“…In the infrared and visible images fusion, many methods have been proposed in the past few years, and they can be divided into six categories according to corresponding schemes, including pyramid methods [ 5 , 6 ], neural network-based methods [ 7 ], wavelet transformation based methods [ 8 ], sparse representation methods [ 9 , 10 ], salient feature methods [ 11 , 12 ], and other methods [ 13 ]. There are three main parts in these fusion methods, i.e., (i) domain transform, (ii) activity level measurement, and (iii) fusion rule design.…”
