Based on the multi-scale and multi-orientation characteristics of Steerable Pyramid,a novel color fusion method of visible and IR images for observation is proposed.After Steerable Pyramid decomposition,the fusion method is realized in YUV color space according to the human perception of luminance and chrominance.In luminance channel Y,the local energy and matching measure are utilized to reserve the salient information and complementary information from visible and IR images.In chrominance channel U and V,...
