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： A method for determining a parking violation includes receiving video data as a sequence of frames provided by a camera. The method includes defining a location of an exclusion zone in the video data. The method includes detecting a vehicle located in the defined exclusion zone. The detecting includes determining a background in an initial frame of the video data and determining a background in a select frame by applying a predetermined updating process. The detecting includes subtracting the background of the select frame from the initial frame to obtain an image difference. The detecting includes classifying the pixels in the image difference as foreground or background pixels and classifying the pixels in the foreground image as vehicle or non-vehicle pixels. The method includes determining a duration that the detected vehicle is in the exclusion zone based on a number of the sequence of frames including the detected vehicle.

摘要： A method for determining parking availability includes receiving video data from a sequence of frames taken from an image capture device that is monitoring a parking area. The method includes determining background and foreground images in an initial frame of the sequence of frames. The method further includes updating the background and foreground images in each of the sequence of frames following the initial frame. The method also includes determining a length of a parking space using the determined background and foreground images. The determining includes computing a pixel distance between a foreground image and one of an adjacent foreground image and an end of the parking area. The determining further includes mapping the pixel distance to an actual distance for estimating the length of the parking space.

摘要： Systems and methods are described that facilitate compensating for slow scan direction displacement (e.g., skew and/or bow) defects in a raster line using slow-scan electronic registration. Input image data is buffered at low-resolution (e.g., 600 spi or the like). Displacement compensation is performed as the low-resolution contone image data is converted to high-resolution (e.g., 2400 spi or the like), and a displaced (e.g., staggered) halftoning threshold array is indexed to account for detected displacement. Displacement compensation is again performed during conversion of the high-resolution contone image data to high-resolution binary image data that is used to generate an output image.

摘要： Embodiments described herein are directed to detecting and/or measuring distortions of substrate media that can occur during a printing process. The distortion can be detected and/or measured using a composite image generated from a reference image having a first periodic pattern and print image, disposed on a test substrate media, having a second periodic pattern. The first and second periodic patterns are specified so that the composite image includes a moiré pattern having moiré fringes resulting from interference between the first periodic pattern associated with the reference image and the second periodic pattern associated with the print image. The moiré fringes can be used to detect and calculate an amount of distortion of the test substrate media.

摘要： An automated method and system for detecting the presence of a smoking product utilizing a near infrared video-processing unit in real time. One or more near infrared (NIR) video capturing units can be configured to capture a video feed. The video feed can be processed by the video-processing unit in order to detect a smoking product (e.g., a lit cigarette) within a field of view of the video capturing unit. A near infrared video sequence can be read and analyzed for the presence of a “hot spot” of a predetermined size based on pixel color information. In some cases, the motion of the hot spot can be tracked in response to the detection of the hot spot. An alarm signal can also be triggered in some cases, if the pattern of motion is consistent with that of a cigarette being smoked.

摘要： A watermark is provided for use with images or image portions, such as saturated text. The watermark is provided as a modulation to the optical density of a public image or image portion wherein both modulated and unmodulated portions of the public image or image portion have an optical density that is beyond a threshold optical density beyond which the human visual system has a low sensitivity to optical density variations. Alternatively, the modulation is made at such a low amplitude as to be difficult to perceive by the human visual system. The modulation may be applied via an overprinting operation. Alternatively the modulation may be applied to image data prior to printing.
