Abstract: What is provided herein is a novel system and method for estimating the amount of color in a document. In one embodiment, a binary CMYK input image is received. Each of the CMYK plane is received at an offset from the previous plane, i.e., the 4 planes are not received simultaneously. Each plane is divided into M×N tiles. Pixel values of all four planes are examined separately and the number of on-pixels is counted for each plane. The number of on-pixel counts for each tile are aggregated for each plane. Total on-pixel counts are used to estimate the total number of white, black, color, and gray pixel counts. The total counts for all planes are used to estimate the amount of color. A document is determined to be color if the amount of color exceeds a predetermined threshold. A color billing strategy is determined based on the estimated color amount.

Abstract: What is provided are a novel system, method, and computer program product for estimating the amount of color in a document to be printed, with the capability to handle composite black. A color billing strategy can be dynamically determined based on the amount of color in the document. In one embodiment, a contone CMYK image is examined and the level of color is estimated based on information extracted from the four planes simultaneously. More specifically, it examines the pixel values from all the four planes to calculate the number of white, black, color, and gray or neutral pixel counts. Input CMYK values can be pre-adjusted via a look-up table to take into account neutral balance characteristics. The difference among the adjusted color values is compared against a threshold that is input level dependent. Color is further subdivided into fuzzy colors to handle highlights and neutral areas.

Abstract: Methods and systems for performing resolution expansion with high quality edge enhancement capability utilizing an edge detector and a color estimator. An edge tag with respect to an input image can be detected via an edge detector and an edge detection approach. A resolution expansion can be separately applied to the edge tag and a binary output generated by other processing functions. Multiple output lines corresponding to the input image from the color estimator with different threshold array values for an edge pixel can be generated by a halftoning module. A binary domain resolution expansion can be applied for a non-edge pixel. A final output for each pixel can be selected from a resolution expanded result and/or from the result of the halftoning for the edge based on the edge tag with respect to that pixel.

Abstract: What is disclosed is a system and method for determining an orientation direction of a color edge at a given pixel location in a binary color image. The orientation direction of the color edge is determined from eight pixel counts with each pixel count being a total number of pixels in each of eight regions of a window centered about a candidate pixel which resides along the color edge. The eight regions are associated with 8 compass points. The orientation of the edge is determined by a 1st, 2nd and 3rd tier control bits which are based upon the pixel counts of each region. The 1st, 2nd and 3rd tier control bits collectively form a 3-bit word. The 3-bit word defines the orientation direction. The teachings hereof provide an efficient way of performing binary edge orientation detection by making uses of intermediate results to simultaneously encode the edge orientation.
