1D and 2D Wavelet Packet decomposition and reconstruction Approximating wavelet and scaling functions Over seventy built-in wavelet filters and custom wavelets supported Single and double precision calculations Real and complex calculations Results compatible with Matlab Wavelet Toolbox (TM)Requirements...
1D and 2D Wavelet Packet decomposition and reconstruction 1D Continuous Wavelet Transform When multiple valid implementations are available, we have chosen to maintain consistency with |MATLAB|'s Wavelet Toolbox. PyWavelets 0.5.0 is the culmination of 1 year of work. In addition to ...
Liu et al. [24] presented an innovative hybrid system for four towns in China called WPD-PSO-BP-Adaboost, based on wavelet packet decomposition (WPD), the particle swarm algorithm (PSO) algorithm, the back propagation neural network (BPNN), and the Adaboost model. Sun and Xu [25] ...

To circumvent the problem of non-stationarity, advanced algorithms exist that analyze a signal based on their decomposition in elementary signals that are well localized (or boxed) in time and frequency4. These include the short-term Fourier transform (STFT), also known as the Gabor transform, ...
