Trajectory Analysis and Semantic Region Modeling Using A Nonparametric Bayesian Model

Trajectory Analysis and Semantic Region Modeling Using A Nonparametric Bayesian Model

We propose a novel nonparametric Bayesian model, Dual Hierarchical Dirichlet Processes (Dual-HDP), for trajectory analysis and semantic region modeling in surveillance settings, in an unsupervised way. In our approach, trajectories are treated as documents and observations of an object on a trajecto...
