One of the most widely used steps in the process of reducing images to information is segmentation, which divides the image into regions that hopefully correspond to structural units in the scene or distinguish objects of interest. Segmentation is often described by analogy to visual processes as a foreground/background separation, implying that the selection procedure concentrates on a single kind of feature and discards the rest. Machine-printed or hand-drawn scripts can have various font types or writing styles. The writing styles can be roughly categorized into discrete style (handprint or boxed style), continuous style (cursive style), and mixed style. We can see that the ambiguity of character segmentation has three major sources: (1) variability of character size and inter character space; (2) confusion between inter character and within-character space; and (3) touching between characters.
