摘要： A method, system, and computer-usable tangible storage device for traffic camera diagnostics via strategic use of moving test targets are disclosed. The disclosed embodiments can comprise four modules: Moving test target management module, Moving test target detection and identification module, Image/video feature extraction module, and Sensor characterization and diagnostics module. A first test vehicle can travel periodically through traffic camera(s) of interest. The traffic camera(s) would then identify these test vehicles via matching of license plate numbers and then identify test targets in video frames through pattern matching or barcode reading. The identified test targets are then analyzed to extract image and video features that can be used for sensor characterization, sensor health assessment, and sensor diagnostics. The disclosed embodiments provide for a non-traffic-stop (i.e., non-traffic-interruption) traffic camera diagnostics.

摘要： Embodiments are disclosed for generating an infrared mark indicator comprised of security information in a printed image. Image data is rendered to a CMYK image. A black plane of the CMYK image is separated and transformed to a frequency domain wherein the frequency components are alternated to encode the watermarking message. The CMY values are selected based on the encoded black value in order to maintain a same color appearance image for the printed image under a normal visual light illuminant. The image data is printed on the substrate in accordance with the transformed planes wherein upon the resultant printed image being exposed to infrared illuminant, a print pattern is detectable as an infrared mark when scanned with an infrared sensing device.

摘要： An imaging system for forming multiple image exposure frames on a photoconductive member moving in a process direction including a raster output scanner forming a plurality of scanlines in a transverse direction across the width of the member by reflecting modulated beams from a plurality of facets of a rotating polygon. Hall effect magnetic sensors mounted with respect to a motor driving the polygon provide a first speed control of the polygon with the laser in a not ready or an off state and start of scan signals detecting the beginning of a scan line provide a second speed control of the polygon with the laser in an on or ready state. Circuitry or control code responds to the SOS signals and the magnetic sensors to dynamically switch between the first speed control and the second speed control.

摘要： An image watermarking method includes a color transform on RGB image data to derive CMYK image data that define a constant K image. Variable infrared (IR) mark data defining an IR mark are received and a sparse two-dimensional pattern of black pixels is defined that corresponds to the variable IR data, e.g., using Gold codes or pseudorandom binary sequences. A watermarked black separation K″ is defined by embedding the sparse two-dimensional pattern into the constant K black separation K′ while maintaining local average levels. A watermarked image includes the watermarked black separation K″ in combination with the CMY separations of the constant K image. A decoding process includes using an IR microscope fitted with IR LEDs and an IR pass filter to capture an IR image, which is subjected to exposure correction, thresholding, and dilation operations to extract the two-dimensional pattern for subsequent correlation processing.

摘要： 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.

摘要： A reflex printing device having multiple print heads mounted at different locations around the circumference of the drum at different “angles” and an encoder disk mounted on the drum to allow for detection of the drum position as a function of time. An image defect due to a misalignment in the print process direction of the output from the multiple print heads is corrected by detection of an encoder position error function subtracted from itself shifted by the angle between the print heads.

摘要： A simplified system for sensing the movement and/or position on both axes of a moving surface, such as a photoreceptor belt of a xerographic printer, or a sheet transport of an ink jet printer, utilizing a linear track of small and closely spaced “Z” shaped marks on or in a moving belt or roller surface. These marks are used to accurately incrementally directly detect surface motions in both orthogonal axes with a co-linear optical sensor linear array of a multiplicity of individual pixel optical detectors which respectively detect and compare the changes in positions relative thereto of the transverse and angled lines of those Z marks during frequent short measurement intervals. This exemplary system provides direct, and thus more accurate, surface movement measurement information, with much less critical and less costly marking requirements, and greater tolerance for variations in the subject surface, as compared to indirect or conventional encoder type positional sensors.
