Abstract:
Among the various image fusion methods, wavelet-based method provides superior radiometric quality. However, fusion processing is not simple or flexible because many low- and high-frequency subbands are often produced in the wavelet domain. To address this issue, a novel dual-tree complex wavelet fusion method that uses wavelet domain zero-padding (WZP) is proposed. Experiments conducted using high-resolution satellite images demonstrated promising results in terms of computation cost.
