Particle Filter

May 1, 2024 3 minute read

Particle Filter is a Monte Carlo method that is used to estimate the state of a dynamic system from a sequence of noisy observations. It is a powerful tool for tracking objects in video, localizing robots, and performing other tasks that require real-time estimation of a system's state.

How Particle Filter Works

Particle Filter works by representing the state of the system as a set of particles. Each particle is a possible state of the system, and the weight of each particle represents the probability that the particle is the true state of the system. The particles are then updated over time based on the observations that are received. The particles that are more consistent with the observations are given higher weights, while the particles that are less consistent with the observations are given lower weights. This process is repeated over time, until the particles converge to the true state of the system.

Applications of Particle Filter

Particle Filter has a wide range of applications, including:
