Summary: We construct a new type of Haar wavelets, called \(\tau\)-wavelets of Haar, using the arithmetics of the solutions \(\tau=\frac 12 (1+\sqrt{5})\) and \(\sigma=\frac 12 (1-\sqrt{5})\) of the algebraic equation \(x^2=x+1\).

The Haar wavelets operational matrix of integration
International Journal of Systems Science, 1996The Haar wavelets operational matrix of integration P is derived, which is similar to those previously derived for other types of orthogonal functions such as Walsh, block-pulse, Laguerre, Legendre and Chebyshev. A general procedure of forming this matrix P is summarized.

Int-Haar: Improving Precision of the Haar Interval Wavelet Extension
2013 2nd Workshop-School on Theoretical Computer Science, 2013This work describes the interval extension of the Haar Wavelet Transform (HWT), implemented with C-XSC, being the first step on the development of the Int-DWTs library, which will provide interval results for several Discrete Wavelet Transforms (DWTs).

Application of Haar Wavelets on Medical Images
Journal of Electronic Commerce in Organizations, 2015Recently, the information processing approaches are increased. These methods can be used for several purposes: compressing, restoring, and information encoding. The raw data are less presented and are gradually replaced by others formats in terms of space or speed of access.

Nonuniform Compression in Databases with Haar Wavelet
2007 Data Compression Conference (DCC'07), 2007Data synopsis is a lossy compressed representation of data stored into databases that helps the query optimizer to speed up the query process, e.g. time to retrieve the data from the database. An efficient data synopsis must provide accurate information about the distribution of data to the query optimizer at any point in time.

Selective Crypting with Haar-Wavelets
2000The coefficients of a wavelet—decomposition form into different levels according to the size of the described details. This can be utilized to crypt only a part of the given data while keeping the rest unchanged so that critical information is filtered out.
