Using the discrete wavelet frame transform to merge Landsat TM and SPOT panchromatic images

In this paper, we propose a pixel level image fusion algorithm for merging Landsat thematic mapper (TM) images and SPOT panchromatic images. The two source images are first decomposed using the discrete wavelet frame transform (DWFT), which is both aliasing free and translation invariant. Wavelet coefficients from TM’s approximation subband and SPOT’s… CONTINUE READING
