A Weighted Fusion Method for UAV Hyperspectral Image Splicing

In order to obtain a wide field of view and high spatial resolution hyperspectral image, image splicing has been widely studied. This paper proposed a weighted fusion algorithm to address the phenomenon of color inhomogeneity in the overlapping regions of two spliced images, which is caused by different light intensity or different camera angles of scanning. Different from the traditional direct average fusion methods, the proposed weighted algorithm conducted the fusion of the overlapping regions with adaptive weights change. The simulation results show that the proposed weighted average fusion algorithm can effectively eliminate the seam between two parts of the assembled image, making the transition of the fusion area more naturally [1].
