      • 주석 및 특징을 이용한 의미기반 비디오 검색 시스템

        이종희 대한전자공학회 2004 電子工學會論文誌-CI (Computer and Information) Vol.40 No.12

        비디오 데이터를 효율적으로 처리하기 위해서는 비디오 데이터가 가지고 있는 내용에 대한 정보를 데이터베이스에 저장하고 사용자들의 다양한 질의를 처리할 수 있는 의미기반 검색 기법이 요구된다. 기존의 내용기반 비디오 검색 시스템들은 주석기반 검색 또는 특징기반 검색과 같은 단일 방식으로만 검색을 하므로 검색 효율이 낮을 뿐 아니라 완전한 자동 처리가 되지 않아 시스템 관리자나 주석자의 많은 노력을 요구한다. 본 논문에서는 주석기반 검색과 특징기반 검색을 이용하여 대용량의 비디오 데이터에 대한 사용자의 다양한 의미검색을 지원하는 에이전트 기반에서의 자동화되고 통합된 비디오 의미기반 검색시스템을 제안한다. 사용자의 기본적인 질의와 질의에 의해 추출된 키 프레임의 이미지를 선택함으로써 에이전트는 추출된 키 프레임의 주석에 대한 의미를 더욱 구체화시킨다. 또한, 사용자에 의해 선택된 키 프레임은 질의 이미지가 되어 제안하는 특징기반 검색 기법과 최적 비교 영역 추출을 통해 가장 유사한 키 프레임을 검색한다. 따라서 의미기반 검색을 통해 비디오 데이터의 검색의 효율을 높일 수 있도록 시스템을 제안한다. In order to process video data effectively, it is required that the content information of video data is loaded in database and semantic-based retrieval method can be available for various query of users. Currently existent contents-based video retrieval systems search by single method such as annotation-based or feature-based retrieval, and show low search efficiency md requires many efforts of system administrator or annotator because of imperfect automatic processing. In this paper, we propose semantics-based video retrieval system which support semantic retrieval of various users by feature-based retrieval and annotation-based retrieval of massive video data. By user's fundamental query and selection of image for key frame that extracted from query, the agent gives the detail shape for annotation of extracted key frame. Also, key frame selected by user become query image and searches the most similar key frame through feature based retrieval method and optimized comparison area extracting that propose. Therefore, we propose the system that can heighten retrieval efficiency of video data through semantics-based retrieval.

      • 서로 다른 디스크 運營體制間의 相互 File 變換器 開發에 關한 硏究

        李鍾姬,趙錫煥 영남이공대학 1985 論文集 Vol.14 No.-

        In this paper, the algorithm for converting from Pascal text files to DOS 3.3 text files by analyzing file formats. In order to get the Pascal files, one has to access the diskette on a direct track/sector basis because of the difference between Apple DOS 3.3 system and Pascal system file formats. This method may be applied to other operating systems. The conversions between all systems, whose directories and sector organizations are known, are possible.

