Information technology improving the spatial fragmentation of digital satellite images based on ica- and wavelet transform

The paper presents information technology that improves the spatial separation of multichannel images. The results show that the proposed method can have a better trade-off between spectral and spatial information. Moreover, compared with ICA fusion method, it can not only improve the spatial resolution of fused image, but also eliminate the drawback of spectral distortion of ICA fusion method in local regions.
