WebKeras’ ImageDataGenerator class allows the users to perform image augmentation while training the model. If you do not have sufficient knowledge about data augmentation, please refer to this tutorial which … WebKeras ImageDataGenerator class allows the specification of maximum height and width shifting range. If we set height_shift_range to 200, then the image would shift randomly between 200px up to 200px down. We can also set it to a floating number instead of an integer. A floating number of 0.20 means an image would shift a maximum of 20%.
