Ma She · Dianzi xuebao · 2001
Multiscale edges of a signal can be detected by using extrema or zero crosings of dyadic wavelet transform.A reconstruction algorithm by cubic spline function interpolation,which is used to recover a signal from its dyadic wavelet transform extrema is proposed in this paper.Numerous experiments demonstrate its satisfying properties.Compared with previous algorithms it is simpler,more straightforward and faster.
