摘　　要：为改善现有融合策略对源图像信息利用不够充分的问题,利用滚动引导滤波器和各向异性扩散来提取基础层和细节层,对获取的基础层和细节层分别使用视觉显著映射和权重图构建的方法进行融合,然后添加某一权重将融合后的基础层与细节层图像融合为最终图像。基于公开数据集的多个场景进行方法实验验证。实验结果表明,相比其他方法,所提方法得到的融合结果具有更好的对比度,在保持图像像素强度均匀分布的前提下在边缘细节处保留了丰富的纹理特征,具有更好的视觉效果和融合精度,同时在平均梯度、信息熵、空间频率等指标上取得了显著的进步。To solve the problem of insufficient use of source image information by existing fusion methods,a method is proposed using rolling guided filter and anisotropic diffusion to extract the base and detail layers of an image,respectively.These layers were then fused using visual saliency mapping and weight map construction,and a certain weight was added to merge the fused layers into the final image.The proposed method was tested and verified using several scenes from an open dataset.The experimental results show that the final images obtained using the proposed method exhibit better contrast,retain richer texture features at edge details,and maintain a uniform image pixel intensity distribution;furthermore,the visual effects and fusion accuracy of the final images are better than other existing fusion methods.Moreover,significant progress has been made in indicators,such as average gradient,information entropy,and spatial frequency.
