WebDec 1, 2008 · In this paper, we study semi-orthogonal frame wavelets and Parseval frame wavelets (PFWs) in L 2 (R d) with matrix dilations of form (Df) (x) = 2 f (Ax), where A is an arbitrary expanding d × d matrix with integer coefficients, such that det A = 2.Firstly, we obtain a necessary and sufficient condition for a frame wavelet to be a semi … A wavelet is a wave-like oscillation with an amplitude that begins at zero, increases or decreases, and then returns to zero one or more times. Wavelets are termed a "brief oscillation". A taxonomy of wavelets has been established, based on the number and direction of its pulses. Wavelets are imbued with specific properties that make them useful for signal processing.
