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.

摘要： A method for determining the occurrence of a short-term parking violation includes receiving video data in a sequence of frames provided by an image capture device monitoring a parking area over a duration of time. The method includes determining the presence of a vehicle captured in at least one of the sequence of frames. The method tracks the location of the vehicle across the sequence of frames. The method further determines a spatial location of the vehicle in each frame. The method includes determining spatio-temporal information describing the location of the vehicle as a function of time by associating the spatial location of the vehicle at each frame with the time instant at which the frame was captured. In response to the spatio-temporal information indicating that the vehicle becomes stationary, the method determines a duration that the vehicle is stationary using the determined spatio-temporal information of the vehicle.

摘要： A mechanism for providing edge enhancement or attenuation in a vector error diffusion process includes warping a marking decision color space as a function of at least one pixel value of a target pixel. The warping changes the membership of sets of error modified pixel values associated particular sets of marking. The warping is controlled by a function of pixel values of a target pixel from an input image. Therefore, the warping is constant for uniform portions of the image. Since pixel values change at edges or where colors change, a mechanism is provided for the presence of edges to influence the vector error diffusion process. Selection of the function by which the marking decision color space is warped provides a means for controlling the aggressiveness of the edge enhancement or attenuation. Equivalent processing includes warping or adjusting error modified pixel values according to corresponding functions.
