MHT (Multiple Hypothesis Tracking)

Multiple Hypothesis Tracking (MHT) is a method used in surveillance and radar systems to track multiple objects simultaneously. It works by considering various possible interpretations of the data—like different paths or identities of objects—and generating multiple hypotheses about which measurements correspond to which objects. As new data arrives, MHT updates these hypotheses, gradually narrowing down the most probable tracking scenarios. This approach helps accurately follow multiple targets even in cluttered environments or when objects are close together, by continuously evaluating and refining possible trajectories to maintain reliable tracking information.
