基于目标提取与滚动引导滤波的图像融合OA
Image Fusion Based on Target Extraction and Rolling Guided Filter
针对红外与可见光图像融合算法中出现的红外目标不突出,融合图像整体对比度低等问题,本文提出了一种基于目标提取与滚动引导滤波(RGF)的红外与可见光图像融合算法.首先,采用基于RGF 的对比度增强算法对可见光图像进行预处理,同时利用迭代引导红外图像块张量模型(IGPT)提取红外图像的显著性目标.然后,使用 RGF 对红外图像与增强后的可见光图像进行多尺度分解,得到各自的基础层和细节层.利用提取到的红外目标结合熵值比较法指导基础层融合;同时将区域能量和修正的拉普拉斯能量和用于构建权重矩阵,采用绝对值取大方法指导细节层融合.最后,通过图像重构得到最终融合结果.实验结果表明,本文算法可保留突出的红外目标、丰富的纹理细节信息,且其信息熵、标准差、互信息量、视觉感知度量4 种质量指标对比ADF、FDPE、LatLRR、VSM-WLS、SeAFusion、U2Fusion等算法均存在优势.
To solve problems associated with infrared and visible light image fusion algorithms,such as the fact that the infrared target is not prominent and the overall contrast of the fused image is low,this study investigated an infrared and visible light image fusion algorithm based on target extraction and rolling-guided filtering(RGF).First,the RGF-based contrast enhancement algorithm was used to preprocess the visible light image,and the iterative guided infrared patch tensor model(IGPT)was used to extract the salient targets from the infrared image.Then,the RGF was used to perform multiscale decomposition of the infrared and enhanced visible light images to obtain their respective base and detail layers.The extracted infrared target was used,along with the entropy value comparison method,to guide the base layer fusion;at the same time,the regional energy and modified Laplacian energy were used to construct a weight matrix,and the absolute value method was used to guide the detail layer fusion.The final fusion result was obtained through image reconstruction.Experimental results show that the algorithm developed in this study could not only effectively preserve prominent infrared target features and rich texture detail information,but also demonstrate clear comprehensive advantages over existing methods such as ADF,FDPE,LatLRR,VSM-WLS,SeAFusion,and U2Fusion in terms of four quality evaluation metrics:information entropy,standard deviation,mutual information,and visual perception measurement.
