 Before you can train a model on a dataset, it needs to be preprocessed into the expected model input format. Whether your data is text, images, or audio, they need to be converted and assembled into batches of tensors. 🤗 Transformers provides a set of preprocessing classes to help prepare your data for the model. In this tutorial, you'll learn that for:
 
 * Text, use a [Tokenizer](./main_classes/tokenizer) to convert text into a sequence of tokens, create a numerical representation of the tokens, and assemble them into tensors.
-* Image inputs use a [ImageProcessor](./main_classes/image) to convert images into tensors.
 * Speech and audio, use a [Feature extractor](./main_classes/feature_extractor) to extract sequential features from audio waveforms and convert them into tensors.
+* Image inputs use a [ImageProcessor](./main_classes/image) to convert images into tensors.
 * Multimodal inputs, use a [Processor](./main_classes/processors) to combine a tokenizer and a feature extractor or image processor.

+For computer vision tasks, you'll need an [image processor](main_classes/image_processor) to prepare your dataset for the model.
+Image preprocessing consists of several steps that convert images into the input expected by the model. These steps
+include but are not limited to resizing, normalizing, color channel correction, and converting images to tensors.
+
+<Tip>
+
+Image preprocessing often follows some form of image augmentation. Both image preprocessing and image augmentation
+transform image data, but they serve different purposes:
+
+* Image augmentation alters images in a way that can help prevent overfitting and increase the robustness of the model. You can get creative in how you augment your data - adjust brightness and colors, crop, rotate, resize, zoom, etc. However, be mindful not to change the meaning of the images with your augmentations.
+* Image preprocessing guarantees that the images match the model’s expected input format. When fine-tuning a computer vision model, images must be preprocessed exactly as when the model was initially trained.
+
+You can use any library you like for image augmentation. For image preprocessing, use the `ImageProcessor` associated with the model.

-For computer vision tasks, it is common to add some type of data augmentation to the images as a part of preprocessing. You can add augmentations with any library you'd like, but in this tutorial, you'll use torchvision's [`transforms`](https://pytorch.org/vision/stable/transforms.html) module. If you're interested in using another data augmentation library, learn how in the [Albumentations](https://colab.research.google.com/github/huggingface/notebooks/blob/main/examples/image_classification_albumentations.ipynb) or [Kornia notebooks](https://colab.research.google.com/github/huggingface/notebooks/blob/main/examples/image_classification_kornia.ipynb).

+<Tip>

+and leveraged the `size` attribute from the appropriate `image_processor`. If you do not resize images during image augmentation,
+leave this parameter out. By default, `ImageProcessor` will handle the resizing.

 ## Multimodal
 
 For tasks involving multimodal inputs, you'll need a [processor](main_classes/processors) to prepare your dataset for the model. A processor couples together two processing objects such as as tokenizer and feature extractor.
