Construction method of three-channel non-separable symmetric wavelets with arbitrary dilation matrices and its applications in multispectral image fusion.

Image fusion method based on separable discrete wavelet transform has block effect and the spatial resolution is lower in the fusion result images. The design method of filter bank relies on the form of the dilation matrices in the image fusion method based on three-channel non-separable wavelet. To resolve these problems, a new construction method of the filter banks based on three-channel non-se...
