  • Images are an important element in patents and many experts use images to analyze a patent or to check differences between patents. However, there is little research on image analysis for patents partly because image processing is an advanced technology and typically patent images consist of visual parts as well as of text and numbers. This study suggests two methods for using image processing; the Scale Invariant Feature Transform(SIFT) algorithm and Optical Character Recognition(OCR). The first method which works with SIFT uses image feature points. Through feature matching, it can be applied to calculate the similarity between documents containing these images. And in the second method, OCR is used to extract text from the images. By using numbers which are extracted from an image, it is possible to extract the corresponding related text within the text passages. Subsequently, document similarity can be calculated based on the extracted text. Through comparing the suggested methods and an existing method based only on text for calculating the similarity, the feasibility is achieved. Additionally, the correlation between both the similarity measures is low which shows that they capture different aspects of the patent content.

  • Surrealism, appeared in the beginning of the 20th century and affected almost all art fields, is one of the most representative art trends. Surrealism, not restricted from any rules and traditions but tried to produce a new appreciations in the world of dream and unconsciousness, also has affected fashion. In this paper, I have tried to find out how the surrealism has been expressed in the modern fashion, especially in Thierry Mugller's design. Thierry Mugler is one of the most famous designers who have expressed surrealism in their fashion designs. I have classified his designs and researched them by the application into the human body and the nature, by the metaphor and transformation of things, and by the metamorphosis of location and an optical illusion. It was based on Depaysement which is one of the ways in surrealistic expressions. The result of the study is followings; First, surrealism made fashion design possible to creat unlimitedly and sublimated it anew modern beauty by attempting the varieties of the fashion, not restricted from any rules and traditions. Second, surrealism made the general public to complete anew recognition and valuation about fashion by expressing the external character and the internal meaning on the clothes. Third, surrealism made people to recognize, which clothes is not simply wearing thing but also one of the art expression forms.

  • In the EPC(Engineering Procurement and Construction) project of the plant, procurement engineering has a profound effect on the profitability of the project. It is important that the procurement specifications are well written to ensure that procurement engineering works properly. In the meantime, the procurement specifications have been created by the experience of the person in charge because there was no system for helping procurement engineering. To cope with this situation, we are developing a procurement engineering management support system (PeMSS). This paper describes how to implement a knowledge-based service in the procurement engineering management support system. First, we briefly introduce the PeMSS, the knowledge base application field, and how to apply it. The parts that requires knowledge-based service are parsing the requirements in the PDF (Portable Document Format) file and management of the document provided by the supplier of the equipment.

  • As the 4th Industrial Revolution emerged as a key to improving national competitiveness, OCR technology, one of the major technologies in the 4th industry is in the spotlight. Since characters in various images contain a lot of information, OCR technology for recognizing these characters has evolved into technology used in many industries. In this paper, trends in OCR technology were identified and predicted using thesis data published in 'RISS' and patent data by International patent classification (IPC) under the theme of Optical character recognition (OCR). For patent data 20,000 patents related to OCR technology from 2002 to 2020 were used as data, and 432 papers from 2012 to 2022 were used as data. Through time-series analysis, each patent data and thesis data were investigated since when OCR technology has developed, and various keyword analysis predicted which technology will be used in the future. Finally, the direction of future OCR technology development was presented through network association analysis with patent data and thesis data.

  • In this paper, we propose a real-time bus arrival notification system using deep learning to guarantee movement rights for the visually impaired. In modern society, by using location information of public transportation, users can quickly obtain information about public transportation and use public transportation easily. However, since the existing public transportation information system is a visual system, the visually impaired cannot use it. In Korea, various laws have been amended since the 'Act on the Promotion of Transportation for the Vulnerable' was enacted in June 2012 as the Act on the Movement Rights of the Blind, but the visually impaired are experiencing inconvenience in using public transportation. In particular, from the standpoint of the visually impaired, it is impossible to determine whether the bus is coming soon, is coming now, or has already arrived with the current system. In this paper, we use deep learning technology to learn bus numbers and identify upcoming bus numbers. Finally, we propose a method to notify the visually impaired by voice that the bus is coming by using TTS technology.

