Methods and systems herein provide for color conversion. Such color conversion includes gamut mapping by determining a color gamut of an imaging device and receiving color data having color values external to the color gamut of the imaging device. The gamut mapping proceeds by determining a color region external to the color gamut and mapping the color values within the color region to the color gamut. Thereafter, the area of the color region is increased and the color values within the increased color region are mapped to the color gamut.

A system and method for managing image storage size. The invention uses reduction criteria to determine how much to reduce the storage size of an image over time. In one embodiment, reduction of data storage size includes degrading the quality of the image. The reduced-size image replaces the image from the previous iteration. The smaller storage allows longer access to the information in quick access storage and quicker transmission time.

Managing image storage size

Methods and systems herein provide for color conversion in the real domain from an input color space to an output color space using a color conversion table that includes color values defined in the output color space corresponding to color values in the input color space, a table of scaling factors, and a conversion engine operable to group the real domain image data into blocks of pixels. The conversion engine, for each block of pixels, converts a color value in the block of pixels from the input color space to the output color space according to the color conversion table, computes differences between the color value and color values of pixels in the block, scales the computed differences according to the table of scaling factors, and adds the scaled differences to the converted color values to convert the pixel color values to the output color space.

Dynamic test coverage to evaluate an artifact code is provided. Code of an artifact to be tested is identified. The code coverage of the test code is analyzed. The current coverage information is stored. Code coverage information for one or more prior versions of the test code is retrieved. The current coverage information is compared with the prior coverage information. Responsive to a determination that a difference between the current coverage information and the prior coverage information exists, the difference is collected. Responsive to a determination that test cases are to be generated automatically, generating, automatically, new test cases based on the difference. The new test cases are stored. Code coverage of the test code is analyzed based on the new test case. The new coverage information is stored. The new coverage information is sent to the user.

Dynamic test coverage

A printing system is disclosed. The printing system includes an image processor to rasterize a received print job and to perform a halftone by comparing a first threshold value from a threshold matrix to a first image component sample, comparing the first threshold value to a first number of sequential image component samples neighboring the first sample if the first threshold value is less than the first sample and comparing the first threshold value to a second number of sequential image component samples neighboring the first sample if the first threshold value is greater than or equal to the first sample.

Methods and apparatus for user customization of flush patterns in an ink-based printing system. Features and aspects hereof provide for user input to define a flush pattern and to define a location at which the flush pattern is to be placed on sheetside images. By integrating the flush pattern as defined by the user into the sheetside images, the flush pattern may convey useful information or may at least be aesthetically acceptable as compared to prior flush pattern definitions. The user may select among a plurality of standard, pre-defined patterns and locations or may define a fully customized pattern to be placed at a fully customized location. Text or other potentially useful patterns may be defined by the user. Analysis of the sheetside images may permit the user to define placement of the pattern so as to avoid occluding information imprinted on the sheetside images.

A computer implemented method, data processing system, and computer program product for managing multilevel hierarchical structured information in disparate knowledge repositories. An association data structure is created for an entity as metadata in a metadata repository. The association data structure is populated with association information about the entity. A process data structure is created for the entity as metadata in the metadata repository. The process data structure is populated with process information about the entity. Information about a multi-phased process is then collected by extracting process information from each entity of the multi-phased process across the disparate knowledge repositories. The collected information comprising information about the multi-phased process is then stored in the process data structure in the metadata repository.

Multilevel hierarchical associations between entities in a knowledge system

Systems and methods of printing to a tangible medium provide for reducing ink penetration via the controlled selection of halftone patterns. One method includes steps of printing to the tangible medium (e.g., via a multicolor ink supply such as CMYK) using a plurality of initial halftone patterns, measuring ink absorption of the tangible medium in response to printing to the tangible medium, and determining a subset of the plurality of initial halftone patterns based on the absorption measurement. The method also includes printing a print job to the tangible medium based on the subset of the plurality of initial halftone patterns. For example, a print controller may be reprogrammed with the subset of the plurality of initial halftone patterns to print a print job to reduce the amount of ink applied to the tangible medium.

Printing with alternative halftone patterns in ink jet printing to reduce ink penetration

An ink jet printing system includes a first print system having a first ink system to print received print jobs, a second print system having a second ink system independent of the first ink system to print the print jobs and a control unit to receive the print jobs and determine which of the first and second print systems is to print each received print job.

Computation of variance or variance of the autocorrelation over a moving window of various sizes of a signal containing noise and possibly a small digital signal provides a sensitive, frequency independent indication of the likelihood of the presence of a small pulse, chirp or even spread spectrum digital signal possibly obscured by noise or larger signals in the signal to much lower signal-to-noise ratios than previously possible. Large signals in the signal which may also obscure any small signal are removed to a different signal path from the noise and small signals by subtraction after compression and reconstruction of the large signal. The compression noise thus added to the signal may also increase sensitivity of the variance of the autocorrelation to small signals obscured by the large signals. Controlling storage in response to the computed variance or variance of the autocorrelation allows substantial avoidance or limitation of storage of signals which contain only noise.

Using statistics to locate signals in noise

A halftone threshold matrix includes a plurality of submatrices, wherein a first group of the plurality of submatrices has a line screen frequency different from a second group of the plurality of submatrices. The halftone method and apparatus removes the restriction that at most one pel is turned on per basic cell for the next constant input level and allows the pels in some basic cells to be turned on much sooner that the corresponding positions in other basic cells. This creates a dominant low frequency line screen simultaneously with the higher frequency line screen of the other basic cells. The present invention also allows the basic cells inside the threshold matrix to have different shapes and sizes. Thus, the cells participating in the low frequency screen could be larger than the cells generating the higher frequency screen. For example, the low frequency screen's pleasing patterns can distract the eye from noticing less pleasing patterns in the high frequency grid and vice versa.
