VISUAL AND INFRARED NIGHT IMAGE FUSION ALGORITHM BASED ON COLOR TRANSFER
An image fusion method is presented based on natural daytime colors for visual and infrared night image fusion.The dual-tree complex wavelet transform (DT-CWT) is applied in gray image fusion processing because of its properties:shift invariance,directional selectivity,in order to obtaining exact position and clear image presentation.The different fusion rule is used to aim at high and low frequency components.The weighted average method is employed to low frequency part,and the high frequency parts are of selection greater local energy.The color transfer technology is validated based on Lαβ space.The appropriate dynamic range of gray image in Lαβ space is proposed,and the reason of oversaturated colors is analyzed.The experiment results indicate that the proposed algorithm can achieve three requirements:detectability of the target,clear details and natural colors.
