PreprocessingExecutor class

dlf.core.preprocessing.PreprocessingExecutor(preprocessing_methods)

Object that applies a list of preprocessing methods to images,masks and boxes

Arguments

• preprocessing_methods: [PreprocessingMethod]. List of preprocessing methods which should be applied

---

PreprocessingJob class

dlf.core.preprocessing.PreprocessingJob(image, mask=None, boxes=None)

A container that hosts images, masks and bounding boxes for preprocessing

Arguments

• image: tf.tensor. Image that should be preprocessed
• mask: tf.tensor, optional. Mask that should be preprocessed. Defaults to None.
• boxes: tf.tensor, optional. Bounding Boxes to preprocess. Defaults to None.

call method

PreprocessingMethod.__call__(processing_job: dlf.core.preprocessing.PreprocessingJob)

Executed during preprocessing step

Args

• processing_job: PreprocessingJob. Job that should be preprocessed
