Abstract

Multiwavelet transform, a new notion addition to wavelet theory, offers simultaneous orthogonality, symmetry, short support, and vanishing moments, which are not possible with scalar wavelets. In this paper, a novel fusion method for Landsat Thematic Mapper (TM) and Synergetic Aperture Radar (SAR) images using multiwavelet transform is proposed. The approximation subband of the fused multiwavelet transform representation is from that of Landsat TM image, and the detail subbands are constructed by fusing those of Landsat TM and SAR images. The proposed method was compared quantitatively with intensity-hue-saturation, principal component analysis, and wavelet transform. It was found that the presented technique is clearly better than those methods in preserving both spectral and spatial information.
