Which of the following describes a typical use case of video tracking?

Video tracking involves locating and following a moving object (or multiple objects) over time using a camera. Traffic monitoring is a classic and widespread application of this technology. In this use case, computer vision systems are deployed to track vehicles on roads to count traffic volume, measure average speed, detect incidents like accidents or stopped cars, and analyze traffic patterns. This information is crucial for intelligent transportation systems, traffic management, and urban planning.

A. Augmented dreaming: This is a speculative or fictional concept and not a recognized technological application of video tracking.
B. Medical diagnosis: While computer vision is used to analyze static medical images (e.g., X-rays), video tracking is less typical for diagnosis itself, though it has niche uses like gait analysis.
D. Video composition: This refers to the process of video editing. While motion tracking can be a feature in editing software, it is not the primary use case of the core technology.
