  • 모바일 비주얼 검색(MVS: Mobile Visual Search) 기술은 스마트폰 환경에서 질의 영상의 특징을 검출하고 그 주변 영역의 정보를 이용하여 추출한 서술자를 미리 구축된 영상정보 DB와 비교하여 검색하는 기술로 스마트폰의 보급과 네트워크 환경발달에 따라 응용서비스의 범위와 가능성이 확대되고 있다. 본 동향에서는 기존의 텍스트, 음성, QR코드 등의 검색을 넘어 인간이 보는 그대로를 검색하고자 하는 모바일 비주얼 검색의 기술 및 표준화 동향을 분석하고 향후 전망에 대해서 살펴보고자 한다.

  • A few bioinformatics tools have been used to find out conserved regions as probes. We have developed a system based on a heuristic method with web interfaces to find out conserved regions against microbial genomes. The system runs in real time by using relative entropy in limited narrow regions and detecting similar regions between pair regions with local alignment. The system could be useful to find out conserved regions as genome-wide scale.

  • This study identified convergent validity and discriminant validity of measurement variables by factor analysis using Spss program and tested covariance measurement model including latent variables such as the website attributes (interactivity, search and visual information of website), shopping values(utilitarian and hedonic value) and attitude toward website by AMOS program. The data were collected from a sample of 271 internet shopper of university students(male: 82, female: 189). They visited the website for apparel shopping and, after searching a casual clothing which they wanted to buy, requested to answer the questionnaire. The results were as follows: Variables that reduce validity were deleted in the several steps of factor analysis and initial measurement model testing. Final measurement model was constructed by valid variables was accepted. This measurement model will be input for testing causal research model that can explain how attributes of the website influences on consumer attitude toward the website.

  • Legibility of electronic paper was evaluated by using the method of letter-search task and subjective visual comfort scaling. The results show that legibility depends on the illumination level, and conventional paper has a higher visual comfort rating than electronic paper although they have the similar performance in the letter-search task.

  • 주의(attention)를 어떻게 할당하는가는 정신물리학뿐만 아니라, 컴퓨터 시각과정을 모델링하는데 중요한 주제 중 하나이다. 기존 연구는 saliency와 같은 활성화 값에 의해서 주의탐사 순위가 결정된다. 본 논문에서는 주의탐사과정을 병렬처리를 통한 활성화 값 추출과정과 순차적 처리를 통한 공간적 전략과정으로 구분하였다. 단서패러다임에 기초한 계산모형을 이용하여, 실제 인간의 수행결과를 AUC와 Levenshtein 척도를 이용하여 비교하였다. Fixation point 비교에서는 인간과 활성화를 기반으로 한 계산모형의 수행은 높은 상관성을 가지고 있었다. 주의궤적 혹은 scanpath 분석에서는 활성화기반 전략보다는 공간적 전략 모형이 더 높은 유사성을 보였다. 이는 주의탐사과정이 병렬처리과정을 통해 얻어진 saliency에 의해서만 결정되는 것이 아니라, 목표물간의 근접성 등의 공간적 전략을 통해 순차적 (sequential) 경로가 생성됨을 의미한다.

  • The list of the titles of surveying-related papers and books is updated by adding newly polished paper/book titles to the existing one. A special title-search program is developed for managing and searching the surveying-re-lated paper/book titles, and the database is established from the list of the papers. The total number of papers/books in surveying-related field published in Korea upto now is 971. The number of papers/books published in the specific fields are 206 in the conventional surveying field, 218 in Photogrammetry, 183 in Remote Sensing, 127 in Geodesy and GPS, and 237 in Digital Mapping and GIS. The special title-search program is developed using the Visual Basic 3.0 for Windows 3.1 to be operated in the Window environment. The SQL(Structured Query Language) is used for the searching commands.

  • A 3D game plays in fast screen conversion and the objects a partner with camera visual field. Shall recognize a threat of the opponent objects that there is not to a visual field of a player in on-line games. In this paper, we proposed a method to efficiently search for the object in 3D game as used modified frustum culling. For the objects which a player cannot perceive, we accord the player and camera position and used a distance of the player and objects for count of the threatening objects. The method that proposed will play an important role in development of a 3D FPS games.

  • A general process of electronic assembly is composed of a series of geometric alignments and bonding/screwing processes. After assembly, the function is tested in a following process of inspection. However, assembly of micro-optic devices requires both processes to be performed in equipment. Coarse geometric alignment is made by using vision and optical function is improved by the following fine motion based on feedback of tunable laser interferometer. The general system is composed of a precision robot system for 3D assembly, a 3D vision guided system for geometric alignment and an optical feedback system with a tunable laser. In this study, we propose a new fast alignment algorithm of micro-optic devices for both of visual and optical alignments. The main goal is to find a fastest alignment process and algorithms with state-of-the-art technology. We propose a new approach with an optimal sequence of processes, a visual alignment algorithm and a search algorithm for an optimal optical alignment. A system is designed to show the effectiveness and efficiency of the proposed method.

  • The purpose of this study identifies how attributes of the website influences on consumer attitude toward the website. For this purpose, the study tested covariance structural model which set relationships among independent variables(interactivity, search and visual information of website), mediated variables(utilitarian shopping value and hedonic shopping value) and dependent variables(attitude toward website). The data were collected from a sample of 271 internet shopper of university students(male: 82, female: 189). They visited the website for apparel shopping and, after searching a casual clothing which they wanted to buy, requested to answer the questionnaire. The covariance structural model and research hypothesis analyzed by using AMOS 4.0 program. The results are as follows: First, the structural model is accepted significantly. Second, interactivity of the website has a positive impact on perceived utilitarian and hedonic shopping values of the website and visual information of the website also influence hedonic shopping value of the website positively. Third, utilitarian and hedonic shopping values have a positive influence on attitude toward the website for apparel shopping.

  • Objective: The purpose of this study was to investigate the differences between visual search, eye fixation positions, and eye fixation position on whole body regions while judging final matches of dance sports. Method: Ten experienced judges (male 6, female 4) and six dance sports couples belonging to the top Korean leagues in the Korea Dance sports Federation were participated. Wearable eye trackers were used for data collection. The independent t-test was conducted to examine the effects of gender, and the two-way ANOVA was conducted to examine the effects of judges' gender, dance event, and ranking. Results: It was found that the movement of male contestants was preferred, and the gaze fixation was high for torso movements in the judges' evaluations. Moreover, attention was focused on the upper body rather than the lower body; this was maintained for about seven seconds to evaluate each couple. Conclusion: This find was the relative comparison between the two couples was the determining factor in winning or losing.
