What is image annotation? Image annotation is the task of labeling digital images, typically involving human input and, in some cases, computer-assisted help. Labels are predetermined by a machine learning (ML) engineer and are chosen to give the computer vision model information about the objects present in the image.

In general, this is how image annotation works: Step #1: Prepare your image dataset. Step #2: Specify the class labels of objects to detect. Step #3: In every image, draw a box around the object you want to detect. Step #4: Select the class label for every box you drew.

Image annotation work typically includes the following tasks: Preparing the image dataset. Specifying object classes that annotators will use to label images. Assigning labels to images. Marking objects within each image by drawing bounding boxes. Selecting object class labels for each box.

What is image annotation? In machine learning and deep learning, image annotation is the process of labeling or classifying an image using text, annotation tools, or both, to show the data features you want your model to recognize on its own. When you annotate an image, you are adding metadata to a dataset.
