AUTOMATED VEHICLE RECOGNITION
First Claim
1. A method of identifying a vehicle, the method comprising:
- obtaining from at least one camera at least one image of a vehicle;
using an image processor to derive from the at least one image a first sub-image and a second sub-image distinct from the first sub-image;
extracting from the first sub-image a first set of image features;
extracting from the second sub-image a second set of image features;
matching the first set of image features to corresponding image features derived from a previously obtained image of a vehicle to produce a first matching score;
matching the second set of image features to corresponding image features derived from a previously obtained image of a vehicle to produce a second matching score; and
fusing the first matching score and the second matching score to produce a fused score which indicates whether the at least one image is of the same vehicle as the previously obtained image.

Abstract
A system for identifying a vehicle. A camera obtains at least one image of a vehicle. An image processor derives from the image a first sub-image and a second sub-image distinct from the first sub-image, extracts from the first sub-image a first set of image features, and extracts from the second sub-image a second set of image features. The image processor matches the first set of image features to corresponding image features derived from a previously obtained image of a vehicle to produce a first matching score, and also matches the second set of image features to corresponding image features derived from a previously obtained image of a vehicle to produce a second matching score. The image processor then fuses the first matching score and the second matching score to produce a fused score which indicates whether the at least one image is of the same vehicle as the previously obtained image.
