ComposePerturber

class nrtk.impls.perturb_image.generic.compose_perturber.ComposePerturber(perturbers: list[PerturbImage] | None = None)

Composes multiple image perturbations by applying a list of perturbers sequentially to an input image.

Attributes:

perturbers (list[PerturbImage]):

List of perturbers to apply.

Note:

This class has not been tested with perturber factories and is not expected to work with perturber factories.

Methods

from_config	Create a ComposePerturber instance from a configuration dictionary.
get_config	Get the configuration dictionary of the ComposePerturber instance.
get_default_config	Generate and return a default configuration dictionary for this class.
get_impls	Discover and return a set of classes that implement the calling class.
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	Apply the sequence of perturbers to the input image.

__init__(perturbers: list[PerturbImage] | None = None) → None

Initializes the ComposePerturber.

This has not been tested with perturber factories and is not expected to work with perturber factories.

Args:

perturbers:

List of perturbers to apply.

classmethod from_config(config_dict: dict[str, Any], merge_default: bool = True) → Self

Create a ComposePerturber instance from a configuration dictionary.

Args:

config_dict:

Configuration dictionary with perturber details.

merge_default:

Whether to merge with the default configuration.

Returns:

return ComposePerturber:

An instance of ComposePerturber.

get_config() → dict[str, Any]

Get the configuration dictionary of the ComposePerturber instance.

Returns:

return dict[str, Any]:

Configuration dictionary containing perturber configurations.

perturb(image: ndarray[Any, Any], boxes: Iterable[tuple[AxisAlignedBoundingBox, dict[Hashable, float]]] | None = None, additional_params: dict[str, Any] | None = None) → tuple[ndarray[Any, Any], Iterable[tuple[AxisAlignedBoundingBox, dict[Hashable, float]]] | None]

Apply the sequence of perturbers to the input image.

Args:

image:

The input image to perturb.

boxes:

The bounding boxes for the input image. This is the single image output from DetectImageObjects.detect_objects.

additional_params:

Additional parameters for perturbation.

Returns:

return tuple[np.ndarray, Iterable[tuple[AxisAlignedBoundingBox, dict[Hashable, float]]] | None]:

The perturbed image and the source bounding boxes.
