摘要： A multi-beam laser ROS print system is described which is adapted to minimize banding in output prints. Multiple beams from a laser source are separated by a distance which causes the beam to scan consecutive lines in a non-consecutive scan; e.g., according to a particular beam interlacing sequence. It has been found that as a general proposition, banding decreases with increasing interlacing orders and, furhter, that once a print system error frequency, or another frequency of interest has been identified, there are a number of interlacing orders, each an optimum value, which can be introduced to reduce banding which would ordinarily result from the particular frequency error.

摘要： A printing system employing a raster output scanning device is compensated for the effects of motion of the medium upon which an image is being printed. An amplitude transmittance spatial filter is positioned either in an exit pupil of the "slow scan" optics of the system or in the first Fourier transform plane of a lens positioned between the scanning device and the recording medium. Several preferred transmittance functions are provided.

摘要： A short focal length lens array has a plurality of lenslets formed within the body of a photosensitive glass. The lenslets have areas which are oriented such that they tilt away from each other from the center out to the array edges. The lens array acts as a reduction or enlargement lens when reproducing objects at an object plane onto an image plane. A one or two row embodiment is disclosed suitable for incremental scanning of a document at image planes. A further full frame lens array is disclosed for providing full frame exposure of a document at various selected magnifications.

摘要： A method for enforcing traffic signal compliance includes acquiring a series of temporal related image frames including a target area. Each image frame includes pixel data representative of the target area. The method includes generating one or more motion vectors between two or more of the image frames. The motion vectors are the type produced by compressing the pixel data associated with the two or more image frames. The method includes associating a cluster of motion vectors with a vehicle. The method further includes tracking a position of the vehicle across the two or more image frames. Using the tracking results, the method includes determining whether the vehicle stops in the target area. For the vehicle being determined as not stopping, the method includes signaling an occurrence of noncompliance.

摘要： Automated low-complexity video-based vehicle speed estimation is described, that operates within the video stream to screen video sequences to identify and eliminate clear non-violators and/or identify and select potential violators within a multi-layer speed enforcement system, in which deeper layers provide enhanced accuracy on selected candidate (speeding) vehicles. Video motion vector clusters corresponding to a vehicle are identified and tracked across multiple frames of captured video. Movement of the motion vector clusters translated from pixels per second to real speed (e.g. miles per hour) to determine whether the vehicle was speeding. Estimated speed data is added to the video stream data is metadata, and video segments of candidate speeding vehicles are stored and/or transmitted for subsequent review (e.g. automated or manual).

摘要： This disclosure provides a video camera and video processing alert system for detecting a vehicle in reverse. According to one exemplary embodiment, the system operates according to the following guidelines or steps: (1) Acquire video containing features relevant to reverse detection, (2) Identify feature(s) within the video frame that are relevant to a vehicle in reverse, (3) Examine identified features to extract the evidence of vehicle backing up for a current frame, (4) Apply temporal filtering on the frame-to-frame evidence, (5) Use filtered evidence for decision on triggering the alarm, (6) Triggering an alarm if indicated by the decision. The system can be implemented with relative low cost and complexity, due to the affordability of video cameras, and the fact that many drive-through locations have existing video capture infrastructure.

摘要： 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.

摘要： A method and a system for determining a parking boundary violation includes receiving video data from a sequence of frames taken from an image capture device monitoring a parking area including at least a single parking space. A boundary is determined for defining at least one parking space in the parking area. A vehicle is detected in the parking area. A determination is made whether the detected vehicle is violating a parking regulation based on a position and size of the vehicle within the boundary.
