Abstract

A method of converting a scanned image comprising scanned pixels to a corresponding bitmap image, said method comprising the steps of, for each bit in the bitmap image; a. determining an expected location in said scanned image of a current bit from the location of surrounding bits in said scanned image; b. determining a likely value of said bit from the values at the locations of expected corresponding pixels in said scanned image; c. determining a centroid measures of the centre of the centre of the expected intensity at the said expected location; d. determining similar centroid measures for adjacent pixels surrounding said current bit in said scanned image and; e. where said centroid measure is improved relative to said expected location, adjusting said expected location to be an adjacent pixel having an improved centroid measure.
