第45卷第21期2023年11月舰船科学技术SHIPSCIENCEANDTECHNOLOGYVol.45,No.21Nov.,2023舰船红外目标图像视觉传达增强张雯靖（郑州科技学院，河南郑州450064）摘要：针对舰船红外图像获取性难和敏感性问题，提出一种舰船红外目标图像视觉传达增强方法，提升舰船红外目标图象质量。采用改进的中值滤波预处理舰船红外图像，有效去除舰船红外图像中海浪的冲击噪声；通过Renyi熵方法将处理后的舰船红外图像二值化分割为前景域和背景域，以区分舰船目标和背景；通过改进的平台直方图均衡方法剔除舰船目标和背景红外图像穴余的像素点，均衡分配灰度值，实现舰船目标和背景增强；经改进的Canny对增强后舰船目标和背景图像边缘加权融合，得到最终的舰船增强图像。实验结果表明，所提方法可以有效去除舰船图像噪声，提升舰船红外图像的对比度，对图像和图像边缘的信息保有量充分，大幅提高了红外图像的质量和清晰度，加大了舰船红外目标图像视觉传达增强的可行性。关键词：舰船红外图像；视觉传达增强；中值滤波；Renyi熵；平台直方图均衡；Canny算法中图分类号：TP391文章编号：1672-7649(2023)21-0201-04Visualcommunicationenhancementofshipinfraredtargetimages(ZhengzhouInstituteofScienceandTechnology,Zhengzhou450064,China)Abstract:Avisualcommunicationenhancementmethodforshipinfraredtargetimagesisproposedtoaddresstheis-suesofdifficultyandsensitivityinobtainingshipinfraredimages,inordertoimprovethequalityofshipinfraredtargetim-ages.Adoptingimprovedmedianfilteringtopreprocessshipinfraredimages,effectivelyremovingtheimpactnoiseofwavesinshipinfraredimages;ByusingtheRenyientropymethod,theprocessedshipinfraredimageisbinarizedandsegmentedintoforegroundandbackgrounddomainstodistinguishshiptargetsandbackgrounds.Byusinganimprovedplatformhisto-gramequalizationmethodtoeliminateredundantpixelpointsinshiptargetsandbackgroundinfraredimages,thegrayscalevaluesareevenlydistributedtoachieveshiptargetandbackgroundenhancement.TheimprovedCannyweightsandfusestheedgesoftheenhancedshiptargetsandbackgroundimagestoobtainthefinalshipenhancedimage.Theexperimentalresultsshowthattheproposedmethodcaneffectivelyremovenoisefromshipimages,improvethecontrastofshipinfraredimages,retainsufficient...
