Abstract

To effectively explore image content for image fusion and generate a full end-to-end image fusion pipeline, a parameter adaption algorithm based on gradient transfer and total variation (TV) minimization is proposed, and the fusion problem is transformed into a human visual system guided TV minimization problem, where the data fidelity term maintains the structure edge features of the image, and the regularization term preserves the gradient variation texture detail information. Then, the fusion problem is cast into the optimization of minimum energy functional model. To facilitate choice of regularization parameter, a modified fixed-point iterative method is employed to solve the optimization. Extensive experiments show that this model can obtain both rich detail and spectral information; adjusting the parameters of the proposed adaptive selection strategy can effectively improve the fusion effect while making the image fusion process work as an end-to-end pipeline. Compared to eight state-of-the-art fusion methods, the experimental results demonstrate the effectiveness of the proposed method.
