Paper Abstract

The authors study large panchromatic images and ultraviolet (UV) images. The paper presents an image fusion algorithm based on wavelet transform. Because the panchromatic image contains the detail of rock surface, we select larger low frequency coefficient. At the same time, ultraviolet images contain the important information of rock edge with less detail, so we select larger high frequency coefficient, and use wavelet modulus maximum to find the localizer of UV image edge, use the localizer to enhance the fusion image using panchromatic image. Experiment results show that the fusion algorithm is satisfactory.
