What is Video Person Tracking API ?

Video Person Tracking API is a tool that allows users to easily track people in videos by analyzing each frame, detecting people and keeping track of their movements throughout the video. The technology starts by identifying individuals in a video through person detection, then it continues by tracking them over time through their unique features such as facial features, clothing, or posture.

‍

Person Tracking API can be utilized as a standalone tool, or it can be integrated with face detection to achieve more precise results. This API can be used to analyze scenarios that are highly complex like crowded scenes with many people, or high-traffic areas like airports, train stations, and metro stations.
