NRTK perturber CLI Entrypoint

nrtk-perturber

Generate NRTK perturbed images and detections from a given set of source images and COCO-format annotations.

Generate NRTK perturbed images and detections from a given set of source images and COCO-format annotations and write them to an output folder in disk. The perturbed images are stored in subfolders named after the chosen perturbation parameter keys and values.

DATASET_DIR - Root directory of dataset. OUTPUT_DIR - Directory to write the perturbed images to. CONFIG_FILE - Configuration file specifying the PerturbImageFactory configuration.

param dataset_dir:

Root directory of dataset.

param output_dir:

Directory to write the perturbed images to.

param config_file:

Configuration file specifying the PerturbImageFactory configuration.

param generate_config_file:

File to write default config file, only written if specified.

param verbose:

Display progress messages. Default is false.

Augmented MAITE dataset(s) generator

This module contains nrtk_perturber, which generates augemented MAITE dataset(s) based on a pertrber factory configuration

nrtk.interop.maite.utils.nrtk_perturber.nrtk_perturber(maite_dataset: Dataset, perturber_factory: PerturbImageFactory) → Iterable[tuple[str, Dataset]]

Generate augmented dataset(s) of type maite.protocols.object_detection.Dataset.

Generate augmented dataset(s) of type maite.protocols.object_detection.Dataset given an input dataset of the same type and a perturber factory implementation. Each perturber dcombination will result in a newly generated dataset.

Parameters:

• maite_dataset – A dataset object of type maite.protocols.object_detection.Dataset

• perturber_factory – PerturbImageFactory implementation.
