Description: articles on real sequence Fast Fourier Transform algorithm Derivation Principle and Mallat algorithm analysis, discrete wavelet transform (DWT) algorithm structure, a fast discrete wavelet transform algorithm, corresponding to the given algorithm steps. From a theoretical mathematical proof, and the algorithm is applied to the static image processing, to be a good and rapid reconstruction effect, it is of great practical value. Keywords : wavelet analysis; Mallat algorithm; Fast Wavelet Image Processing Algorithms Key words : ODFD code : A preamble to a wavelet analysis of the last 10 years developed rapidly emerging disciplines and signal analysis theory, Fourier analysis is the method after a major mutation. It is localized in time domain and frequency domain of local advantages, but hig
