Choose a Wavelet - MATLAB & Simulink
If a wavelet is orthogonal, the wavelet transform preserves energy. Except for the Haar wavelet, no orthogonal wavelet with compact support is symmetric. The associated filter has nonlinear phase. Vanishing Moments. A wavelet with N vanishing moments is orthogonal to polynomials of degree N−1....
Haar Transform
This capability is also the main advantage of wavelet transform over other orthogonal transforms. A Haar Transform Example: The Haar transform coefficients of a -point signal can be found as The inverse transform will express the signal as the linear combination of the basis functions:...
Obtaining normalized matrix for the Haar Wavelet Transform
$\begingroup$ so the point is that you want to normalize the orthogonal matrix. Gram-Schmidt is the standard method that is taught for orthonormalizing matrices (see your favourite undergrad math textbook or wikipedia); your matrix is already orthogonal, so my question is: Why does the used algorithm matter to you? If you only change the scaling of let's say each column vector, all algorithms ......
 Multispectral Multisensor Image Fusion Using Wavelet ...
As described in [12] [13], Daubechies constructed a family of orthogonal filters that generate orthogonal wavelets having compact support. The filters used in this work were for the Haar wavelet, and the 4 coefficient (Db2) and 8 coefficient (Db4) Daubechies wavelets. 3.1 Shift invariant discrete wavelet transform (SIDWT) A major drawback of ......

Unsupervised feature extraction for time series clustering ...
2.3 Haar Wavelet Transform We use the Haar wavelet in our experiments which has the fastest transform algorithm and is the most popularly used orthogonal wavelet proposed by Haar. Note that the properties mentioned in Section 2.2 are hold for all orthogonal wavelets such as the Daubechies wavelet family....
