Polarimetric image fusion algorithms based on wavelet transform and performance evaluation

Several fusion algorithms of polarimetric images based on the wavelet transform are introduced,and an approach is developed in which the multi-resolution wavelet coefficients are processed individually,the maximum of low-frequency image wavelet coefficients is adopted as the fusion low-frequency image wavelet coefficient, and the high-frequency image fusion rules are used to adjust high-frequency image wavelet coefficients. The quality of the fusion images is compared, and the features of these methods are obtained. Experimental results show that the presented algorithms can retain subtle details of an image with an excellent effect.
