Claim One:
1. An image processing system comprising: means for storing a binary bitmap image file including a plurality of pixel locations; means for determining a gradient magnitude corresponding to each pixel location of the binary bitmap image file; means for determining a gradient direction corresponding to each pixel location of the binary bitmap image file; decision matrix means for comparing a window of the binary bitmap image file and the gradient magnitudes and directions corresponding thereto to predetermined templates and generating a look-up-table address if a match occurs; a look-up-table for generating enhanced gray-scale image data in response to the look-up-table address and wherein the decision matrix means determines whether a central pixel of the window is a black or white pixel, whether the central pixel is located in a single pixel width line, and the location of the central pixel with respect to a kink site.
