Abstract

There have been reports that the "jeongcho (定礎)" letters of the foundation stone at the historical site No. 280 of the "Main Building of the Bank of Korea in Seoul" were written by Prince Ito Hirobumi (伊藤博文), the first Resident-General of Japan in Korea. An on-site investigation by an advisory group consisting of three experts in calligraphy; revealed that the two characters of '定礎' inscribed on the foundation stone are the characteristics of Ito Hirobumi's handwriting, judging from the writing style and habits observed in the collections of the Central Library of Hamamatsu City, Japan. It was reported that his writing was confirmed by the experts, but no basis was provided. To provide more objective and quantitative supporting data, rather than qualitative judgment based on feeling, it is necessary to present the basis for judgment through quantitative image comparison results through image analysis. In this paper, using image analysis software, Ito Hirobumi's calligraphy writing and the inscribed characters of the foundation stone were compared and analyzed to confirm the contents of the press release. The character comparison process and character area measurement results are a good example showing that if objective judgment basis data are needed in a similar situation, an objective judgment basis can be prepared through quantification using image analysis.

사적 제280호 「서울 한국은행 본관」 정초석의 '정초(定礎)'글자가 조선통감부 초대통감이었던 이토 히로부미(伊藤博文)가 쓴 글씨라는 보도가 있었다. 서체 관련 전문가 3인으로 자문단을 구성하여 현지조사를 진행한 결과, 정초석에 새겨진 '정초(定礎)' 두 글자는 일본 하마마츠시(浜松市) 시립중앙도서관 소장자료상의 이토 히로부미의 필적과 운필법 등의 특징으로 그의 글씨임을 확인하였다고 보도되었다. 느낌에 의한 정성적인 판단 보다 객관적인 판단자료를 제공하려면 이미지분석을 통한 글자의 정량적인 비교를 통한 판단의 근거자료의 제시가 필요하다. 본고에서는 이미지분석 소프트웨어를 활용하여 이토 히로부미의 붓글씨와 정초석의 글자를 겹쳐 육안에 의한 비교와 글자의 면적을 측정하여 비교하였다. 이미지분석 소프트웨어를 활용한 글자 이미지의 비교분석과 소장자가 기술한 소장경위의 조사를 바탕으로 정초석의 글자가 보도자료의 내용대로 그의 글씨임을 확인하였다. 글자간의 유사성의 비교에 있어서 이미지분석법을 활용한 정량화를 통하여 객관적인 판단근거를 마련할 수 있음을 예시하였다.
