Artifact pattern representation of a method using the digital technology is largely are two digital rubbing technique and digital contrast technique. Digital rubbing technique is clearly with the naked eye to see the original prestigious and difficult to build a digital rubbing data patterns by scanning a prestigious and patterns carved into the artifacts in three dimensions without compromising the circle to represent the three-dimensional effect by contrast it to the objective value refers to a technique that can be represented in digital. Digital contrast technique can not be calculated if the depth information of the object due to the glassy film of artefacts in a three-dimensional surface scanning and the application of this technique refers to a realistic image mapped digital technique for generating digital image contrast. Digital rubbing technique is mainly useful to express the most prestigious and patterns expressed in pottery or tile and stone monument, etc. engraved or embossed, digital contrast techniques can be used effectively to artifacts such as magnetic or glass can not be applied to the digital rubbing technique.

최근 컴퓨터의 급속한 보급과 영상처리기술의 발달로 금석학 분야는 인문학의 범주를 뛰어넘어 문화 정보 공유의 중요한 위치로 자리매김하게 되었다. 본 연구는 국내에서 처음 시도 되는 것으로, 수천년 정신문화 산물의 정보자료인 탁본을 영상으로 입력하여 디지털 데이터로 전환하고, 이를 공간 영역에서 종합 분석함으로 탁본영상 고유의 특성을 파악하고자 하였다. 탁본 원영상은 흑백의 두 영역으로 분할되는 완벽한 이진영상이나, 탁본뜨기 수작업과정을 거치면서 관측영상에는 영역간 색도의 혼재가 발생하고 얼룩무늬와 문양이 전체 영상에 분포한다. 이와같은 영상으로부터 필요한 문자나 문양의 정보를 추출하기 위한 전단계로 영상에 관한 종합적인 분석 작업을 하였다. 분석 기법으로는 공간분석법을 사용하였다. 역사적으로 유명한 대표적인 탁본을 위시하여 40여개의 탁본영상 샘플을 무작위로 선택하였고, 공간분석을 통해 색도분포특성과 영역간 색도 중복 및 영역형성 양상과 특성을 찾아내었다.

Various decipherment technologies, including manual rubbing, have been continuously applied to the Goguryeo Stele in Chungju. However, an official document for advanced decipherment is required as there remain characters to be deciphered. This study focuses on interdisciplinary digital decipherment using digital visualization results based on reflectance transformation imaging and three-dimensional scanning. On that basis, the joint decipherment document in 2019 is classified into eight types according to character changes from 1979 to 2000, and decipherment achievements are discussed. Important outcomes of the joint decipherment document include a new interpretation of four existing characters and the identification of 28 new characters. Additionally, 68 characters on the front face and 20 on the left face, which are listed differently in previous decipherment documents, are determined to be a single character through a consensus process. Compared to the previous decipherment document, the "decision" character is increased by a total of 89 characters (22.6%), and the "different opinion" character is decreased by 126 characters (32.0%). Thus, this digital decipherment greatly contributes to the reexamination of the Goguryeo Stele in Chungju and complements the previous decipherment document through reflectance transformation imaging and three-dimensional scanning. However, continuous research is necessary to enhance decipherment rates, since 123 characters (31.3%) are yet to receive decipherment. In the future, decipherment advancement regarding the Goguryeo Stele in Chungju should be based on convergence research between the humanities and science. Furthermore, it seems that researchers must make constant efforts to apply new imaging analysis technology and to develop customized technology for decipherment.
