ABSTRACT:
A method for enhancing reproduction of pixel images includes the steps of: storing a raster scan bit map of an image; selecting an input window from the bit map image that includes a plurality of row segments of bits representing pixels, the input window having a center pixel bit; comparing a subset of bits in the input window (that includes the center pixel bit) with a plurality of prediction bit subsets, each prediction subset represented in a plurality of rotation orientations, and upon finding a match with one of the prediction bit subsets, rotating the input window to the degree and direction indicated by a command associated with a matching prediction subset (if any); comparing the rotated input window with a limited set of sample windows to determine a match of certain bit states within the rotated input window with certain bits of a stored sample window; and upon determining that such a match exists, substituting an enhanced pixel representation for the center pixel bit of the input window.
