Carries on the wavelet transformation with the Daubechies orthogonal wavelet base to the FMI image, withdraws its crack information.

δ-sequence approach to two-point boundary value problem using Daubechies wavelets;

Delta-sequence approach to solving PDE based on Daubechies wavelets;

Detection of the fundamental frequency based on Daubechies wavelet transform;

A new finite element space is studied, in which the scaling functions of Daubechies wavelets are considered as the interpolation basis funcitions, then the wavelet finite element (WFE) is constructed.

Both the Daubechies wavelets and Symlets wavelets which are widely applied in engineering are not symmetric.

In order to demonstrate the analysis error of Daubechies wavelet in signal processing, different compact support Daubechies wavelets were u.

B-spline wavelet is symmetric and anti-symmetric, its filter has characteristics of linear phase or generalized linear phase, so it can prevent distortion, Emulation shows that semi-orthogonal wavelet packet is more effective than Daubechies wavelet packet to decompose and re.
