Isolated noise from an image appearing as black spots in white areas and voids in black areas is removed to improve image
quality. Common noise includes toner and fax particles. Noise reduction works via an algorithm that removes pixels up to 5 x 5

pixels.
O

shape of the characters are recognized by the differences in the light reflected off the documents.
