1. A method for classifying a vehicle occupant into one of a plurality of occupant classes, comprising:
- producing a series of edge images of the vehicle occupant;
filtering across the series of edge images to produce a static edge image;
extracting a plurality of features from the static edge image; and
selecting an occupant class for the vehicle occupant according to the extracted plurality of features.

Abstract
System and methods are provided for classifying an occupant of a vehicle. An edge image generation component (102) produces an edge image of a vehicle occupant. A long term filtering component (104) filters across a plurality of edge images to produce a static edge image. A feature extraction component (106) extracts a plurality of features from the static edge image. A classification component (108) selects an occupant class for the vehicle occupant according to the extracted plurality of features.
