Infrared and Vsible Image Fusion Method Based on Wavelet Transform

According to the feature of infrared and visible image, a method of image fusion based on wavelet transform is proposed in this paper. Firstly, we make wavelet transform for the infrared and visible image after Preprocessing and registration, so we get the different frequency wavelet coefficients of source images, then we separately do image fusion for different frequency domain after decomposition according to the rules: The low frequency wavelet coefficients are weighted and on high frequency wavelet coefficient we select large. Meanwhile we compare it with Space domain fusion algorithm according to the rules : The pixel are weighted and selected large. The simulation experiment result shows that using wavelet second fusion method has a good effect on the infrared and visible image fusion.
