Abstract: A method of and system for calibrating an imaging device is described herein. An iterative method that attempts to find the best calibration parameters conditional upon an error metric is used. Regression is used to estimate values in a color space where the calibration is performed based upon a training data set. More calculation steps are required than would be for a regression in raw RGB space, but the convergence is faster in the color space where the calibration is performed, and the advantages using boundary conditions in the color space is able to provide improved calibration.

Abstract: A system and method for effectively implementing a dither matrix for an electronic printer device may preferably create an improved dither matrix with optimal threshold values for use in a corresponding dither tile. During a matrix populating procedure for assigning tile threshold values for the dither matrix, the dither tile may preferably be embedded within a larger frame area of additional adjacent frame cells. A design entity may then preferably compute various cost functions when the additional boundary cells of the frame area are in place. The embedded dither matrix of the dither tile is thus preferably populated within the foregoing frame area so that various boundary effects may be taken into account when an overall cost function of both the dither tile plus the frame area is calculated.

Abstract: A system and method for gray-scale or color printing is disclosed. One embodiment of the present invention transposes multiple pairs of pixels at the same time. During this process a record of the values of the cost function is kept. After a good statistical sample of multiple pairs of pixel replacements has occurred, the top five combinations are then selected for further refinement. During this next round of calculations the multiple of pairs of pixels transposed is reduced by a factor of two. In another embodiment of the present invention, the selection of the groups of pixels to transpose is controlled. During the initial iteration stages, a minimal radial offset of separation is imposed upon the pixel selection. Typically this minimum radial offset starts at one quarter of the array height. This selection process ensures that transpositions have the largest mixture around the array.

Abstract: A system for and method of determining calibration parameters while only capturing a single image is described herein. Furthermore, traditional calibration algorithms are avoided by the direct determination of the calibration parameters. The determination of the calibration parameters is possible by first determining a training data set from images acquired of a variety of objects with a multitude of colors. Then, using the training data set, regression coefficients are generated. A camera to be calibrated then acquires only one set of image information such as a single picture. Then, using the regression coefficients and the acquired information, the calibration parameters are directly estimated for that camera.

Abstract: Digital images often have undesired color casts due to unusual illuminant sources. A color correction method is provided that uses adaptive segmentation to identify the presence of such casts, estimate their chromatic strength, and alter the image's near-neutral-color regions to compensate for the cast. The method identifies most major objects in a scene and their average color. A color space having an achromatic axis is provided with a default gray radius that is used for establishing bins of neutral color in a chromatic plane. The bins are populated with the pixels of the digital color image based on pixel chromaticity. A color histogram computed with chromaticity peaks for the pixels in the bins within the default gray radius. The default gray radius is adjusted to a gray radius based on the chromaticity peaks in the color histogram. The color cast is detected from a dominant chromaticity peak, or two chromatic peaks in the same chromatic quadrant, within the gray radius and color cast distance from the distance thereof from the achromatic axis. The color cast is removed from the pixels by subtracting the color cast distance from the color image in the color space and outputting a color cast removed color image.
