METHODS AND SYSTEMS FOR IMPROVING YIELD IN WANTED VEHICLE SEARCHES
First Claim
1. A computer-implemented method of detecting a target vehicle, the method comprising:
- receiving identification information associated with a target vehicle;
generating, using a processor, a set of target signatures, wherein generating the set of target signatures comprises;
generating a set of synthetic license plate images using the identification information; and
for each synthetic license plate image in the set of synthetic license plate images, calculating a target signature representing a signature of the synthetic license plate image;
receiving an authentic license plate image, wherein the authentic license plate image was captured by a camera at a location;
calculating a search signature representing a signature of the authentic license plate image;
determining that the search signature matches a target signature from among the set of target signatures; and
determining that the target vehicle was detected at the location based on determining that the search signature matches the target signature.

Abstract
In response to determining that a target vehicle is at large, identification information associated with the target vehicle'"'"'s license plate may be retrieved and used to generate one or more synthetic license plate images. The synthetic license plate images may be subjected to one or more transformation to cause them to resemble authentic license plate image captures and/or to mimic authentic license plate image captures from existing and operational ALPR system cameras. Target signatures may then be calculated from the synthetic license plate images. Upon capturing an authentic license plate image using an ALPR system camera, a signature of the authentic license plate image may be calculated. If a match is found between the signature of the authentic license plate image and a target signature, law enforcement may be alerted that the target vehicle was detected at the location of the ALPR system camera.

11. A system configured to implement to detect a target vehicle, the system comprising:
-
a processing system comprising one or more processors; and a memory system comprising one or more computer-readable media, wherein the computer-readable media contain instructions stored thereon that, when executed by the processing system, cause the processing system to perform operations comprising; receiving identification information associated with a target vehicle; generating a set of target signatures, wherein generating the set of target signatures comprises; generating a set of synthetic license plate images using the identification information; and for each synthetic license plate image in the set of synthetic license plate images, calculating a target signature representing a signature of the synthetic license plate image; receiving an authentic license plate image, wherein the authentic license plate image was captured by a camera at a location; calculating a search signature representing a signature of the authentic license plate image; determining that the search signature matches a target signature from among the set of target signatures; and determining that the target vehicle was detected at the location based on determining that the search signature matches the target signature. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
