Question: Image proc. with analytic wavelets

Hello,

I'm trying to find a way to perform the 2-D wavelet transform on images
using an analytic wavelet function (i.e. Mexican hat, Meyer, etc..) rather
than using the Daubechies coefficient matrix (which is commonly done).
Given such a wavelet (orthonormal or not), which is one dimensional, how
would I go about such a procedure on, say, a 512x512 grayscale image???
Do I still follow the same multiresolution decomposition as prescribed by
S. Mallat? The wavelets that I work with a mostly nonorthogonal - thus
require a dual in order to perform an inverse transformation. Any help
on this matter would be greatly appreciated.
