Abstract

We present two- and three-dimensional nonseparable wavelets. They are obtained from discrete-time bases by iterating filter banks. We consider three sampling lattices: quincunx, separable by two in two dimension, and FCO. The design methods are based either on cascade structures or on the McClellan transformation in the quincunx case. We give a few design exemples. In particular, the first example of an orthogonal 2-D wavelets basis with symetries is constructed.
