Solver

class imgreg.util.solver.Solver(parameters: Optional[Set[imgreg.util.params.Parameter]] = None)

Bases: object

Interface for a Solvermodel constructed from a set of parameters.

Constructs a dependency graph for the Parameters of the model and allows for lazy evaluation of the Parameters.

Notes

The state of this class is cached, when a parameter is changed on which later states depend, the properties ascendant to said parameter are removed from the cache. Solver._get_dep_graph() allows access to the internal dependency graph representation.

Methods

__init__([parameters])	Initialize self.
display(param_list[, title])	Fancy plot functionality for registered ImageParameters.
dot_graph([node_args_func])	Return a dot graph representation of the solver model.

display(param_list: Sequence[Union[enum.Enum, imgreg.util.params.ImageParameter]], title: Optional[str] = None) → None

Fancy plot functionality for registered ImageParameters.

Parameters

plotlistsequence

sequence, to access the ImageParameters registered in solver

titlestr

str, contains title of overall plot

dot_graph(node_args_func: Callable[[imgreg.util.params.Parameter], Dict[str, str]] = <function dot_shape_func>) → graphviz.dot.Digraph

Return a dot graph representation of the solver model.
