Information retrieval is one of the most challenging areas in which the ontology technology is effectively used. Among them image retrieval using the image meta data and ontology is the one that can substitute the keyword-based image retrieval. In the paper, the retrieval of visual media such as the art image and photo picture is handled. It is assumed that there are more than one service providers of the visual media and also there is one central service broker that mediates the user's query. Given the user's query the first step that must be done in the service broker is to get the list of candidate service providers that fit the query. This is done by defining various ontologies such as the service ontology and matching the query against the ontology and providers. A novel matching method based on the ASN.1. The experiment shows that the method is more effective than existing tree-based and interval-based methods. Ontology merging issue is also handled that can happen when the service providers register their service into the service broker. An effective method is also proposed.

In this paper, it suggested Android smart phone application for users who want to find valley at summer. To provide correct information, we used Korea Tourism Organization's tourism information database and to provide tourism information and map service at once we linked Naver map. Search valley application can search valley by using country's region name and keyword by using map and GPS. we can find restaurants accomodations around your location. we can get restaurants and accommodations by control distance so we can get phone number, pictures and detail information about searched data. Also, you can bookmark valley where you want to go and you can search of delete bookmarked valley whenever you want. you can share opinion by writing postscribe about the valley where application user went. for developer and users amicable communication we made Q&A board.

This thesis implements retrieving systems with easy to retrieve photos which end-user want to find based m end-user computing(EUC)'s a theoretical study on factors in exert a effect on the computing systems. And also this systems allow a photographer to store his works in the database of this systems by himself on internet environment. This sock photo systems is developed with object oriented design methodology so it is easy to modify and to reuse software. And this systems can use for electronic commerce by adding the electronic payment systems.

소셜 미디어(Social Media)란 사람들이 의견, 생각, 경험, 관점 등을 서로 공유하기 위해 사용하는 온라인 툴과 플랫폼을 뜻한다. 여행에서 가장 중요한 정보는 위치와 경로 정보이다. 하지만 우리가 다른 사람들의 여행정보를 검색하여 보면 위치와 경로 정보를 보여주는 방법으로는 지도를 캡처하여 그 위에 직접 경로를 그린 뒤 그림파일로 저장하여 올려서 사진처럼 보여주는 경우가 대부분이며 지도를 제공하는 여행 블로그 사이트에서는 출발 정보와 목적지 정보를 입력하면 지도 위에 목적지와 그 사이를 선으로 연결하여 같이 보여주는 정도의 서비스를 제공한다. 또한 지도 위의 정보와 실질적인 여행 정보, 즉 사진이나 여행자의 메모나 생각 같은 글이 연결되어 보여주지 못한다. 이에 본 연구에서는 사용자가 자신의 여행기를 정리하고 표현하는데 있어서 지도 위에서 자유롭게 사용자의 의도대로 표현할 수 있는 인터페이스를 생성하는 것을 목표로 한다.

This paper proposes a system to analyze and summarize the video shots of baseball game TV program into fifteen categories. Our System consists of three modules: feature extraction, Hidden Markov Model (HMM) training, and video shot categorization. Video Shots belongs to the same class are not necessarily similar, so we require that the training set is large enough to include video shot with all possible variations to create a robust Hidden Markov Model. In the experiments, we have illustrated that our system can recognize the 15 different shot classes with a success ratio of 84.72%.

캐리커처 생성 시스템은 입력된 인물 사진을 세그먼테이션을 통하여 특징(이목구비)을 추출하고, 추출된 특징정보를 이용하여 그와 유사한 특징정보를 가지는 캐리커처 이미지를 검색하여 매핑시키는 시스템이다. 캐리커처 생성 시스템에서는 얼굴의 대칭 구조를 이용하고 색상과 모양에 대한 정보를 이용하여 얼굴 각각의 특징(이목구비)을 캐리커처의 특징을 구분하는 특징정보로써 활용한다. 본 논문은 인물 사진을 세그멘테이션 처리하여 얻은 부분 영역 특징정보를 이용하여 그와 유사한 캐리커처를 자동으로 생성하는데 목적이 있다. 이 때 사용하는 대칭 구조는 씨앗 픽셀(seed pixel)을 추출한다. 특징정보는 색상의 경우 지역적인 색상정보는 이목구비를 더 뚜렷이 해주고, 전체적인 색상정보는 그 이미지의 피부색의 정보를 나타낸다. 모양의 경우 이목구비의 특징정보를 위해 불변모멘트가 주요하게 사용된다. 또한 데이터베이스는 얼굴의 세부사항(이목구비)에 대한 각각의 캐리커처로 구축되어 있고, 각 세부사항은 특징별 분류되어 있어야 한다. 이런 데이터베이스의 캐리커처와 추출된 얼굴 영상에서의 세부사항을 비교하여 유사도를 계산하고 이를 매핑하므로 개인의 특징을 가진 캐리커처를 자동으로 생성한다.

