ABSTRACT:
In brief, a method of reducing an M X N input binary image (M rows of N pixels each) by a factor of m vertically and n horizontally includes the steps of performing at least one logical operation between bits in consecutive groups of m adjacent rows to provide a resultant single row for each group of m rows, and performing at least one logical operation between bits in consecutive groups of n adjacent columns to provide a resultant single column for each groups of n columns. For certain types of reductions, the resulting reduced image will be the desired output image, while for other types, the resultant image will be one of a required plurality of intermediate images, which are then combined to provide the desired output image.