        중학생의 공간 시각화 능력에 대한 연구 : 3차원 회전 능력을 중심으로

        이종희,전선경 이화여자대학교 교과교육연구소 1998 교과교육학연구 Vol.2 No.2

        기하는 수학의 중요한 분야이며, 수학 교육의 목표 중 기하 교육을 통한 목표의 하나로 최근에는 공간 능력이 강조되고 있다. 본 논문은 공간 능력 중 공간 시각화 능력에 대해 수학 성취도와의 상관 관계를 조사하며, 학년이 올라감에 따라 공간 시각화 능력이 신장되는지를 조사함으로써, 현행 수학 교과서의 기하 영역이 제대로 구성되어 있는지를 분석한 보고서이다. Geometry is an important part of mathematics, and recently spatial ability is emphasized as one of many objects through geometry instruction in the objects of mathematics education. A lot of studies showing the relationship between spatial ability and mathematics achievement, and studies related to gender differences in spatial ability are being continued. Many educators of mathematics assert the extension of student's spatial ability through geometry instruction. But, there are few studies on the construction of geometry section in mathematics textbook with respect to extension of spatial ability. This study investigated the relationship between spatial visualization ability-a particular subset of spatial ability-and mathematics achievement. It investigated also the existence of extension of spatial visualization ability as ascending grades, so this study presents whether the geometry section in mathematics textbook is constructed adequately to that object. Two opposite type middle schools were sampled in this study: all-boys school, and all-girls school. This research got a Purdue Spatial Visualization-Rotations Test to all grades of the sample middle schools, and gathered mathematics scores of National Achievement Assessment tested last year for second and third grades (middle school) students. The results of this research as follows: First, there exist a positive relationship between spatial visualization ability and mathematics achievement in the middle school students. Second, there does not exist grades differences in spatial visualization ability of middle school students except for the difference between first - second grades of boy students, i. e., their spatial visualization ability does not be extended as ascending grades. Thus, the hypothesis was taken that the geometry section in mathematics textbook was one of the cause of no extension of spatial visualization ability And for the geometry section in first and second middle school mathematics textbook, the content construction was analyzed. As a result, the part related to spatial visualization ability in the geometry section is about 30.3% in first grade, and about 11.8% in second grade. This can be related the relative difference between the difference of average of 1-2grades(increasing 1.09) and the difference of average of 2-3grades(decreasing 0.02), in comparison with the grades difference of spatial visualization ability.

      • 이질성 구조를 갖는 신경회로망에 관한 연구

        李鍾熹 新羅大學校 1995 論文集 Vol.40 No.1

        There are two methods to imitate a human's brain. One is a symbolic processing artifical intelligence which programs knowledges in brains according to functions. The other is the artificial intelligence intending to implement the intelligence by using the brain's organization achieved from brain analysis. Between these, a symbolic processing artificial intelligence is the approach of level of functions-called Fuzzy Logic in other word. And we say it Neural Network the approach of the level of physiology. In this paper, a new fuzzy learning method of improved learing speed and convergence rate is proposed to exploit the advantages of artificial neural networks and fuzzy logic to neuron structure. This method is applied to the exclusive OR problem, Parity problem which is used as the benchmark in neurla network. As a result of the experiment, it does ot always guarantee the convergence. However, the proposed network shows an improved learning time and a high convergence rate. The proposed network is albe to extend the arbitrary layer. When we consider only a network of the single layer, the network has the capability of high speed during learning process and rapid processin on huge patterns.

      • 體操選手들의 競爭不安이 競技力에 미치는 影響에 關한 硏究 : 中, 高 學生을 中心으로

        이종희,김정주,김민철 경희대학교 체육과학연구소 1991 體育學論文集 Vol.19 No.-

        This research shows that Gymnastic players have a insecurity and how it effects on their records. The female or male 135 players (from 15 to 18 years old) because the subject of this written inquire. Trait anxiety was mearsured by Form X-2 of STAI(State-Trait anxiety) while State anxiety was measured by Form X-1. We compared the records in practicing. We trid to clarify the relationship between the ability in games and the anxiety. 1.Trait anxiety, State anxiety, Cometitive anxiety's got a correl ration each other. We compared with Trait, State anxiety with woman's players and we're got 0.95. We compared with Trait, Cometitive anxiety and we have 0.87. We compared with Trait, State anxiety with men's players and we're got 0.88. We compared with Trait, Cometitive anxiety and we have 0.89. We compared with State, Cometitive anxiety and we have 0.82. 2.The differrence between Men and Woman's anxiety has significance, It shows that Cometitive anxiety score's average-man's players has 36.89. Woman's players has 29.56. In general, the woman's players level of anxierty has a lower level than men's level but player's level of anxiety has getting increased. 3.The expect players have how level of anxierty than unexpect player's. In there are 4 years expect players and 8 years expect players,4 years expect players the level of anxiety is 38.32, 8 years expect players the level of anxiety is 28.74. 4.The differrence between educated and uneducated player has competition. Generally, the middle school student's level of anxiety has a higher than high school students.
