Research on the Fusion Algorithm of Infrared and Visible Images Based on Non-subsampled Shearlet Transform
Aiming at the different features between infrared imagery and visible images
a new fusion algorithm of infrared imagery and visible image based on Non-subsampled Shearlet Transform (NSST) is proposed.Firstly the algorithm decomposes infrared and visible light image that have been registered by NSST
getting the low-frequency subband images and the scale of each direction high frequency subband images;Then the low frequency subband images use a low frequency fusion rules based on the significant figure
and combined with human visual characteristic
high frequency subband image adopt a fusion rules of improving regional contrast;Finally
get fusion image by making NSST inverse transformation for the fusion of low frequency subband image and high frequency subband images.Experimental results show that the proposed algorithm can effectively synthesize the important information of infrared and visible images
and the fusion effect is better than that of the general image fusion method based on NSCT and NSST.
