Abstract
A computer-implemented method of highlighting text regions within a first scan line signal including image regions. Text/image segmentation begins by identifying a set of edges of a possible text region within the scan line signal. Next, without reference to a second scan line signal, it is determined whether the set of edges of the possible text region first form a text region. If the set of edges form a text region, then the average pel intensity value of the text region is calculated. Afterward, the intensity values of those pels within the text region whose values differ from the average are modified.
