Refer to the function nd.dwt and the section "Non-Decimated Wavelets" in the S+WAVELETS User's Manual for more details about the atrous function. BUGS: Subscripting is not fully supported. Cannot reconstruct from [ [ . Signal x is assumed to be periodic.
Fast Fourier and wavelet transform based image fusion methods retain better spectral characteristics but represent poor spatial details in fused images. Objective of this paper is to develop a method, which retains better characteristics of both spatial and spectral qualities of source images.

Image Contrast Enhancement using Atrous Wavelet Transforn and Singular Value Decomposition(SVD) Satellite images are used in many areas of remote sensing. The quality of the displayed is influenced by many factor .One of the most important factor is contrast which is created by the difference in luminance reflected from two adjacent surfaces.
A systematic framework for the discrete wavelet transform is provided, and conditions are derived under which it computes the continuous wavelet transform exactly. Suitable filter constraints for finite energy and boundedness of the discrete transform are also derived.
In this paper, a new satellite image contrast enhancement technique based on s Atrous wavelet transform and singular value decomposition (SVD) has been proposed. To obtain shift invariant discrete wavelet transform decomposition for images, we introduced the discrete wavelet transform known a "A trous" algorithm to decompose the image into wavelet planes which is computed as the difference
