Module: tf.keras.preprocessing.image

Set of tools for real-time data augmentation on image data.

Classes

class DirectoryIterator: Iterator capable of reading images from a directory on disk.

class ImageDataGenerator: Generate batches of tensor image data with real-time data augmentation.

class Iterator: Base class for image data iterators.

class NumpyArrayIterator: Iterator yielding data from a Numpy array.
