SYSTEM AND PROCESS FOR REMOVING A BACKGROUND PATTERN FROM A BINARY IMAGE

A system is provided for removing a background pattern from a binary image. The system comprises a device for storing the binary image, and a processing device. The processing device may perform various steps, including (1) dividing the binary image stored in the storage device into a plurality of stored image regions, (2) for each of the plurality of stored image regions, calculating the image density value associated with such stored image region, (3) counting the number of stored image regions associated with each image density value, (4) identifying the image density values having the maximum number of associated stored image regions, (5) selecting as a threshold density value a less dense value from the identified image density values, and (6) for each stored image region stored in the storage device having a density value less than the threshold density value, resetting the stored image region to a zero value.
