The Study of Image Fusion Method Based on Wavelet-Packet Transform

Based on the IHS transform and wavelet packet transform, a scheme of remote-sensing images fusion aiming at protecting image's spectral characteristics is made in this paper. This scheme makes best use of the information in remote-sensing images to be fused and prevents the loss of image information. Through the experiment using SAR image and TM image, all the spectral characteristics, the textural feature and the spatial quality of image have been improved.
