IPC: G06K9/46
Filed: 1989-04-24
Abstract: PURPOSE:To facilitate the identification of a character being similar in other part than left-and-right shapes by deriving the left and right reference lines from an intersection of an area parting line and a border line of a character image, and extracting the feature quantity of the left and right irregular shapes of the character, based on the reference lines as a reference. CONSTITUTION:By scanning a character image by an outline tracking/area parting line determining program 4, an outline picture element of a character image is tracked counterclockwise or clockwise and outline tracking data is stored in a RAM 3. Subsequently, a horizontal projection of a direction code of the outline picture element is generated, and an upper and lower area parting line of the character image is determined. Next, by a reference line setting program 5 for detecting an intersection of an area parting line and an outline, the left and right reference lines of the character image is determined from the extracted intersection. Thereafter, by extracting a histogram of a direction code of the character image by the left and right reference lines, a difference of the left and right irregular shapes of the character can be discriminated easily. In such a way, for instance, D and O can be discriminated easily.
