The epigraphy is a text or a picture engraved on metal or stone. One of advantages of rubbing of ancient inscription has been used in epigraphic field is simple. But the rubbing is not an optimal method in viewpoints of resolution and noise to decode the inscribed characters. In this study, we proposed a new research method that increases the possibility of a reading by reflecting the 3D characteristics of the engraved letters. The proposed techniques apply 3D scanning technology to obtain three-dimensional and high quality data of each of the letters in the epigraphy and use Ambient Occlusion visualization techniques to express the shade according to the 3D form of the letters. Research result enhances the readability of the letters that removed the damaged and worn information from the letters information of surface. This research contributes to narrow the scope of a particular letter and read to the controversial letters on the Pohang Jungsoengri Silla Stone Monument(Korea's national treasure number 318).

This paper aims to introduce Park Seon-su's ShuowenJiezi YIzheng from the perspective of Epigraphy, and incorporate it into the fields of Korean Epigraphy. Korean Epigraphy, which now categorized as a study since Kim Jeong-hee's powerful work in 19th century, can be listed either by studies published before and after Kim Jeong-hee's and by name of influential writers who have successfully presented each study and strive for the development of Korean Epigraphy. Earlier studies show that Korean Epigraphy has more books of data collection rather than the books of research on the epigraph. Regardless of the nationality of the author, all books containing Korean epigraph were counted as Korean Epigraphy, and those books made for religious reasons were not excluded from Korean Epigraphy as well. This indicates how wide the scope of Korean Epigraphy is. In this The reason Park Seon-su's research is ignored at present time, which was assessed as excellent in the late Chosun Dynasty, may come from lack of understanding on the ShuowenJiezi YIzheng. His book, ShuowenJiezi YIzheng, focuses on graphology but more broadly it includes translation of Epigraph and Epigraphy which leads to interpretation of scriptures. Such Park- Seonsu's great work must be presented in Korean Epigraphy studies to broaden its scope, also it is important to look for yet unfound pieces on the fields of Epigraphy.

This study proposes a new scientific measurement method for damaged epigraph. In this new method, the Chinese characters are converted and coordinates are created for this measurement. This method is then used to decipher partially damaged characters from the parts of the coordinated characters that are damaged and intact. The Chinese characters are divided into 9 square parts by the position of their Chinese Radicals. The unknown characters are then compared and deciphered dependent upon the character shape in 9 square parts that have been created. This method is more scientific, accurate, and makes it easier to find related characters than deciphering through contexts, which is current method. When creating a new software based on this algorithm, it will be especially useful in deciphering an old manuscript or a epigraph that made ancient Chinese characters which are not currently in use. This study will also be helpful in deciphering semi-cursive styled or cursive styled epigraph, as well as semi-cursive styled or cursive styled damaged characters during follow-up research.

선사 이래 인류의 대표적 고대 문화유산의 하나가 금석문이다. 이런 금석문들은 다양한 과학적 기법들로 그 원 형태를 인식하고자 하는 노력을 하고 있다. 그러나 가장 오래되고 유용한 보존과 인식 방법은 탁본에 의한 것이다. 그러나 원 자료의 심각한 훼손으로 탁본자료의 형상 인식이나 문자 인식은 일반적인 이미지 복원 방법과는 다양한 면에서 차이를 보이고 있어 이의 노이즈를 제거하고 원이미지를 복원하여 형상을 인식하는 것이 중요하다. 이러한 탁본의 판독에는 다양한 잡음들이 있어 이를 전문적인 판독가 들도 이설을 제기하는 경우들이 있다. 다양하고 심각한 훼손 상태에 있는 탁본의 이미지들은 다양한 형태의 심각한 노이즈를 가지고 있어 전통적이고 일반적인 이미지 향상이나복원 기법들을 적용하기에 적절하지가 않다. 본 연구에서는 구름이나 야간 상황 등 다양한 노이즈를 가진 SAR 이미지처리 기법과 다양한 환자들의 다양한 병적 상태의 이미지들에 효과적으로 적용되는 방법들을 살펴 탁본 문자인식에 적용하고 그 효과를 히스토그램과 이미지 엔트로피를 이용하여 측정하고자 하였다.

