#18 Question: Wavelet and irreducible invariants

Dear waveleteers,
I am a new comer in wavelet. Currently I am doing the medical image
segmentation. From literature, the Gaussian and all its partial
derivatives provides a complete representation of image structure. Some
image features which are invariant under orthogonal co-ordinate
transformations are irreducible invariants(S. Haring, A multiscale
Approach to Image Segmentation using kohonen network, 13th international
conference of information processing in medical imaging, pp. 212-224).
Mallat has derived a paticular wavelets which are the derivative of a
smoothing function. So spline wavelets are very similar to the
irreducible invariants. Is it correct?
Thanks for attention.
