SaltNoisePerturber

class nrtk.impls.perturb_image.photometric.noise.SaltNoisePerturber(*, seed: int | None = None, is_static: bool = False, amount: float = 0.05, clip: bool = True)

Adds salt noise to image stimulus.

Attributes:

seed (int | None):

Random seed for reproducible results. None means non-deterministic.

is_static (bool):

If True and seed is set, resets RNG state after each perturb call.

clip (bool):

Decide if output is clipped between the range of [-1, 1].

amount (float):

Proportion of image pixels to replace with salt noise on range [0, 1]

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 _SPNoisePerturber 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 salt 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]
