Abstract:
1. An image processing apparatus comprising: a thinning process unit which extracts a core line by applying a thinning process to an input image; a line width estimation unit which estimates an original line width of each pixel of the core line extracted by said thinning process unit; a core line division unit which divides the core line extracted by said thinning process unit at an intersection; a monospaced line determination unit which determines, based on line width information estimated by said line width estimation unit, whether or not each of core lines divided by said core line division unit is a monospaced line; a connection relation information generation unit which generates connection relation information with another core line in association with each of the core lines divided by said core line division unit; and a core line modification unit which modifies the core lines divided by said core line division unit, based on pieces of line width information of core line pixels estimated by said line width estimation unit, a monospaced line determination result by said monospaced line determination unit, and pieces of connection relation information generated by said connection relation information generation unit.
