제1도는 팩시밀리 시스템도, 제4도는 본 발명의 제어 흐름도, 제5도는 본 발명에 따른 연속성 고려 마스크도.1 is a facsimile system diagram, FIG. 4 is a control flowchart of the present invention, and FIG. 5 is a continuity consideration mask diagram according to the present invention.

Claims (1)

팩시밀리 시스템의 혼재 문서 식별방법에 있어서, 처리하고자 하는 원 문서의 조측 상단부터 우측 하단까지 순서대로 한 화소씩 스캐닝하여 현재의 화소에 대해 MxL(M 및 L은 자연수)의 국부적인 창을 씌우는 제1과정과, 상기 제1과정에서 창내의 화소들이 갖는 밝기 값들 중에서 최대값과 최소값을 구하는 제2과정과, 상기 제2과정으로 부터 구하여진 최소값이 미리 정의된 제1역치 Tmax보다 크면 현재의 화소가 배경 부분에 속한다고 식별하여 그 화소를 백으로 처리한후 상기 제1과정으로 리턴하는 제3과정과, 상기 제2과정으로 부터 구하여진 최대값이 미리 정의된 제2역치 Tmin보다 작으면 현재 화소가 문자 내부에 존재한다고 식별하여 그 화소를 혹으로 처리한후 상기 제1과정으로 리턴하는 제4과정과, 상기 제2과정으로 부터 구하여진 최대값과 최소값의 차가 미리 정의된 제3역치 P보다 크면 현재 화소가 문자 영역에 속한다고 식별하여 그 화소를 국부 적응 2치 분할법으로 처리한후 상기 제1과정으로 리턴하는 제5과정과, 상기 제3-5과정으로부터 각 조건을 만족하지 않았다면 현재 화소를 영상 영역으로 간주하고 다음 처리될 화소들을 위하여 거 화소의 연속성 상태 비트를 온으로 만든후, 모든 연속성 상태 비트가 온인가를 판단하는 제6과정과, 상기 제6과정으로 부터 모두 온이면 현재 화소가 실 영상 영역에 속한다고 판단하여 디더링 처리후 제1과정으로 리턴하는 제7과정과, 상기 제6과정으로 부터 모두 온이 아니면 현재의 화소를 미리 정의된 제4역치 T와 비교하여 2 분할법으로 처리하는 제8과정으로 이루어짐을 특징으로 하는 영상 및 문자 혼재 문서의 간이 식별방법.A method for identifying a mixed document of a facsimile system, comprising: scanning a pixel from a top side to a bottom right of an original document to be processed one by one in order to cover a current window with a local window of MxL (M and L are natural numbers) And a second step of obtaining a maximum value and a minimum value among brightness values of the pixels in the window in the first step; and a current pixel when the minimum value obtained from the second step is greater than a first predetermined threshold Tmax. A third process of identifying that it belongs to a background part and processing the pixel as a bag, and then returning to the first process, and if the maximum value obtained from the second process is less than a predefined second threshold value Tmin, the current pixel Process is to identify that is present inside a character, and processes the pixel into a hog, and then returns to the first process, and the maximum and minimum values obtained from the second process. If the difference is greater than a predefined third threshold value P, a fifth process for identifying that the current pixel belongs to the character area, processing the pixel by the local adaptive binary division method, and returning to the first process, and the third to fifth processes A sixth step of considering the current pixel as an image region if the condition is not satisfied from and turning on the continuity status bit of the giant pixel for the next pixel to be processed, and then determining whether all the continuity status bits are on; If it is all on from step 6, it is determined that the current pixel belongs to the real image area, and the seventh step of returning to the first step after the dithering process; And an eighth step of processing in a two-division method compared to the four threshold value T. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