  • 블록체인은 다수의 노드 네트워크 내에서 거래내역을 분산 저장함으로써 투명성을 확보하는 기술이다. 최근에는 금전적 가치를 지닌 선하증권(Bill of Lading, B/L 서류)에 블록체인을 적용하여 무결성을 확보하고 거래 과정을 간소화 하기위한 연구가 진행되고 있다. 본 논문에서는 거래자 중심의 블록체인 기반의 선하증권 시스템을 제안한다. 수출자는 발행 받은 선하증권을 AI(Artificial intelligence)기반의 OCR(Optical character recognition)기능을 통해 블록체인에 등록하고, 각국 은행에서 열람하여 신용장거래를 진행한다. 수입자는 선하증권 정보를 담은 QR(Quick Response code)코드로 자기증명을 하여 물품을 인도 받게 된다. 이는 수출자 측에서는 선적서류를 우편으로 보낼 시간과 비용을 단축하고, 서류의 무결성을 입증할 수 있다는 점에서 큰 효과를 얻을 수 있다. 수입자 측에서는 서류가 등록됨과 동시에 확인할 수 있고, 해당 거래를 신뢰할 수 있다는 이점을 갖는다. 마지막으로 은행 측에서는 선적서류에 대해 보안성을 갖출 수 있고 검증이 더 신속하게 이루어질 수 있다.

  • 우리 사회에서 개인이 복용하고 있는 약물의 종류와 수가 점점 늘어나고 있다. 약물의 사용이 증가하면서 때로는 치명적일 수 있는 약물 오남용 또한 빈번히 발생하고 있으며 특히 노년층과 같이 약품을 정확하게 구별할 수 없는 사람들은 더욱더 그 위험에 노출되어있다. 본 논문에서는 사용자가 간단한 사진을 찍는 행위를 거치면 약물의 정보를 제공하고, 복용법을 알 수 있는 모바일 애플리케이션에 관하여 기술한다. 이를 구현하기 위하여 세밀한 시각적 분류 (Fine-Grained Visual Categorization, FGVC) 기법과 광학 문자 인식 (Optical Character Recognition, OCR) 기법을 결합한 인공지능 모델을 사용하였으며, React Native 를 사용하여 운영체제에 종속되지 않도록 애플리케이션을 제안한다. 이 애플리케이션은 노년층에 친화된 UI/UX 로 디자인되었으며, 약물의 정보 제공 이외에도 개인 약물 관리, 주변 약국 길 찾기 등의 편의 기능을 통해 노년층에 삶의 질 향상을 기대할 수 있을 것이다.

  • 커져만 가는 비건 시장에 비해서 비건 제품의 가격은 높고, 한정되어 있다. 성분표만을 보고 비건 여부를 파악하기에는 어렵고, 저시력자 및 시각장애인에게는 더욱 어려운 일이다. 치주 질환이나 당뇨를 포함한 크고 작은 다양한 질병으로 인해 육식 섭취 대신 불가피하게 채식을 실천해야 하는 경우 또는 가격 부담이 크고 찾기 어렵다. 그래서 비건 인증을 받은 제품 대신 일반 제품들 사이에서 비건에 적합한 제품을 찾는 데 도움이 되는 시스템을 개발하고자 한다. 본 논문에서는 저시력자 및 시각장애인을 위한 큰 글씨 화면, 음성 입출력 시스템 제공과 성분표 촬영을 통해 비건 적합 여부 및 알레르기 정보 제공, 사용자 특성 분석을 통한 UI 구성의 서비스를 제공한다. 성분표 촬영에 어려움을 겪는 저시력자 및 시각장애인에게 편리를 제공하기 위해 소프트웨어 뿐만 아니라 하드웨어를 구성한다.

  • With the advances of the big-data process technology, acquiring the real-time information from the massive image data taken by a mobile device inside a vehicle will be possible in the near future. Among the information that can be found around the vehicle, the route information is needed for safe driving. In this study, the automatic extraction of route information from the road sign imagery was dealt with. The scope of the route information in this study included the route number, route type, and their relationship with the driving direction. For the recognition of the route number, the modified Tesseract OCR (Optical Character Recognition) engine was used after extracting the rectangular-road-sign area with the Freeman chain code tracing algorithm. The route types (expressway, highway, rural highway, and municipal road) are recognized using the proposed algorithms, which are acquired from colour space analysis. Those road signs provide information about the route number as well as the roads that may be encountered along the way. In this study, such information was called “OTW (on the way)” or “TTW (to the way)” which between the two should be indicated is determined using direction information. Finally, the route number is matched with the direction information. Experiments are carried out with the road sign imagery taken inside a car. As a result, route numbers, route number type, OTW or TTW are successfully recognized, however some errors occurred in the process of matching TTW number with the direction.
