This paper aims at the construction of the system that outputs subjective and consistent linguistic expressions of some pictures. Input to this system is information on some pictures and this system outputs explanations of basic contents of pictures and consistent connective relationships between pictures. The present system consists of the explaining part of basic contents and the explaining part of connective relationship. The former part explains behaviors and feelings of objects drawn in pictures. The latter one explains the matters not drawn in pictures by guessing them from pictures. This part considers consistency of connective relationships. From the viewpoint that the interpretation of pictures is dependent on individual subjectivity, the present system has individual database for individual subjectivity. In order to confirm the usefulness of the present approach, simulation experiments are performed. In the experiments the individual databases of subjects are constructed and the outputs of the system are evaluated. Experiment results show that good evaluation is obtained.

A motion compression method by min s-norm composite fuzzy relational equations (dual-MCF) is proposed, where a motion sequence is divided into intra-pictures (I-pictures) and predictive-pictures (P-pictures). The I-pictures and the P-pictures are compressed by using uniform coders and non-uniform coders, respectively. A design method of non-uniform coders is proposed to perform an efficient compression and reconstruction of the P-pictures, based on the dual overlap level of fuzzy sets and a fuzzy equalization. An experiment using 10 P-pictures confirms that the root means square errors of the proposed method is decreased to 82.9％ of that of the uniform coders, under the condition that the compression rate is 0.0055. An experiment of motion compression and reconstruction is also presented to confirm the effectiveness of the dual-MCF based on the non-uniform coders.

최근 소규모화 된 가족 형태는 자녀의 사진을 가족들과 공유하는 행태에도 많은 영향을 미치고 있다. 주로 스마트폰을 이용하여 촬영하고, SNS나 문자 메시지를 통해 가족들 사이에 아이 사진을 공유하거나 모바일 커뮤니티 개념의 공간에 자녀 사진을 올려 공유하는 행태가 두드러지고 있다. 이렇듯 스마트폰을 이용한 사진 촬영과 공유가 급격히 늘어나고 있지만 문자 메시지나 SNS를 통해 사진을 주고받을 경우 백일이나 돌잔치처럼 가족 구성원들이 각각 사진을 찍는 이벤트 발생 시, 다양한 아이의 사진을 일일이 서로 전달하기가 어렵기 때문에 사진을 한데 모아서 보는 것이 어렵게 된다. 또한 출처가 제각각이므로 사진 관리가 어렵다는 문제점이 발생하게 된다. 본 연구에서는 이러한 문제점을 해결하고자 스마트폰을 이용하여 가족 구성원이 각각 찍은 사진들을 특정한 공간에 모아 간편하게 정리하고, 가족구성원이 직접 참여하여 모바일 앨범을 제작하는데 최적화된 UI를 제안하였다.

본 논문에서는 영상을 다중 해상도로 표현하는 직교 웨이브렛변환에서, 비밀스럽게 서명데이터를 영상에 삽입하는 방법을 제안한다. 그 원리는 영상의 다중해상도표현에 있어서 차분출력에 편중(집중)이 있음에 주목하여, 그 특징을 이용하여 서명비트계열을 화상에 삽입한다. 이 때, $256{\times}256$화소로 되는 농담화상으로 대략 6K바이트 정도의 문자정보를 합성할 수 있다. 이 방법은 영상의 저작권을 표시하는 서명데이터뿐만 아니라, 영상의 저자나 사용조건, 또는 영상 그 자체의 속성정보를 포함할 수 있어, 영상데이터베이스의 검색 등에 있어서도 유사영상의 식별을 용이하게 할 수 있는 등의 응용을 고려할 수 있다.

