Multispectral fusion for synthetic aperture radar (SAR)‎ image based framelet transform

Abstract EN

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.
