摘要： 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.

摘要： 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.

摘要： A methodology for thin line detection and enhancement in electronic images is disclosed. The methodology includes associating an electronic image with at least one basic context window that is less than the size of the electronic image based on the input image resolution of the electronic image; detecting one or more predefined patterns which correspond to thin lines in the electronic image using the at least one basic context window; excluding patterns for the one or more detected patterns which are halftone patterns; and adding at least one pixel to the electronic image based on at least one of the remaining patterns so as to enhance thin line features in the electronic image. In some implementation, the methodology may be configured to handle electronic images having different resolutions. A system for thin line detection and enhancement in electronic images having different resolutions is also disclosed.
