  • Patent number: 8467099
    Abstract: As set forth herein, computer-implemented methods and systems facilitate halftoning by adapting 2nd generation halftone techniques to the spatial frequency content of an image utilizing a spot function introduced in conjunction with a technique for determining seed locations, which results in halftone images exhibiting improved edge and detail rendition. A dominant orientation of pixels in an input image is employed to select a pre-generated stochastic screen used to determine the seed locations.

  • Publication number: 20130148168
    Abstract: As set forth herein, computer-implemented methods and systems facilitate watermarking documents and/or images using 2nd generation stochastic halftoning. The watermark is used to spatially vary the gray level at which a frequency modulation-to-amplitude modulation transition occurs. The encoding algorithm uses as inputs a contone image and a watermark. The visibility of the watermark is controlled by the magnitude of the difference between the AM-to-FM transition threshold values.

  • Patent number: 8437036
    Abstract: A technique for cross-channel correction in real time for digital color printing in which the full resolution value of a selected colorant is combined with low resolution versions of the remaining colorants to provide a basis for correcting the selected colorant based upon the data for the other colorants employed. The pixel values of sub-samples of the remaining colorants are derived from the cell in which the full resolution selected colorant is taken; and, the desired output value is selected from a look-up table established for the known printing process.

  • Publication number: 20130106595
    Abstract: 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.

  • Publication number: 20130088600
    Abstract: Systems and methods are disclosed that include a video-based analysis system that detects, tracks and archives vehicles in video stream data at multiple resolutions. The system includes an image capturing device that captures video stream data having video at a first high resolution. A vehicle detection module detects at least one vehicle within the video. A vehicle analysis module is configured to analyze the video and to extract one or more key vehicle features from the video to enable identification of a vehicle of interest (VOI) according to a set of predetermined criteria. A subsampling module creates a reduced resolution video stream in a second subsampled resolution that is lower than the first high resolution while maintaining the one or more extracted key features within the reduced resolution video stream in the first high resolution, and archives the reduced resolution video stream into a video database.

  • Publication number: 20130083303
    Abstract: An imaging system utilizes an anamorphic optical system to concentrate a two-dimensional modulated light field in a process direction such that a one-dimensional scan line image extending in a cross-process direction is generated on an imaging surface. The modulated light field is generated by directing homogeneous light onto light modulating elements arranged in a two-dimensional array. The array is configured using a scan line image data group made up of pixel image data portions. An associated group of the light modulating elements aligned in the process direction is configured by each pixel image data portion. When a pixel value is “partially on” (i.e., between “fully on” and “fully off”), the light modulating elements of the associated group are configured such that modulating elements located in the center of each group are activated, and elements located on the upper and lower ends of each group are deactivated.

  • Patent number: 8363280
    Abstract: Systems and methods of halftoning an image for extended-colorant printing image spot colors are provided which perform a quality ranking of a plurality of periodic halftone screens to be used in halftoning the image and an objectionability ranking of the colorants used to produce the one or more image spot colors. Halftone screen-to-colorant assignments are then made using a ranked ordered pairing of the ranked screens and ranked colorants. The image is halftoned using these assignments and the results can be printed or saved for future printing. Pixel tags can be used to identify the ranked ordered halftone screen-to-colorant assignments.

  • Patent number: 8351084
    Abstract: 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.
