On Discrete Multiresolution Analytic Signals

(Paper (pdf) / Paper (ps))
We extend the concepts of discrete analytic functions to
multiresolution analytic functions using the spectral representation
of wreath product cyclic groups. Phase congruency and local energy
used in the identification of features, are extended to apply to the
multiresolution case. A key feature of the extension is the low
computation cost.
