cr.sparse.lop.dwt2D¶
- cr.sparse.lop.dwt2D(shape, wavelet='haar', level=1, axes=None, basis=False)[source]¶
Returns a 2D Discrete Wavelet Transform operator
- Parameters
shape (tuple) – Shape of input image / output coefficients
wavelet (string) – Name of the discrete wavelet to be used
level (int) – Number of wavelet decompositions (default 1)
axes (tuple) – For multi-dimensional array input, the pair of axes along which the linear operator will be applied
basis (bool) – If False, the transform operator is returned. If True, the wavelet basis operator is returned instead. Default False.
- Returns
A linear operator wrapping 2D DWT transform or basis
- Return type
