摘要：
Multiwavelet transform is a new development to the wavelet theory. It can offer orthogonality, symmetry, and short support simultaneously, and can offer a more precise way for image analysis than wavelet multi-resolution. A now remote-sensing image fusion method based on intensity-hue-saturation transform(IHST) and Mulliwavelet Transform(MWT) is presented to fusion a multi-spectral image and a panchromatic image. Firstly, the multi-spectral image is transformed with IHST; Secondly, the panchromatic image and I component of the multi-spectral image are merged with MWT-based fusion method, and I component is replaced with the merged data; finally, the fused image is obtained by inverse IHST. Comparing with other methods, the new method can enhance spatial detail information of remote-sensing images largely and provide more spatial information at the same time.
