegoodistheimageofaspecialareaorapixel,illuminationprocessing,colorprocessing,four-dimensionaldatagraphicsperformance,butalsocannotreplaceothersoftware.Thispaperdescribesthebasicprincipleofimageprocessing,discussestheuseofMATLABasacoloradjustmenttool,generationNumber,geometry,filtereffect,artisticeffect,distortioneffectandimageprocessingstyle.Aftertheactualverification,MATLABhasagoodperformanceinthefieldofimageprocessingKeywords:Matlab;imageprocessing;imageeffects目录摘要................................................................1abstract............................................................2目录................................................................31绪论..............................................................41.1课题研究目的................................................41.2课题研究现状及发展趋势......................................51.2.1研究现状...............................................51.2.2发展趋势...............................................52数字图像处理基础..................................................62.1图像处理目的................................................82.2图像处理研究内容............................................83用Matlab实现的特效算法...........................................93.1图像色彩和色调调整..........................................93.1.1色彩平衡...............................................93.1.2亮度处理..............................................103.1.3对比度处理............................................113.1.4灰度处理..............................................123.1.5伪彩色................................................133.1.6色彩通道处理..........................................163.1.7亮度映射..............................................163.2代数运算...................................................173.2.1加减乘除运算..........................................173.2.2求异运算.............................................183.3艺术效果...................................................193.3.1剪纸..................................................193.3.2素描.................................................194总结.............................................................20参考文献...........................................................211绪论1.1课题研究目的Photoshop简称ps，是一款图像编辑，特效处理，以及创意制作于一体的专业图像处理软件之一。众所周知，图像信息是我们从外界获取信息的来源之一，目的是为了在茫茫...
