ABSTRACT:
A bi-level image is pre-processed by dividing the image into rectangular blocks, and rearranging the dots in each rectangular block into a pattern determined by the density of black dots in the block. The resulting rearranged image is suitable for further processing such as resolution conversion or compressive encoding.
