Mode Adaptive Infrared and Visible Image Fusion

To solve the problems of low contrast and high noise of fused images in low illumination and smoky environments, a mode-adaptive infrared and visible image fusion method (MAFusion) is proposed. Firstly, the infrared and visible images are input into the adaptive weighting module in the generator, and the difference between them is learned through two streams interactive learning. The different contribution proportion of the two modes to the image fusion task in different environments is obtained. Then, according to the characteristics of each modal feature, the corresponding weights of each modal feature are obtained independently, and the fusion feature is obtained by weighted fusion. Finally, to improve the learning efficiency of the model and supplement the multi-scale features of the fused image, a residual block and jump connection combination module are added to the image fusion process to improve the network performance. The fusion quality was evaluated using the TNO and KAIST datasets. The results show that the visual effect of the proposed method is good in subjective evaluation, and the performance indexes of information entropy, mutual information, and noise-based evaluation are better than those of the comparison method.
