Publication number: 20140270353Abstract: Methods, systems, and processor-readable media for pruning a training dictionary for use in detecting anomalous events from surveillance video. Training samples can be received, which correspond to normal events. A dictionary can then be constructed, which includes two or more classes of normal events from the training samples. Sparse codes are then generated for selected training samples with respect to the dictionary derived from the two or more classes of normal events. The size of the dictionary can then be reduced by removing redundant dictionary columns from the dictionary via analysis of the sparse codes. The dictionary is then optimized to yield a low reconstruction error and a high-interclass discriminability.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Applicant: Xerox CorporationInventors: Raja Bala, Zhigang Fan, Aaron Michael Burry, Jose Antonio Rodriguez-Serrano, Vishal Monga, Xuan Mo

Patent number: 8774462Abstract: Images with respect to an object at an ordering, payment, and delivery locations can be captured utilizing an image capturing system. Capture can be after detecting the presence of the object at each location utilizing an object presence sensor. The captured image can be processed to associate it with a signature and can also be processed in order to extract a small region of interest (e.g., license plate) and can be reduced to a unique signature. Signature can be stored into a database together with the corresponding order and images. Signatures can be matched. The order associated with the object matched by the system together with at least one of the images captured at the delivery point and the order point can be displayed at a user interface located at the payment/delivery point to ensure that the right order is delivered to the right customer associated with the object.Type: GrantFiled: February 15, 2013Date of Patent: July 8, 2014Assignee: Xerox CorporationInventors: Vladimir Kozitsky, Aaron Michael Burry, Zhigang Fan, Frank Bradley Mayberry, John Deppen

Publication number: 20140079315Abstract: Methods and systems for reducing the required footprint of SNoW-based classifiers via optimization of classifier features. A compression technique involves two training cycles. The first cycle proceeds normally and the classifier weights from this cycle are used to rank the Successive Mean Quantization Transform (SMQT) features using several criteria. The top N (out of 512 features) are then chosen and the training cycle is repeated using only the top N features. It has been found that OCR accuracy is maintained using only 60 out of 512 features leading to an 88% reduction in RAM utilization at runtime. This coupled with a packing of the weights from doubles to single byte integers added a further 8× reduction in RAM footprint or a reduction of 68× over the baseline SNoW method.Type: ApplicationFiled: January 22, 2013Publication date: March 20, 2014Applicant: XEROX CORPORATIONInventors: Vladimir Kozitsky, Aaron Michael Burry, Peter Paul

Publication number: 20130294654Abstract: A method and system for achieving accurate segmentation of characters with respect to a license plate image within a tight bounding box image. A vehicle image can be captured by an image capturing unit and processed utilizing an ALPR unit. A vertical projection histogram can be calculated to produce an initial character boundary (cuts) and local statistical information can be employed to split a large cut and insert a missing character. The cut can be classified as a valid and/or a suspect character and the suspect character can be analyzed. The suspect character can be normalized and passed to an OCR module for decoding and generating a confidence quote with every conclusion. The non-character images can be rejected at the OCR level by enforcing a confidence threshold. An adjoining suspect narrow character can be combined and the OCR confidence of the combined character can be assessed.Type: ApplicationFiled: July 2, 2012Publication date: November 7, 2013Applicant: XEROX CORPORATIONInventors: Aaron Michael Burry, Claude Fillion, Vladimir Kozitsky

Publication number: 20130279758Abstract: Methods, systems and processor-readable media for robust tilt adjustment and cropping of a license plate image. A vehicle image can be captured by an image-capturing unit and converted to a binary image utilizing a binarization approach. A long run within the binary image can then be removed and a morphological filtering can be applied to break an unwanted connection between characters due to a license plate frame and an image noise. A connected component (CC) within the image can be identified and screened based on a number of key metrics to remove a most likely candidate character connected component. A line-fit based iterative search process can then be performed for robust tilt removal and vertical cropping of the license plate image to obtain a tight bounding box on the license plate characters if sufficient candidate characters remain after the search process. Otherwise, the region of interest can be rejected.Type: ApplicationFiled: April 23, 2012Publication date: October 24, 2013Applicant: XEROX CORPORATIONInventors: Aaron Michael Burry, Claude Fillion, Vladimir Kozitsky, Zhigang Fan

Publication number: 20130282420Abstract: Embodiments relate to systems and methods for realtime occupancy detection of vehicles approaching a retail site for predictive ordering. A restaurant or other retail site can maintain access areas, such as a drive through lane or parking area, which vehicles can approach to order food or other items. A set of sensors can detect the vehicles, and estimate the number of occupants in those vehicles. Detection techniques can include face detection technology, seat detection technology, thermal imaging, or others. The number of occupants can be estimated and sent to a production management engine monitoring the site. That engine can responsively issue production instructions, such as a number and type of food items to prepare, and when. By integrating an operational model of the site, including projected order amounts and types, with the realtime occupant count, more accurate matching of food or other production to customer demand can be achieved.Type: ApplicationFiled: April 20, 2012Publication date: October 24, 2013Applicant: XEROX CORPORATIONInventors: Peter Paul, Aaron Michael Burry, Joel Eagle

Publication number: 20130272579Abstract: A method, system, and computer-usable tangible storage device for robustly cropping and accurately recognizing license plates to account for noise sources and interfering artifacts are disclosed. License plate images and sub-images can be tightly cropped utilizing an image-based classifier and gradient-based cropping. An image-based classifier can identify the location of valid characters within the image. Because of a number of noise sources, such as, for example, residual plate rotation and shear in the characters within the image, the image-based classifier performs a “rough” identification of the image boundaries. An additional processing step utilizing gradient-based cropping is performed to fine-tune the license plate image boundaries. Gradient-based cropping eliminates unwanted border artifacts that could substantially impact the segmentation and license plate character recognition results.Type: ApplicationFiled: April 17, 2012Publication date: October 17, 2013Applicant: Xerox CorporationInventors: Aaron Michael Burry, Claude Fillion, Vladimir Kozitsky, Raja Bala, Zhigang Fan
