1. A method for vehicle classification comprising:
- performing a Bayesian network analysis for vehicle classifications, which are known, wherein the Bayesian network is defined as a directed acyclic graph G=(V, E), where nodes represent random variables from a domain of interest and arcs symbolize direct dependencies between the random variables.

Abstract
A system and method for classification of passenger vehicles and measuring their properties, and more particularly to a stochastic multi-class vehicle classification system, which classifies a vehicle (given its direct rear-side view) into one of four classes Sedan, Pickup truck, SUV/Minivan, and unknown, and wherein a feature pool of tail light and vehicle dimensions is extracted which feeds a feature selection algorithm to define a low-dimensional feature vector, and the feature vector is then processed by a Hybrid Dynamic Bayesian Network (HDBN) to classify each vehicle.
