摘要： A method for determining a confidence level to be used in identifying a vehicle. The method includes receiving a vehicle image, extracting a license plate image from the at least one vehicle image, determining a license plate number and associated confidence level based upon the license plate image, and comparing the associated confidence level against a confidence threshold. If the associated confidence level is below the confidence threshold, the method further includes extracting auxiliary data from the at least one vehicle image, corresponding the extracted auxiliary data and a set of stored auxiliary data, and updating the associated confidence level to produce an updated confidence level based upon the correspondence of the extracted auxiliary data and the set of stored auxiliary data.

摘要： Streak compensation in a digital printer is provided utilizing a spatially varying Printer Model and Run Time updates to generate Spatially Varying Tone Reproduction Curves (STRCs) which are used as actuators to compensate for streaks during run time. A full width array sensor is used to measure streak profiles and the STRCs are used as actuators to compensate for streaks. Streak profile measurements taken at a limited number of area coverage levels combined with a Printer Streaks Basis Function Model are used to estimate and project the streak behavior at all area coverage levels and at all inboard-to-outboard spatial locations. The projection is then used in a pixel-wise error feedback control scheme to drive each profile to a desired shape, thereby compensating for streaks.

摘要： Systems and methods are provided for compensating for streak defects in images formed by an image forming device, such as a digital printer. The methods include using a spatially varying printer model and run time updates to generate spatially varying tone reproduction curves (STRC actuation) in an iterative control system for improving streak correction in a digital printing machine. Streaks are rapidly learned and eliminated at cycle-up and tracked and eliminated during print run time using STRC actuation.

摘要： A control system for use with a development process including at least one magnetic roll with a settable speed is provided. The controller is directly or indirectly responsive to a reload feedback signal, which signal is generated in response to changes in output reload performance of the development process. In the case of direct responsiveness, the controller uses one or more reload feedback signals to facilitate magnetic roll speed setting. In the case of indirect responsiveness, the controller uses a reload sensitivity signal, which reload sensitivity signal varies as a function of input digital image content and output reload performance feedback, to facilitate magnetic roll speed setting.

摘要： A defect analysis system for a xerographic print engine includes a residual mass sensor that senses the two-dimensional signature structure of residual mass remaining on a photoconductive or other substrate surface after image transfer. Preferably, the sensor is a full width array that spans substantially an entire width of the photoconductive surface. This information is then processed and analyzed to determine a specific type of transfer defect present. This may include the quantified level of defect for each detected type. The defect analysis system may also include a closed-loop control system that can adjust various xerographic process parameters using feedback based on the identification and optionally magnitude of each specific defect type. The identified print quality defect, such as mottle, streaks, point deletions, graininess, etc. can then be used to determine a customized corrective control action to be taken by the feedback control of the xerographic print engine to remedy or compensate for the defect(s).

摘要： Multiple input patches are received on an output media, which patches are characterized by print density representing a document processing system's response to different input grayscale values over a potential response space. Values associated with the print density of each input grayscale value are measured. Reference Engine Response Curves are determined from the measured print density values and input gray scale values. A variance data representative of a difference between each measured print density value and a respective reference Engine Response Curve is determined. The variance data is transformed into individual components. Based at least on one selected individual component, a set of calibration compensating Tone Reproduction Curves is determined. The determined calibration compensating Tone Reproduction Curves are applied to input grayscale values.

摘要： Systems and method provide compensation for temperature induced peak wavelength shift of LEDs is color parameter measuring systems that use a model to reconstruct target color parameter values from the reflectance values measured when the target is illuminated by LEDs. Several models may be constructed, with each model being trained at a unique temperature, resulting in a set of models that span the temperature range of interest. In real-time, the LED based color parameter measuring system measures the temperature and interpolates between the models to estimate the appropriate model to use at the temperature of interest. The estimated model is then used to perform the color parameter value estimation.

摘要： Systems and methods of marking control achieve improved image quality in a multipass marking process by taking into account positioning errors that have already occurred in prior marking passes while building the image, and compensates for them in real-time by modifying the remaining interlace locations of the marking subsystem in order to minimize predicted image quality defect perception in the resultant image. The adjustment are preferably based on minimizing a defect perceivability metric. One such suitable metric is a frequency metric, preferably the power spectral density of the resultant image evaluated at the fundamental frequency (1/D), where D represents the spacing of marking devices, such as the spacing of print head nozzles.
