Abstract
Pixels in a grayscale image are identified for coalescing based on a corresponding value in a threshold matrix. This threshold matrix value is then used to determine both the color and number of pixels to be coalesced at this location. Grayscale pixels are then coalesced based on pixels which will ultimately be the same color as the identified pixel. The coalesced grayscale image is then compared on a pixel-by-pixel basis to corresponding values in the threshold matrix to determine a halftone image.
