Abstract: What is disclosed is a novel system and method for calculating an amount of a total dilation for reverse objects in order to compensate for fill-in effects to improve quality of a digital image in a digital document reproduction system. In a manner more fully described herein, a tone-dependent compensation factor is determined which is a function of a gamma-corrected background density. The tone-dependent compensation factor is then used to scale the maximum base dilation to produce an amount of total dilation. The total dilation amount is applied to contone pixels along an edge of the reverse object to compensate for fill-in artifact effects. By adjusting pixels along the edges of reverse objects by the total dilation determined hereby, the sharpness (or crispness) of reverse fine features is improved on sweeps and for hue shifts at the edges of the reverse objects on backgrounds of more than one color separation.

Abstract: Systems and methods are described that facilitate calibrating a print engine using calibration data sets generated at at least two different L* levels to provide additional calibration measurement resolution toward the darker end of the grayscale spectrum. For instance a first, light grey (e.g., 70-90L*) calibration strip is scanned at a first resolution (e.g., 70-90L*) to generate a first calibration data set, and a second darker grey (e.g., 30-50L*) calibration strip is scanned at high resolution (e.g., 100L*) to generate a second calibration data set. The first calibration data set is used to calibrate the print engine for high L* values (e.g., 50-100) and the second calibration data set is used to calibrate the print engine for low L* values (e.g., 0-50). Alternatively, a single calibration strip having a known L* value can be scanned once at the known L* value and again at a higher L* value (e.g.

Abstract: A computer program product and method for calibrating and characterizing a color display perform calibrating and characterizing steps. A light source is operated in order to emit light from one or more light emitters on the light source. A color capture device, e.g., a digital camera, is calibrated and characterized based on the emitted light. Then, color images are displayed on the color display and captured on the color capture device. The color display is calibrated and characterized based on the captured color images. Computer program instructions are recorded on the computer readable medium, and are executable by a processor, for performing the calibrating and characterizing steps. A method for generating a controlled light source includes displaying light source selections to a user and receiving a user light source selection. Selected light emitters produce a light output matching the user light source selection.

Abstract: What is provided herein is a method for automatically selecting a subset of pages from a multi-page document for image processing wherein each selected page is substantially different from all other pages according to certain features of interest and wherein the combined content of the selected pages approximately represents the content in the entire document. Selected pages are clustered wherein each page is represented by a feature vector meaningfully related to the task to be performed. A matrix of feature vectors is analyzed. Basis vectors are extracted from the matrix using rank-reduction techniques. Clustering is performed by subspace projection of page features onto the basis vectors with each page being assigned to a cluster to which that page maximally projects. Representative pages are selected from each cluster. The representative pages can then be used as input to a secondary process.
