20120207340 | METHOD FOR AUTOMATED TIRE DETECTION AND RECOGNITION - Methods and systems for discriminating between tires. One or more images of an unknown tire are received. One or more tread features are extracted from the images. The class of the unknown tire is determined using a classifier that matches the tread features to known tread features. | 08-16-2012 |

20130236063 | MULTIPLE VIEW TRANSPORTATION IMAGING SYSTEMS - A camera may be positioned to have a direct view of on-coming vehicle traffic from a first perspective. Additionally, a reflective surface, such as a mirror, may be positioned within the viewing area of the same camera to provide the camera with a reflected view of vehicle traffic from a second perspective. The images recorded by the camera may then be received by a computing device. The computing device may separate the images into a direct view region and a reflected view region. After separation, the regions may be analyzed independently and/or combined with other regions, and the analyzed data may be stored. The regions may be analyzed to determine various vehicle characteristics, including, but not limited to, vehicle speed, license plate identification, vehicle occupancy, vehicle count, and vehicle type. | 09-12-2013 |
20140063263 | SYSTEM AND METHOD FOR OBJECT TRACKING AND TIMING ACROSS MULTIPLE CAMERA VIEWS - A system and method for object tracking and timing across multiple camera views includes local and global tracking modules for tracking the location of objects as they traverse particular regions of interest within an area of interest. A local timing module measures the time spent with each object within the area captured by a camera. A global timing module measures the time taken by the tracked object to traverse the entire area of interest or the length of the stay of the object within the area of interest. | 03-06-2014 |
20140267733 | SINGLE CAMERA VIDEO-BASED SPEED ENFORCEMENT SYSTEM WITH A SECONDARY AUXILIARY RGB TRAFFIC CAMERA - When performing video-based speed enforcement a main camera and a secondary RGB traffic camera are employed to provide improved accuracy of speed measurement and improved evidentiary photo quality compared to single camera approaches. The RGB traffic camera provides sparse secondary video data at a lower cost than a conventional stereo camera. The sparse stereo processing is performed using the main camera data and the sparse RGB camera data to estimate a height of one or more tracked vehicle features, which in turn is used to improve speed estimate accuracy. By using secondary video, spatio-temporally sparse stereo processing is enabled specifically for estimating the height of a vehicle feature above the road surface. | 09-18-2014 |
20150063628 | ROBUST AND COMPUTATIONALLY EFFICIENT VIDEO-BASED OBJECT TRACKING IN REGULARIZED MOTION ENVIRONMENTS - A method and system for video-based object tracking includes detecting an initial instance of an object of interest in video captured of a scene being monitored and establishing a representation of a target object from the initial instance of the object. The dominant motion trajectory characteristic of the target object are then determined and a frame-by-frame location of the target object can be collected in order to track the target object in the video. | 03-05-2015 |
20150070471 | DETERMINING SOURCE LANE OF MOVING ITEM MERGING INTO DESTINATION LANE - Methods and devices acquire images using a stereo camera or camera network aimed at a first location. The first location comprises multiple parallel primary lanes merging into a reduced number of at least one secondary lane, and moving items within the primary lanes initiate transactions while in the primary lanes and complete the transactions while in the secondary lane. Such methods and devices calculate distances of the moving items from the camera to identify in which of the primary lanes each of the moving items was located before merging into the secondary lane. These methods and devices then order the transactions in a merge order corresponding to a sequence in which the moving items entered the secondary lane from the primary lanes. Also, the methods and devices output the transactions in the merge. | 03-12-2015 |
