Abstract: We applied an image fusion approach that uses different wavelet transforms for the forward and reconstruction transforms to efficiently compact energy for improved reconstruction. In addition, we used denoising to reduce the error induced by this approach. We found that using such an approach generally increases the Average Relative Entropy (ARE) of the fused result when compared to a conventional image fusion method.

Keywords: denoising; feature extraction; image fusion; thresholding; wavelet transforms; average relative entropy.
