Dataset preprocessing - Keras
https://keras.io/api/preprocessingDataset preprocessing. Keras dataset preprocessing utilities, located at tf.keras.preprocessing, help you go from raw data on disk to a tf.data.Dataset object that can be used to train a model.. Here's a quick example: let's say you have 10 folders, each containing 10,000 images from a different category, and you want to train a classifier that maps an image to its category.
Image data preprocessing - Keras
https://keras.io/api/preprocessing/imageThen calling image_dataset_from_directory(main_directory, labels='inferred') will return a tf.data.Dataset that yields batches of images from the subdirectories class_a and class_b, together with labels 0 and 1 (0 corresponding to class_a and 1 corresponding to class_b).. Supported image formats: jpeg, png, bmp, gif. Animated gifs are truncated to the first frame.
