Abstract
In this paper, the authors investigate the detailed metrological characteristics of the Dual tree Complex wavelet transform (DT-CWT). The results show that the DT-CWT not only is a finite impulse response, perfect reconstruction filter, but also has very good phase property with zero phase shift, and has a very near brick wall property, which means that by using DT-CWT filtering, the filtering result has no aliasing and can separate different frequency components more precisely. Numerical experiments and practical surface data analysis show these remarkable properties.
