Advanced F-Transform-Based Image Fusion

Algorithm 1

for all input images do

 Compute the inverse F-transform

 Compute the first absolute difference between the original image and the

inverse F-transform of it

 Compute the second absolute difference between the first one and its inverse

F-transform and set them as weights of pixels

end for

for all pixels in an image do

 Compute the value of sow—the sum of weights over all input images

 for all input images do

  Compute the value of wr—the ratio between the weight of a current

pixel and sow

 end for

 Compute the fused value of a pixel in the resulting image as a weighted

(by wr) sum of input image values
