A new hierarchical scheme for approximating the continuous wavelettransform with applications to edge detection

摘要

We propose an approximation of a continuous wavelet transformn(CWT) that is based on a hierarchical scheme, similar to the fastndiscrete wavelet transform. This approximation keeps redundancies inntime and scale. Furthermore, it preserves properties of the CWTnregarding the characterization of singularities and leads to efficientnapplications in multiscale edge detection
