sigpy.linop.Wavelet

class sigpy.linop.Wavelet(ishape, axes=None, wave_name='db4', level=None)

Wavelet transform linear operator.

Currently only has CPU implementation. GPU inputs will be copied to CPU, and back to compute on CPU.

Parameters:

• ishape (tuple of int) – Input shape.
• axes (None or tuple of int) – Axes to perform wavelet transform.
• wave_name (str) – Wavelet name.
• level (None or int) – Number of wavelet levels.

__init__(ishape, axes=None, wave_name='db4', level=None)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(ishape[, axes, wave_name, level])	Initialize self.
apply(input)	Apply linear operation on input.

Attributes

H	Return adjoint linear operator.
N	Return normal linear operator.
