Research on night vision image colorization based on the fusion of image′s character library

This paper describes a Night Vision Image Colorization based on image fusion technology.Concerning their characteristics,low-level visible and IR images are combined into a fusion image using wavelet fusion.We extract different patterns of textures to construct a library based on lots of experiments,and the color images are destined for different patterns.We segment the target image and compute the texture of different patterns.And the color transformation is achieved.The experimental results show that the algorithm can make a color night vision image more realistic and natural,helps observers to get more abundant scene information.
