A little introduction to wavelets
Guy P. Nason · 1999
Wavelets have become a popular and useful tool for the investigation and analysis of many kinds of problem. It is difficult to pin down a unique origin for wavelet theory. Many fields provided the seeds from which wavelet theory grew. These include signal processing, physics and mathematics. The range of applications that wavelets are being applied to is large and growing. This paper reviews briefly the principle of wavelets including mother wavelets and fast transforms. (6 pages)
