본 논문에서는 영상 인식을 위해 그레이 레벨로 획득된 영상을 이진화할 때 발생되어 패턴의 윤곽선을 울퉁불퉁하게 만드는 랜덤 노이즈를 제거하기 위한 방법으로 체인 코드 트리밍(chain code trimming) 을 제안한다. 제안된 방법은 패턴의 외부 윤곽선과 내부 윤곽선의 체인 코드 분석을 통해 랜텀 노이즈의 체인 코드를 제거, 교정함으로서 이루어진다. 실험에서는 트리밍을 사용하기전과, 단순 트리밍을 한 경우, 체인 코드 트리밍을 한 경우를 서로 바로, 분석한다. 실험 결과는 패턴에 첨부되었던 랜덤 노이즈가 모두 성공리에 제거된 것을 보인다.

This paper proposes a new method of weighted template matching for machine-printed numeral recognition. The proposed weighted template matching, which emphasizes the feature of a pattern using adaptive Hamming distance on local feature areas, improves the recognition rate while template matching processes an input image as one global feature. Template matching is vulnerable to random noises that generate ragged outlines of a pattern when it is binarized. This paper offers a method of chain code trimming in order to remove ragged outlines. The method corrects specific chain codes within the chain codes of the inner and the outer contour of a pattern. The experiment compares confusion matrices of both the template matching and the proposed weighted template matching with chain code trimming. The result shows that the proposed method improves fairly the recognition rate of the machine-printed numerals.

Purpose of this study is to develop fashion design with greater added value and to seek the expandability of its expression domain by applying special computer code and tape embroidery machine capable of creating more special and fancier fashion to the development of fashion design by focusing on the fashion decorations that are becoming increasingly more computer systematized. For this purpose, expression techniques and effects of computer embroidery machine code and tape trimming decoration techniques, and cases of modern fashion design are examined. Major images are then deduced to designing and production of actual 6 creative pieces equipped with creativity and commercial value by applying such images deduced. As the results, it is not only possible to develop highly value added fashion design by utilizing mixed computer embroidery machine code and tape trimming decoration technique but also to produce countlessly new and unique surfaces by inducing changes in diversified pattern expressions, thickness of cord thread, and width, color and texture of material, etc. of the tape. This can maximize the expression domain of design, and fulfill the fashion desires of consumers wanting modern enhancement of quality and individualization. If multilateral attempts and studies for the aforementioned purposes can be expanded continuously, it is deemed possible to broaden the range of expression techniques in fashion design and, moreover, to make contribution towards enhancement of competitiveness of fashion industry.
