Abstract
Method and apparatus for locating dot-matrix printed text in a digital image and filtering only those regions determined to contain dot-matrix printed text. The apparatus incorporates a detection algorithm with a digital filter. The system detects dot-matrix printed text and selectively turns the filter on or off within regions of the digital image, thereby improving read rates of dot-matrix printed text while not affecting read rates of higher quality machine printed text.
