Patent Images
1. An object classification method comprising the steps of:
- capturing a video frame with an imaging device and examining a radar-cued potential object location within the video frame;
extracting orthogonal moment features from the potential object location;
extracting Gabor filtered features from the potential object location; and
classifying the potential object location into one of a first type of image or a second type of image in view of the extracted orthogonal moment features and the Gabor filtered features.

Abstract
An object classification method for a collision warning system is disclosed. The method includes the steps of capturing a video frame with an imaging device and examining a radar-cued potential object location within the video frame, extracting orthogonal moment features from the potential object location, extracting Gabor filtered features from the potential object location, and classifying the potential object location into one of a first type of image or a second type of image in view of the extracted orthogonal moment features and the Gabor filtered features.
