StackedPhysics#
- class deepinv.physics.StackedPhysics(physics_list: list[Physics], **kwargs)[source]#
Bases:
PhysicsStacks multiple physics operators into a single operator.
The measurements produced by the resulting model are
deepinv.utils.TensorListobjects, where each entry corresponds to the measurements of the corresponding operator.See Combining Physics for more information.
- Parameters:
physics_list (list[deepinv.physics.Physics]) – list of physics operators to stack.
- A(x: Tensor, **kwargs) TensorList[source]#
Computes forward of stacked operator
\[\begin{split}y = \begin{bmatrix} A_1(x) \\ A_2(x) \\ \vdots \\ A_n(x) \end{bmatrix}\end{split}\]- Parameters:
x (torch.Tensor) – signal/image
- noise(y: TensorList, **kwargs) TensorList[source]#
Applies noise to the measurements per physics operator in the stacked operator.
- sensor(y: TensorList, **kwargs) TensorList[source]#
Applies sensor non-linearities to the measurements per physics operator in the stacked operator.
