What is data annotation job?

Data annotation is the task of labeling data with metadata in preparation for training a machine learning model. Both data and metadata come in many forms, including content types such as text, audio, images, and video.

How do you annotate an image?

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.
