Howtosignalprocessing
Wavelet analysis is an alternative to windowed Fourier transforms that also yields a two-dimensional plot showing strengths of variations as a function of both period (or frequency) and time.

What is wavelet method?
Wavelet method is a recently developed tool in applied mathematics. Investigation of various wavelet methods, for its capability of analyzing various dynamic phenomena through waves gained more and more attention in engineering research.
What is wavelet based signal analysis?
The basic idea of wavelet analysis is that of multi-resolution signal decomposition introduced by Mallat (i.e., the simultaneous appearance of a signal on multiple scales to study its various features) [5].
What is wavelet analysis in image processing?
Wavelets based transform are mathematical tools which are used to extract information from images [12]. A significant benefit it has over Fourier transforms is temporal resolution which signifies that it can captures both frequency and location information of the images [13].
What is Fourier and wavelet analysis?
"Fourier and Wavelet Analysis is primarily an introduction to the theory of Fourier series and Fourier transforms … . There are many sets of exercises that expand on the material in the text, each followed by a corresponding set of hints and/or answers.
