A traffic violation processing method is disclosed, which includes the steps of monitoring a vehicle; determining whether the vehicle is in violation of a traffic violation and recording the image of the vehicle on a camera when the vehicle is determined to have violated a traffic violation; providing a digital image of the vehicle; recording and storing deployment data corresponding to the violation, wherein the deployment data includes an identifier associated with the traffic violation; assigning the identifier to the digital traffic image; storing the digital image of the vehicle, together with the identifier, on a storage medium; matching the deployment data with the stored digital image by correlating or matching the identifier associated with the deployment data with the identifier associated with the stored digital image; and generating a traffic document that includes the stored digital image and the deployment data.

Traffic violation processing system

A system and method are disclosed for determining and applying a discount to a customer's transaction. The discount is of a progressive nature, wherein the value of a customer's discount increases if the customer meets the conditions associated with the discount. The system rewards more frequent or profitable customers with benefits such as larger increases in the discount or higher maximum discount than those awarded to less frequent or profitable customers. The discount is decreased or eliminated if the customer fails to meet the conditions associated with the discount.

Method and apparatus for determining a progressive discount for a customer based on the frequency of the customer's transactions

A server or Internet service provider computer selects a soliciting merchant and an outputting merchant based on various factors. In one embodiment, the soliciting merchant is selected is its activity rate (e.g. sales rate) is low. The outputting merchant provides offers for bonuses to customers on behalf of the soliciting merchant. The bonus is provided to the customer in exchange for consummating a transaction with the soliciting merchant. Thus, the soliciting merchant benefits from the increased patronage such offers encourage.

Method and apparatus for defining routing of customers between merchants

A motion-estimation scheme is provided that employs a combination of motion estimation and compensation techniques. Low resolution images are computed from two consecutive image frames, and feature points are determined and matched between the two low resolution images. Statistical methods are used to estimate the motion in terms of a translation and rotation of the image plane. Corresponding feature points in the original images are matched, based on the estimated motion of the low-resolution images. Statistical techniques are then applied to determine a homography matrix that describes the motion between the corresponding feature points in the original images, and this matrix is used to align the original images. Differences between the aligned images are identified, to indicate the movement of one or more objects in the image.

Motion-based tracking with pan-tilt zoom camera

A method for reading a license plate disposed on a vehicle includes determining whether a license plate image is required, automatically processing the license plate image in response to determining that the license plate image is required, providing at least one verified image, and determining whether to manually read the license plate image by matching the license plate image with the at least one verified image.

System and method for reading license plates

An automated license plate locator and reader (10) which provides novel methods for 1) correcting for perspective distortion (16), 2) locating the license plate (20), 3) reading the license plate (22) and 4) improving the confidence rating of the output signal (228) The novel method for accommodating a wide range of viewing geometries involves warping the image to eliminate perspective distortion of the plate resulting from roadside camera placement The novel method for locating plates involves correlating an "idealized" edge template of a license plate with an edge-enhanced version of the image Edge enhancement and shadow reduction is achieved by applying a Laplacian operator over the input image Performance is further improved by filtering out distracting edges within the resulting correlation surface and then locating the highest peaks within this filtered correlation surface The location of the highest peaks provides the location of the plate The novel method for reading the license plates involves performing a modified binary correlation of an image of the plate with reference characters to provide output signals indicative of the symbols on the plate This output is correlated with valid license plate signals to improve the confidence rating thereof

Automated license plate locator and reader including perspective distortion correction

An automated license plate locator and reader (10) which provides novel methods for 1) correcting for perspective distortion (16), 2) locating the license plate (20), 3) reading the license plate (22) and 4) improving the confidence rating of the output signal (228). The novel method for accommodating a wide range of viewing geometries involves warping the image to eliminate perspective distortion of the plate resulting from roadside camera placement. The novel method for locating plates involves correlating an "idealized" edge template of a license plate with an edge-enhanced version of the image. Edge enhancement and shadow reduction is achieved by applying a Laplacian operator over the input image. Performance is further improved by filtering out distracting edges within the resulting correlation surface and then locating the highest peaks within this filtered correlation surface. The location of the highest peaks provides the location of the plate. The novel method for reading the license plates involves performing a modified binary correlation of an image of the plate with reference characters to provide output signals indicative of the symbols on the plate. This output is correlated with valid license plate signals to improve the confidence rating thereof.
