Infrared and visible image fusion based on Laplacian pyramid and generative adversarial network

Abstract

An image with infrared features and visible details is obtained by processing infrared and visible images.In this paper, a fusion method based on Laplacian pyramid and generative adversarial network is proposed to obtain high quality fusion images, termed as Laplacian-GAN.Firstly, the base and detail layers are obtained by decomposing the source images.Secondly, we utilize the Laplacian pyramid-based method to fuse these base layers to obtain more information of the base layer.Thirdly, the detail part is fused by a generative adversarial network.In addition, generative adversarial network avoids the manual design complicated fusion rules.Finally, the fused base layer and fused detail layer are reconstructed to obtain the fused image.Experimental results demonstrate that the proposed method can obtain state-ofthe-art fusion performance in both visual quality and objective assessment.In terms of visual observation, the fusion image obtained by Laplacian-GAN algorithm in this paper is clearer in detail.At the same time, in the six metrics of MI, AG, EI, MS_SSIM, abf Q and SCD, the algorithm presented in this paper has improved by 0.62%, 7.10%, 14.53%, 12.18%, 34.33% and 12.23%, respectively, compared with the best of the other three algorithms.
