The technique of labeling or tagging video clips is known as video annotation, and it is used to train computer vision models to recognize or detect objects. In contrast to picture annotation, object recognition for machine learning models is achieved through frame-by-frame annotation of video objects.

For the best machine learning performance, ground truth datasets are produced by high-quality video annotation. Deep learning is being used for video annotation in a wide range of areas, such as geospatial technology, medical AI, and self-driving automobiles.
