SpeckleNoisePerturber#

class nrtk.impls.perturb_image.photometric.noise.SpeckleNoisePerturber(*, seed: int | None = None, is_static: bool = False, mean: float = 0.0, var: float = 0.05, clip: bool = True)#

Adds multiplicative noise to image stimulus. Noise is Gaussian-based.

Methods

`from_config`	Instantiate a new instance of this class given the configuration JSON-compliant dictionary encapsulating initialization arguments.
`get_config`	Returns the current configuration of the _GSNoisePerturber instance.
`get_default_config`	Generate and return a default configuration dictionary for this class.
`get_impls`	Discover plugins, skipping any entrypoints that fail to load.
`get_type_string`	Returns the fully qualified type string of the PerturbImage class or its subclass.
`is_usable`	Check whether this class is available for use.
`perturb`	Return image stimulus with Speckle noise.

perturb(*, image: ndarray[Any, Any], boxes: Iterable[tuple[AxisAlignedBoundingBox, dict[Hashable, float]]] | None = None, **kwargs: Any) → tuple[ndarray[Any, Any], Iterable[tuple[AxisAlignedBoundingBox, dict[Hashable, float]]] | None]#: Return image stimulus with Speckle noise.
