<p>A small hand-held scanner (12) that scans text in a line at a time operates in conjunction with a system that deskews images of symbols having a non-linear baseline to thereby flatten waviness of the baseline associated with such scanning. A program determines a boundary for each of the symbols (310). Any of the average height, average width, maximum height, maximum width, and average change in height of a bottom of each symbol relative to that of a neighboring symbol is also determined (330). A threshold is used to delineate between a change of the baseline that is due to random hand movement versus a change in the baseline that is due to a descender (360), where the descender generates a greater change, and all of the symbols that are to be on the baseline are shifted to a single flat baseline (370).</p> |
