Abstract
Methods and systems for enhanced object tracking by receiving sensor fusion data related to target objects and object tracks; determining splines representing trajectories of each target object; filtering the sensor fusion data about each target object based on a first, second and third filtering model wherein each filtering model corresponds to one or more of a set of hypotheses used for processing vectors related to trajectories of a track object wherein the set of hypotheses comprise: a path constraint, a path unconstrained, and a stationary hypothesis; and generating a hypothesis probability for determining whether to use a particular hypothesis based wherein the hypothesis probability is determined based on results from the first, second and third filtering models and from results from classifying, by at least one classification model, one or more features related to the object track for the target object.
