What is mother wavelet?
Wavelets are a class of a functions used to localize a given function in both space and scaling. A family of wavelets can be constructed from a function , sometimes known as a "mother wavelet," which is confined in a finite interval. "
How do I choose a mother wavelet?
Both the optimal mother wavelet and decomposition level are selected by evaluating signal-to-noise-ratio (SNR) efficiency of the denoised signals obtained by using the wavelet thresholding method.
Is haar a mother wavelet?
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 interval to be represented in terms of an orthonormal basis.
What is a mother wavelet in image processing?
Wavelet are basically produced from one single function (basis function) called mother wavelet. The wavelet function work on an idea of using a family of functions localized in both time and frequency. It represents an image as a sum of wavelet functions with different locations and scales.
