摘要： What is disclosed is a novel system and method for updating a cluster model for color control. In one example embodiment, a cluster model is received and analyzed to identify clusters therein. Each of the identified clusters has an associated transform. Thereafter, in response to a threshold event having occurred, a critical cluster is identified and a critical color is identified from the cluster. Steps for identifying a critical color are more fully described herein. A selected number of patches is then printed in each of the critical colors and color measurements are obtained from the printed patches using, for instance, a colorimeter or spectrophotometer. If the color measurements have deviated beyond a defined threshold, then update the cluster model by: updating the transform associated with the cluster; redefining the number of clusters; redefining a center of any of the clusters; or redefining a boundary of the clusters.

摘要： What is disclosed is a novel system and method for determining the number of persons in an IR image obtained using an IR imaging system. The present method separates a human from the surrounding background via a set of particularly formed intensity ratios. Quantities derived from these ratios and threshold values are used to selectively classify whether a pixel in the IR image is from a human or from a non-human. Based upon the classification of the various pixels in the IR image, the number of persons is determined. Various embodiments are disclosed.

摘要： What is disclosed is a novel system and method for xerographic Dmax control based upon measurements made on the printed paper using an inline spectrophotometer (ILS) or similar device. The disclosed method is based upon directly measuring the color to actuator sensitivity. Each of the separations is controlled independently using an actuator specific to that color separation. The present method is effective at controlling the color of the solid primaries. The fact that the vector of change is highly correlated with solid color variation seen in the field suggests that the teachings hereof effectively increase the solid color stability. Increased solid color stability increases the color stability throughout the printer gamut and the stability of the gamut boundaries, which increases the robustness of gamut mapping algorithms. Advantageously, the present method can be combined with existing ILS-based maintenance architectures.

摘要： What is disclosed is a novel system and method to reduce noise induced by color mixing in a color management system. At least one device color recipe is obtained for a target spot color. The recipe is defined for a color marking device and defines a range of marking device color values for a target L*a*b color value. Next, a minimal value and a maximum value of each color value in the range of color values for said target L*a*b color value are identified. An iterative process of searching is performed until the printed color test patch produces a visually acceptable smoothness while matching color accuracy. This iterative process includes generating at least one additional new device color recipe from color values within the range of color values. At least one of the new device color recipes is selected and provided to the color marking device for rendering.

摘要： A method and system of color management for an image marking device. A sensor measures printed hardcopy colors. A first gain, computed by a linear controller based on a linear model, is scheduled for each color node of a sampled color space. For each node where a convergence error exceeds a threshold, a second gain is scheduled by a nonlinear controller. The second gain scheduling includes initializing operational parameters, and performing an iterative procedure. The iterative procedure includes computing gain matrices over a defined projection horizon, evaluating a cost function for each gain matrix, determining the cost function, scheduling a new gain based on selecting a gain matrix having the minimum value of the cost function, and computing new CMYK values based on the new gain. A multidimensional LUT based on the scheduled gain matrices is generated and stored in memory, and a hardcopy output image is generated based on the stored multidimensional LUT.

摘要： What is disclosed is a novel system and method for characterizing a model-based spectral reflectance sensing device. In accordance with the teachings hereof, measurements of training samples taken with a previously manufactured ‘fleet master’ sensing device are adapted, in a manner more fully disclosed herein, based upon knowledge of the wavelengths of the illuminators used for both the subject and fleet master sensors, as well as spectral reflectance response of the training samples as measured by a reference spectrophotometer device. Utilizing the adapted measurements of the fleet master device, a reconstruction matrix can be quickly constructed for the subject sensor. The present system and method provides reasonably good accuracy using pre-existing measurement data. This results in manufacturing cost savings on a per-sensor basis.

摘要： A computerized system, method, and software apparatus is presented which reduces the black level of the printing process in order to substantially remove stray black dots from the finished product of a printing output. Black levels are reduced by updating the print engine regions for the colors W, C, M, Y, MY, CM, CY, and neutral and by assigning a weights each color. The values are used to compute CMKY values. These values are then placed in a gain matrix and stored in a computer memory.
