Abstract: Methods and systems for automatically managing parking payment and enforcement. In general, real-time data regarding vehicles located in a parking zone can be acquired. The number of vehicles in the parking zone can be determined from the acquired real-time data. From such data, the number of vehicles in the parking zone that are paid can be calculated. Then, an operation can be implemented to compare the number of the vehicles in the parking zone with the number of vehicles in the parking zone that are paid with respect to the current time to determine unpaid violations if the number of vehicles in the parking zone exceeds the number of vehicles that are paid.

Abstract: Methods and systems for detecting an object borderline. A first image with respect to the object can be captured by an image-capturing unit without a flash light and borderlines of the object can be detected. If the detection is successful, the detected borderlines can be outputted. Otherwise, a second image with respect to the object can be captured by the image-capturing unit by applying a flash light and the borderlines can be detected in the image. A geometric transformation between the two images can then be estimated. Finally, the border lines in the first image can be determined by transforming the borderlines detected in the second image. Such an approach effectively detects the appliance borderlines and avoids artifacts caused by applying flash.

Abstract: A method and apparatus for obtaining an image and providing one or more document files to a user is disclosed. The method may include receiving an image of a target object using an imaging device, analyzing the image to identify one or more features, and accessing a model database to identify an object model having features that match the identified features from the image. When the system determines that more than one model may be a match, the method looks for distinguishing features of the target object and selects a model that includes the distinguishing features. The method then includes, retrieving a document file that corresponds to the identified model from a file database, and providing the document file to a user.

Abstract: Methods, systems and processor-readable media for identifying a vehicle for street parking management. An initial identification of one or more vehicles detected parked along a street can be generated based on one or more of a group of factors. The initial identification can be communicated to a user of the vehicle by transmitting an image indicative of the vehicle parked along the street (e.g., via a mobile communications device). An operation can then be implemented for requesting a confirmation or a non-confirmation as to whether the vehicle detected and displayed on the image is associated with the user. Upon confirmation, an operation can be implemented for identifying the at least one vehicle as the initial identification. Upon non-confirmation, an operation can be implemented to query to identify the vehicle associated with the user from among a group of vehicles displayed via the image.

Abstract: A method and system for determining one or more dimension estimations for a vehicle. A sequence of image frames of a vehicle is received, and a digital representation of the vehicle is extracted from each image in the sequence of image frames. A bounding box is determined for the vehicle based upon the extracted digital representation for each digital representation of the vehicle and at least one dimension of the vehicle is estimated based upon the determined bounding box. An indication of the at least one estimated dimension is output. The indication of at least one estimated dimension is transferred as an input to a comparison technique for further processing the indication of the at least one estimated dimension. The comparison technique can include a parking determination process configured to determine a recommended spot for the vehicle based upon the indication of the at least one estimated dimension.
