Abstract: The present disclosure relates to a method and system for processing isolated dots of an image to be printed by a printer. The method includes detecting whether pixels corresponding to an isolated dot in the image are in an on state. A first sum of pixels that are in an on state in a first pixel ring surrounding the pixels corresponding to the isolated dot when the pixels in the isolated dot are detected to be in the on state is determined. The first sum of pixels in the first pixel ring that are in the on state is compared with a first threshold sum. A first number of pixels in at least a second pixel ring either comprising of or surrounding the pixels corresponding to the isolated dot are turned on when the first sum of pixels in the on state is less than the first threshold sum.

Abstract: Embodiments relate to systems and methods for dynamic sharpness control in system using binary to continuous tone conversion. Image data can be processed in the image path of a copier, printer, or other device to enhance sharpness based on user settings. The image can originate in a high-resolution and/or high-color format. The user can select sharpness values to provide better rendered detail. A front-end high-pass 2D filter can be adjusted in response to the settings. A binarized version of the image data is produced in the downstream path. At the back of the image path, the image would conventionally be sent through a binary data to extended contone (BDEC) low-pass filter, set to a fixed level, to produce contone output, counteracting the user's sharpness settings. Instead of applying a fixed back-end filter, that stage can be dynamically adjusted to correspond to the user's sharpness settings, reducing the low-pass effect proportionately.

Abstract: Disclosed herein are a method and a system implementing the method for billing using color pixel counting in documents or image in the contone domain. The method includes using the intensity or density levels (e.g., 0 to 255) for each color of each pixel of interest in the contone domain to calculate one or more probability values that one or more output colorants are provided at its location in the binary domain. The probabilities determined based on the contone color domain data are used to estimate an overall area coverage of color pixels in the document, which can be used to determine a billing structure or cost for outputting the document.

Abstract: Disclosed is a processor-implemented method for processing image data of a document using an apparatus. The processor determines pixel classifications and counts for each classification, classifies the image, selects a billing tier for which to bill the image, determines counts of pixels for marking to output the image (e.g., in device dependent space), and then can adjust from the selected billing tier to a different billing tier based on the image classification (e.g., and/or using determined counts of pixels for each classification and determined counts of pixels for marking). Counts of pixels can be adjusted using an offset, or calculated using a combination of the determined counts (e.g., combining counts from both independent and dependent spaces). By adjusting the tier at which to bill data, more accurate billing can be implemented for documents with contone or grayscale image data, for example, with greater customer satisfaction.

Abstract: A system and method for pixel and object level neutral detection. An image is scanned into a plurality of pixels. A local pixel of interest is identified along with a neighborhood of pixels around the local pixel. The chroma value of the current pixel as well as the average local chroma of the neighborhood are calculated. An adjusted chroma is determined based on the average local chroma. A luminance value can also be measured for the current pixel and for each of the neighbor pixels and a luminance variation determined. The adjusted chroma can be further modified based on the determined luminance variation. The adjusted chroma is compared against a threshold to determine a neutral pixel detection tag for the current pixel. The pixel tags can be utilized to control an adjustment of pixels in a device independent L*a*b* or a device independent CMYK domain.