An epigraph is an inscription mainly on a metal or stone monument, but some cases on bones or tortoise carapaces, ceramics, and coins. The '茶' inscriptions in 251 epigraphs in Korea are on 16 monuments, one tile, and one ceramic. By kingdom 5 belongs to shilla and 13 to Korea. The first '茶' inscription in on the Changsung-Tap of Borimsa Temple in Changhung-Kun, Chullanam-Do, which was established in 884 A.D. Religiously most of them are related to Buddism. Tea was most valued among valuables like gold, perlume, beads, etc. and so bestowed by kings. The study of epigraphs shows that our tea culture had most prospered diring the Kingdoms of Shilla and Korea.

금석문의 영상데이터를 디지털 형태로 검출하고, 영상신호처리 알고리즘을 사용하여 신호의 특성을 분석하고 그 결과를 제시하였다. 대상체는 비석에 음각된 문자로 하였다. 대전 주변의 백제권에서 몇몇 유형의 음각 문자를 형태별로 분류하여 디지털 이미지화한 다음, 문자가 각인된 정보영역과 바탕영역의 신호패턴을 추출하였다. 먼저 칼라 이미지를 grey tone으로 변환한 후, 전처리 과정을 거쳐 이미지의 노이즈나 불명확성을 제거하고 히스토그램 전 영역에 걸쳐 스케일 확장시켰다. 문자가 각인된 정보영역과 바탕영역을 구분하여 무작위로 소이미지 샘플을 취득하고 각 소이미지의 신호패턴을 분석하였다. 그 결과를 중첩의 원리를 이용하여 합성한 후 영역별 신호분석 패턴을 정형화하였다. 유형별로 다소 차이를 보이나 두 영역의 이미지 분석 결과는 차별성을 보였다. 문자 영역은 grey level 범위가 좁고 한정되며 일관성을 보이는데 비해, 바탕영역은 범위가 넓고 광범위하였다. 두 영역의 교차 레벨 범위는 극히 제한적이었으며 패턴 분리에 큰 영향을 끼치지 못하였음이 밝혀졌다. 이 일련의 과정은 알고리즘화되어, 1-2분 정도의 사전 작업만 하면 프로그램에 의해 문자를 추출할 수 있다. 이러한 사실들은 종래 무리한 탁본 작업에만 전적으로 의존하던 금석학 분야의 디지털화를 가능케 할 수 있다.

In this paper, we investigate an enhancement method for Western epigraphic images, which is based on local statistics. Image data is partitioned into two regions, background and information. Statistical and functional analyses are proceeded for image modeling. The Western epigraphic images, for the most part, have shown the Gaussian distribution. It is clarified that each region can be differentiated statistically. The local normalization process algorithm is designed on this model. The parameter is extracted and it‘s properties are verified with the size of moving window. The spatial gray-level distribution is modified and regions are differentiated by adjusting parameter and the size of moving window. Local statistics are utilized for realization of the enhancement, so that difference between regions can be enhanced and noise or speckles of region can be smoothed. Experimental results are presented to show the superiority of the proposed algorithm over the conventional methods.

This study aimed to demonstrate that photographic reading can be used to decipher epigraphs more effectively and accurately than conventional rubbing of epigraphy. When using the rubbing technique, the reading rate varies for the each epigraph depending on the time, person, and rubbing method. Thus, we compared the results of conventional rubbing to photographic reading focusing on unread and misread letters. According to the results, some letters were different from those in the reference books, and some letters that could have been readable via photographic reading were misread or read as different letters. In its undamaged state, the Pyeongwangtapbi Monument of Seonggak Daesa is supposed to contain a total of 2,049 letters, and 1,763 of them have been deciphered. This study corrected a total of 308 letters that had not been deciphered or deciphered inconsistently in existing literatures. However, it should be noted that the epigraphs of the Pyeongwangtapbi Monument of Seonggak Daesa read using the rubbing technique were made at least 30-100 years ago, and the photographic reading was performed in 2010. Thus, the overall condition is not perfectly identical. If we read and compare in the same condition, we may obtain even more reliable results. Therefore, based on this study of photographic reading, further studies regarding the correction of the contents of epigraphy should be performed.
