Paper Abstract

We introduce a novel method for image fusion based on wavelet packets. Our ideas yield an approach for pan-sharpening low spatial resolution multispectral images with high spatial resolution panchromatic images. Two distinct algorithms for fusing are investigated, based on which wavelet packet coefficients are mixed. We evaluate our algorithm on images acquired from Landsat 7 ETM+, showing an improvement over results achieved through more basic wavelet algorithms. We also propose the use of spectral concentration during the wavelet packet pan-sharpening process to reduce the dimensionality of the data.
