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.

Functions

• apply_affine_transform(...): Applies an affine transformation specified by the parameters given.
• apply_brightness_shift(...): Performs a brightness shift.
• apply_channel_shift(...): Performs a channel shift.
• array_to_img(...): Converts a 3D Numpy array to a PIL Image instance.
• img_to_array(...): Converts a PIL Image instance to a Numpy array.
• load_img(...): Loads an image into PIL format.
• random_brightness(...): Performs a random brightness shift.
• random_channel_shift(...): Performs a random channel shift.
• random_rotation(...): Performs a random rotation of a Numpy image tensor.
• random_shear(...): Performs a random spatial shear of a Numpy image tensor.
• random_shift(...): Performs a random spatial shift of a Numpy image tensor.
• random_zoom(...): Performs a random spatial zoom of a Numpy image tensor.
• save_img(...): Saves an image stored as a Numpy array to a path or file object.
