Web3.23.2.1 Wavelet Basis Functions. Wavelets are a set of self-similar mathematical functions that are used to approximate more complex functions via superpositioning principles. Wavelets also allow a signal to be divided into different frequency and time components.1 Wavelets have been applied extensively in the fields of biology, chemistry ... WebWavelet analysis is one of the most efficient tools for signal and image processing. For multiresolution analysis, a mother wavelet of varying width with low and high-frequency bases is used for detecting the image discontinuities. A particular rigid mother wavelet is used to construct a filter bank for the time–frequency analysis of an image. spectrum financial services hickory nc
