Integrating wavelet functions¶
The result of the call depends on the wavelet
argument:
for orthogonal and continuous wavelets - an integral of the wavelet function specified on an x-grid:
[int_psi, x_grid] = integrate_wavelet(wavelet, precision)
for other wavelets - integrals of decomposition and reconstruction wavelet functions and a corresponding x-grid:
[int_psi_d, int_psi_r, x_grid] = integrate_wavelet(wavelet, precision)
Central frequency of psi

Quadrature Mirror Filter¶
Orthogonal Filter Banks¶
Example Datasets¶
The following example datasets are available in the module pywt.data
:
name description ecg ECG waveform (1024 samples) aero grayscale image (512x512) ascent grayscale image (512x512) camera grayscale image (512x512) nino sea surface temperature (264 samples)
Each can be loaded via a function of the same name.
Example: .. sourcecode:: python
>>> import pywt
>>> camera = pywt.data.camera()
