摘要
本文介绍了一种用于弱环境辐射下红外中、短波双波段的红外图像融合方法。该方法先采用单尺度 Retinex(Single Scale Retinex,SSR)方法处理短波图像,分别对处理后的短波图像和 中波图像采用均值滤波和双边滤波得到细节层和背景层,再利用基于 Spectral Residual(SR)显著性和引导滤波的权重映射,对短波图像和中波图像的细节层和背景层进行加权融合,得到融合图 像。经过实验仿真,并与基于小波、拉普拉斯金字塔的多种算法做了比较,该方法在各场景下的主观与客观评价均表现良好。
Abstract
This study introduces a method of infrared image fusion for the infrared medium- and short-wave dual band. This method uses the single scale retinex(SSR) method for processing the short-wave image. Following this, the short-wave and medium-wave images are processed to obtain the details and background layers by average filtering and bilateral filtering, respectively. Using the weight map based on spectral residual significant and guided filter, the background and details layers of the short-wave and medium-wave images are fused to obtain the final fused image. From the results of the experimental simulation and a comparison with various fusion algorithms based on wavelet and the Laplacian pyramid, the method proposed in this work is observed to be simple and performs well in most scenarios.
