Abstract:

In order to solve the problem that existing infrared and visible light image fusion techniques often suffer from artifacts caused by insufficient contrast, spectral distortion, and high computational complexity, a fusion framework based on ResNet-50 and Laplacian filtering was proposed. ResNet-50 was used to extract shallow and deep features, followed by multi-scale feature fusion. Laplacian filtering was applied to optimize feature information, and an automatic discriminator was introduced to further improve the fusion effect. Simulation results show that, compared with comparison algorithms, the proposed method achieves an average increase of 2.71% and 2.16% in information entropy, 5.98% and 7.86% in visual information fidelity, and 12.57% and 14.63% in wavelet-based feature mutual information on the TNO and VIFB datasets, respectively, which proves its effectiveness in improving image fusion quality.

Key words: image fusion, ResNet-50, Laplacian filtering, deep learning, automatic discriminator
