WebFourier series isn't the only way to decompose a function as a sum of pieces. Haar wavelets allow us to separate out the high-frequency and low-frequency par... The Haar transform is derived from the Haar matrix. An example of a 4×4 Haar transformation matrix is shown below. H 4 = 1 2 [ 1 1 1 1 1 1 − 1 − 1 2 − 2 0 0 0 0 2 − 2 ] {\displaystyle H_{4}={\frac {1}{2}}{\begin{bmatrix}1&1&1&1\\1&1&-1&-1\\{\sqrt {2}}&-{\sqrt {2}}&0&0\\0&0&{\sqrt {2}}&-{\sqrt {2}}\end{bmatrix}}} See more In mathematics, the Haar wavelet is a sequence of rescaled "square-shaped" functions which together form a wavelet family or basis. Wavelet analysis is similar to Fourier analysis in that it allows a target function over an … See more For every pair n, k of integers in $${\displaystyle \mathbb {Z} }$$, the Haar function ψn,k is defined on the real line $${\displaystyle \mathbb {R} }$$ by the formula See more The 2×2 Haar matrix that is associated with the Haar wavelet is $${\displaystyle H_{2}={\begin{bmatrix}1&1\\1&-1\end{bmatrix}}.}$$ Using the discrete wavelet transform, one can transform any … See more • "Haar system", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Free Haar wavelet filtering implementation and interactive demo See more In this section, the discussion is restricted to the unit interval [0, 1] and to the Haar functions that are supported on [0, 1].
