NOPPerturber

class nrtk.impls.perturb_image.generic.nop_perturber.NOPPerturber(box_alignment_mode: str = 'extent')

Example implementation of the PerturbImage interface.

An instance of this class acts as a functor to generate a perturbed image for the given input image stimulus.

This class, in particular, serves as pass-through “no operation” (NOP) perturber.

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 PerturbImage 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`	Return unperturbed image.
