FLGC-Fusion GAN: An Enhanced Fusion GAN Model by Importing Fully Learnable Group Convolution

Abstract EN

The purpose of image fusion is to combine the source images of the same scene into a single composite image with more useful information and better visual effects.

Fusion GAN has made a breakthrough in this field by proposing to use the generative adversarial network to fuse images.

In some cases, considering retain infrared radiation information and gradient information at the same time, the existing fusion methods ignore the image contrast and other elements.

To this end, we propose a new end-to-end network structure based on generative adversarial networks (GANs), termed as FLGC-Fusion GAN.

In the generator, using the learnable grouping convolution can improve the efficiency of the model and save computing resources.

Therefore, we can have a better trade-off between the accuracy and speed of the model.

Besides, we take the residual dense block as the basic network building unit and use the perception characteristics of the inactive as content loss characteristics of input, achieving the effect of deep network supervision.

Experimental results on two public datasets show that the proposed method performs well in subjective visual performance and objective criteria and has obvious advantages over other current typical methods.
