Patent Images
1. A computer-implemented method of classifying a vehicle captured with an image capturing device, the image capturing device oriented to include a field of view spanning a vehicle detection target region, the method comprising:
- a) generating a cluster of motion vectors representative of a vehicle detected within the target region;
b) associating one or more attributes with the cluster of motion vectors; and
c) classifying the vehicle detected according to the one or more attributes associated with the cluster of motion vectors.

Abstract
This disclosure provides methods and systems of classifying a vehicle using motion vectors associated with captured images including a vehicle. According to an exemplary method, a cluster of motion vectors representative of a vehicle within a target region is analyzed to determine geometric attributes of the cluster and/or measure a length of a detected vehicle, which provides a basis for classifying the detected vehicle.
