CHARACTER RECOGNITION DEVICE, METHOD THEREFOR AND COMPUTER READABLE RECORDING MEDIUM RECORDING THE METHOD AS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a character recognition device for finding a horizontally written character string included in vertically written character rows in character images and correctly recognizing characters. SOLUTION: A binary picture input part 101 inputs the document images of a recognition object as binary pictures and a character constituting element detection part 102 detects character constituting elements from the binary pictures. A character row extraction part 103 connects the character constituting elements and extracts a character row. A character row direction judgement part 104 judges the direction, an extraction part 105 extracts a character area from the character row and a character recognition part 107 collates it with a recognition dictionary 106 and recognizes the character. A horizontally written character string judgement part 108 judges the presence/absence of the possibility of the horizontally written character string based on the recognized character. At the time of judging that it is present, a horizontally written character string division recognition part 110 divides the character images in a horizontal direction and recognizes new character images by collating them with the recognition dictionary 106. A recognized result output part 111 selects the one of high similarities of recognized results.
