Question: Direct calculation of wavelet coefficients

Dear Wavelet-ers,

I have an application where I'd like to be able to perform a
wavelet transform on an image using the wavelet directly for the convolution
for analysis and synthesis. I need the transform coefficients in terms of
scale and translation rather than the usual quick decomposition with the
QMF bank form in terms of orientation and scale.
Any suggestions of the wavelet to be used would be appreciated.
I'd like the wavelet to be either orthogonal or biorthogonal, perfect
reconstruction and symmetric. I have numerous listings of the QMF bank
filters, but not the wavelet they correspond to. Can the wavelet be easily
calculated numerically from the filter coefficients?


Thanks in advance,

Jeff Paynowski
