Description

문자 인식의 패턴 매칭 장치 및 그 방법Pattern matching device for character recognition and method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명 장치의 회로도,1 is a circuit diagram of an apparatus of the present invention,

제2도는 본 발명 방법의 플로우챠트,2 is a flowchart of the method of the present invention,

제3도의 (가)-(마)는 본 발명 방법에 의한 거리 계산 과장도.(A)-(e) of FIG. 3 is an exaggeration diagram of distance calculation by the method of the present invention.

Claims (2)

CPU(1)에 의해 제어되어 표준데이타의 미소 메쉬데이타를 출력시키는 제1RAM(2)과; 상기 CPU(1)에 의해 제어되어 현재 문자영상의 미소 메쉬데이타를 출력시는 제2RAM(3)과; 상기 제1및 제2RAM(2,3)에서 출력되는 표준 및 현재 미소메쉬데이타를 각각 배타 논리합하는 다수개의 익스클루시브 오어게이트(4-7)와; 상기 익스클루시브 오어게이트(4-7)의 출력을 계수하는 계수기(8)와; 프로그램 내장용 ROM(9)의 구비되어 상기 계수기(8)의 출력값에 따라 제1및 제2RAM(2,3)에 소정의 인에이블 신호를 제공하는 CPU(1)와를 구비하여서 됨을 특징으로 하는 문자인식의 패턴 매칭 장치.A first RAM 2 controlled by the CPU 1 for outputting micro mesh data of standard data; A second RAM (3) controlled by the CPU (1) for outputting micro mesh data of the current character image; A plurality of exclusive or gates 4-7 exclusively ORing the standard and current micromesh data output from the first and second RAMs 2 and 3, respectively; A counter 8 for counting the output of the exclusive or gate 4-7; And a CPU 1 having a program-integrated ROM 9 for providing predetermined enable signals to the first and second RAMs 2, 3 according to the output value of the counter 8; Pattern matching device of recognition. 문자형상이 입력되면 이를 NxN으로 메쉬한 다음, 각각의 메쉬를 다시 미소하게 2×2로 메쉬시켜 각 메쉬의 형태를 결정한 후 제1RAM(2)에 기억된 표준데이타의 미소 메쉬데이타와 상호 비교하여 거리를 계산한 다음 거리의 합이 최소가 되는 글자를 인식하는 과정으로 이루어 짐을 특징으로 하는 문자 인식의 패턴 매칭 방법.When the character shape is input, mesh it with NxN, and then mesh each mesh to 2 × 2 finely to determine the shape of each mesh, and then compare with the micro mesh data of the standard data stored in the first RAM (2). A method of pattern matching in character recognition, comprising calculating a distance and then recognizing a character whose sum is the minimum. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