This study starts from the hypothesis that the information society has affected the layman's interpretation and production of content. Specifically, the manner and contents of communication concerning the landscape of Soonyoo-do Park in blogs are surveyed and the possibilities and limitations of this phenomenon are discussed. The following topics are dealt with. Firstly, what is the landscape of Seonyoodo Park as captured by bloggers? What type of landscape do bloggers respond to? Secondly, what is the unique way that bloggers capture and interpret the landscape? Thirdly, What are the possibilities and limitations discovered from the landscape as captured and interpreted by bloggers? Thus, 1,000 blog posts concerning Soonyoo-do Park, as culled from the Internet, were categorized into three areas, First are blog posts browsed by keywords such as 'photo', 'a photographer's visit', 'a good p1ace for taking photos', and 'landscape'. These are focused on the visual aspects of the landscape. The second category is posts under the keywords 'domestic travel', 'Seoul travel', 'travel', and 'recommendation'. They contain introductory information on Seonyoodo Park; that is, they focus cm the more utilitarian functions of Seonyoodo Park as a place. The third one is posts that record personal experiences. The subjects for photography are the bloggers themselves and their companions. As a result of studying the way bloggers deal with landscape, it was found that first, people have developed the ability to capture the landscape and interpret the landscape actively and independently. This process can be regarded as the reproduction of landscape and place. In addition, the recording of their appreciation and feeling overlaps with evaluation and assumption. One negative aspect, however, is that many bloggers dramatize and repeat similar scenes. This can be seen as a make-up of image. The limitations of this study include difficulty in interpretation because blogs, which are the objects of this study, are very subjective and personal. In addition, it was not easy to categorize posts because there were diverse images and a broad range of writing. Nevertheless, practitioners of landscape architecture should continue to monitor and use one-person media like blogs, because the relationship between modern man and the landscape can be better understood through them.

Recently in order to more effectively and scientifically process forest official tasks, which have been focused on documents and inventories, they should be applied with the up-to-date spatial information technologies. Especially, the forest resource information management based on GIS(geographic information system) and aerial orthophoto is expected not only to play an important role as DSS(decision support system) for domestic forest conservation policy and forestry development industry but also to service forest resource information toward people such as the owners of a mountain rapidly. In this study, the important forest information such as digital topography map, digital forest type map, digital forest cadastral map, digital aerial photographs and attribute data were first reprocessed and constructed in DBMS(data base management system). In addition, forest officials could analyze and retrieve forest information by using detail sub-application systems such as forest cadastral retrieval, forest land development information management, reserved forest information management and forest resource information retrieval. For this, the user interface is developed by using Visual Basic 6.0 and MapObjects 2.1 of ESRI based on CBD(component based development) technology. The result of developing this system will not only perform constructing economical forest and better environment but also be the foundation of domestic spatial technology for forest resource management.

Five land use change detection methods were applied to 1994 and 1997 Landsat Thematic Mapper (TM) images of Pook-Gu, Taegu city to determine the land-cover changes between the two dates. The two images were coregistred to UTM coordinates. A post-classification comparison method was the most commonly used quantitative method of change detection. A pre-classification comparison method was more effective method to change detection of land cover than a post-classification comparison method. Two indices were used to assess the accuracies of the studied methods. A image differencing method was found to be most accurate for detecting change verse no change among five land use change detection methods. The difference image of band 2 was found to be most accurate. The overall accuracy and Kappa index agreement of the difference image of band 2 were 0.810 and 0.447.
