# Train-time image augmentation

Train-time image augmentation is a processing step in the DataRobot blueprint that creates new images for training by randomly transforming existing images, thereby increasing the size of (i.e., "augmenting") the training data. These sections describe components of augmentation, the process in which each image is transformed.
