Abstract
We propose a dual-band fusion method using multiscale visual saliency extraction based on spatial weight matrix. There are two main contributions in this paper. The first major contribution is to use the local window based on the gray distance of the spatial weight for saliency extraction. Second, to emphasize those potential targets and details with different sizes from source images, we based on the saliency extraction method of multi-window and fusion of different scales to achieve the preservation of more information. The proposed method is mainly divided into four steps. First, we use a spatial weight matrix of different window sizes to enhance targets of different sizes in the image. Then, through the different processing of each enhanced image to get detailed images, we use a special method to fuse the obtained details of each scale. Then, reconstruct the results obtained at each scale. Finally, we have the exact weight index selection to get better fusion results. This method solves the problem of improper weight selection and the result deteriorates. Through comparison and verification, our results retain more detailed information from the original images.
