Abstract:A variety of image fusion algorithms are comparatively analyzed in order to solve the apparent seam problem caused by the non-uniform lighting and by the features of the core images themselves. The multi-resolution image fusion algorithm is introduced into the core images stitching. The Laplacian pyramid structure is used in the algorithm, which decomposes the images according to the frequency, and fuses the band-pass images at each frequency respectively. Then the inverse transform is performed to restore the fusion results of the images, and ultimately the seamless stitching of core images is achieved.
