Estimation Filters

Kalman and particle filters, EKF, UKF, motion models, and IMM

Sensor Fusion and Tracking Toolbox™ provides estimation filters that are optimized for specific scenarios, such as linear or nonlinear motion models, linear or nonlinear measurement models, or incomplete observability.
