Abstract-The technique of fusing a panchromatic (Pan) SAR image that has a highspatial
and low-spectral resolution with multispectral (MS) SAR images that have a
low-spatial and high spectral resolution is very useful in many remote sensing
applications that require both high-spatial and high-spectral resolution. In this paper,
method for fusion SAR image is proposed based on framelet transform and new
selection rule. The framelet transform is nearly shift-invariant with desired properties,
short support, and symmetry. In the selection rule of proposed method, max rule is
replaced with new relation depending on input SAR image. The proposed method is
compared with other method such as HIS, PCA and wavelet methods. A quality of fused
image is calculated based on the combination entropy, the correlation coefficient and
the peak signal to noise ratio. It is showed from simulation result the quality measured
for proposed method can indicate the information content of the fused image is higher
compared to the information content of the input panchromatic and multispectral
images, also its noticed the proposed method provides richer information comparing
with other methods.
