• Add HPF data to each band of low- resolution data. The HPF image is weighted relative to the
global standard deviation of each low- resolution band.
• The fused image is stretched to match the mean and standard deviation of the low-
resolution image.
Therefore, the parameters that need to be considered for HPF fusion are value R, kernel size, and
the weight factor, which determines the crispness of the fused image.
8.3.2.2 Wavelet Fusion
In wavelet transform, the key element is the selection of the base waveform to be used. The base
waveform is called the mother wavelet, which is used to represent the image. The input signal
(image) is broken down into successively smaller multiples ...
