    Abstract: In one form, the method comprises obtaining scanned values of the image, scaling the scanned values to obtain scaled values, applying a non-linear correction function to the scaled values to obtain a first approximation of corrected reflectance values, filtering the corrected reflectance values by applying a piecewise Gaussian filter, applying the non-linear correction function to obtain a successive approximation of the corrected reflectance values, determining whether the successive approximation of the corrected reflectance values are sufficiently converged, selectively repeating the filtering and applying if the corrected reflectance values are insufficiently converged and selecting the corrected reflectance values for subsequent processing if the corrected reflectance values are sufficiently converged.

    Abstract: A system using a spatial correction to improve the result of a printer calibration and correction is described. More particularly, in one form, a spatial correction may be used to pre-condition a printer for an improved color calibration.

    Abstract: In an exemplary embodiment, a method is employed to read an overprinted barcode. An RGB pixel map is obtained from an overprinted color barcode that contains a plurality of disparate colors. A pixel map is allocated for each of the colors detected and each pixel is classified in the one or more pixel maps according to color. One or more barcodes are extracted from the overprinted barcode that correlates to each color detected. Each of the extracted barcodes are then filtered, decoded and read.

    Abstract: Systems and methods are described that facilitate improving error estimation for calibration error due to clipping of pixels, and compensation therefor, during calibration of a scanner or printer. Calibration patches are measured at a first maximum pixel value threshold and at a slightly lower threshold value. Pixel values for the patches at each threshold are averaged, and a linear model is constructed, which is employed to predict error due to pixel clipping. The error is then compensated for when calibrating the scanner or printer.

    Abstract: A method for identifying and correcting for spatial variation within scanning bars includes performing diagnostic scans of at least one sheet, in which a sheet(s) is scanned in various orientations and translations, with each of the orientations identified. The diagnostic scans are registered with one of the individual diagnostic scans to produce registered scans. The registered scans are averaged to create a master scan corresponding to the sheet, such that the master scan is indicative of the spatial variation within the sheet.

    Abstract: Systems and methods are described that facilitate calibrating a scanner by capturing a plurality of white calibration files and generating a mathematical function that models the scanner. For instance, a white calibration file can be captured before and after a page is scanned, and the function can be an average of offset and gain values for pixels in scanlines of the scanned page. Three or more white calibration files can be used to generate a linear function (e.g., using linear regression) or an exponential function describing the gain an offset values of the pixels.

    Abstract: A method for encoding information on a printed page includes generating a set of color patches, each having a unique color. The set of color patches is printed. The printed color patches are scanned to identify color values for each patch in the set of patches. For each patch, the identified color values are associated with a datum value in a data structure. A page which includes a patch code is printed. The patch code includes selected ones of the set of color patches for conveying information about the printed page. The printed page is scanned to identify the color values for the color patches in the patch code. The data structure is accessed to identify the data values for the identified color values of the patches in the patch code. Information about the printed page is determined from the identified data values.
