    摘要: Vector halftoning and error diffusion are combined to provide a quantization method that yields high quality rendered images while demanding fewer system resources. For instance, the method is tolerant of resolution reductions in secondary or auxiliary channels to the vector halftoning process. Accordingly, these secondary pixel data channels can be sub-sampled and/or bit-depth reduced for transmission bandwidth conservation and/or reduction in data storage requirements. Restoring the resolution of the low resolution channels provides estimated image data to arrange or align with high resolution target channel data for the vector halftoning process. Error from marking decisions generated by the vector halftoning process is diffused to neighboring unprocessed pixels. The method also allows for the use of a small vector halftone threshold array while providing quantized images with fine texture and wide color gamuts. In some embodiments error diffusion is distributed according to vector error diffusion.

    摘要: Images are prepared for blending with a reflection. Angles of incidence and angles or reflection lead to reflections of a viewer appearing to be different than actual size. Accordingly, image preparation can include scaling images of objects to be blended with a reflection to an appropriate size. For a flat specular surface the size is one half the size the object would be if the object were sized to be associated with the feature that is reflected. A viewer will focus on the reflection of the viewer at an object plane. An image associated with the specular surface will be blurred. Accordingly, the preparation can include compensating for the blurring. Preparation can also include reducing an area coverage of the image of the object to no more than about fifty percent of the region of the refection to provide space for the reflection.

    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: 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.
