etomo.operators.gradient.gradient

This module contains classes for defining gradients operators. Taken from pysap-mri with minor changes (name of parameters (data_op), change of data type to float).

class GradAnalysis(data_op)

Bases: modopt.opt.gradient.GradBasic, modopt.math.matrix.PowerMethod

Gradient operator for the data attachment term in the reconstruction process in analysis formulation

class GradSynthesis(linear_op, data_op)

Bases: modopt.opt.gradient.GradBasic, modopt.math.matrix.PowerMethod

Gradient operator for the data attachment term in the reconstruction process in synthesis formulation

_op_method(data, *args, **kwargs)

_trans_op_method(data, *args, **kwargs)