This study investigated the characteristics of science imaginary pictures drawn by elementary school students and their perceptions of science imaginary drawing. To do this, $5^{th}$ graders (N=107) were selected from 1 elementary school in Gangwon province and were administered the questionnaires. Some of them were also interviewed deeply. The analyses of the results indicated that most students drew science imaginary pictures in 'land' or 'universe' of 'future' than non-science imaginary pictures. In the academic field, 'machine' was most frequently included in their pictures, and 'earth science' or 'building and traffic' was also frequently included. In addition, half of the pictures included two or more fields. Many students perceived positively the educational benefits of science imaginary drawing upon cognitive, affective, and aesthetic aspects. However, they also had several difficulties in the processes of scientific imaginary drawing such as 'difficulties in using artistic skills', 'difficulties in selecting the subject', 'difficulties in imagining', and 'difficulties in expressing my thoughts to pictures'. Educational implications of these findings are discussed.

This article is about the study on pictures of Daoist exercises described in Euibangyoochi- which is the largest book in Joseon Dynasty. Daoist exercises are the active exercises to prevent disease by training their body. In Euibangyoochi, there are lots of information of Daoist exercises. Specially, pictures of Daoist exercises are from '$q{\acute{u}}xi{\bar{a}}nhu{\acute{o}}r{\acute{e}}$nxīnf$\bar{a}$ng'. There are movements of body, methods of respiration, tooth brushing, and hand clapping in Daoist exercises this book. On the other hand, the pictures of Daoist exercises were composed with simple explanations so that readers actually might follow the directions at ease. There are 8 pictures of Daoist exercises left in Euibangyoochi. Those are Daoist exercises tradition in the midium of Joseon Dynasty which led to Hwalinshimbang of Yi-hwang. Also with the trend of preventing disease in these days, the importance of Daoist exercises is emphasized and these pictures became a tool of teaching the old Daoist exercises.

As there is a growing tendency to represent the 3D content instead of the 2D content, researches for the stereoscopic image and video are under way in a variety of fields such as acquisition compression, transmission, authoring and display. The authoring technique for stereoscopic contents has given emphasis to virtual stereoscopic contents. Thus the authoring technique for stereoscopic pictures is insufficient. When we compose a stereo scene with stereoscopic pictures, stereoscopic contents may not match the stereo scene because each stereoscopic picture may have different camera condition. To solve this problem, stereoscopic pictures have been modified manually. It is a laborious work and will be spent much time. Also it is difficult for a user who does not have an elementary knowledge of stereopsis. In this paper, we propose the synthesis method to compose a natural stereo scene with stereoscopic still pictures and moving pictures. Experimental results show that the proposed method in this paper allows a user to synthesize stereoscopic contents easily and compose a stereo scene conveniently.

New year pictures prevailed from 1660s to 1860. Especially, the reign period of Emperor Qianlong(r. 1736-1795) was the period of prosperity. The period of 1660s when new year pictures were started to be popular was the reign period of Emperor Kangxi(r. 1662-1722) was just started and corresponded to Emperor Kangxi's promulgation of "Sacred Edict." Chinese operas such as Peking opera were very popular among common people in the period from 1660s to 1860 when new year pictures prevailed. Qing emperors as foreign ruler chose the way of ruling their people by means of cultural influence in stead of military power. However their culture effort was not efficient toward the majority of illiterate people. New year pictures offered every information about the world through visual icons to the illiterate people at that time who perceived the world by means of seeing. They met the world through visual information offered by new year pictures. New year pictures were the stronger visual medium to spread and educate "Sacred Edict" to illiterate subjects than any other guide books published by elite officers.

목 적 : 본 연구의 목적은 한국인에게 적합한 사회적 정서를 유발하는 자극(한국형 사회적 정서 유발 시각 자극, Korean Social Affective Visual Stimuli, K-SAVS)을 개발하는 것이다. 방 법 : K-SAVS는 극동 아시아인이 등장하는 사회적 상황의 사진들로 구성되었다. 각 사진은 부정적 정서 자극, 긍정적 정서 자극, 혹은 중립 자극으로 구성하였다. 24명의 피험자에게 긍정적 자극과 부정적 자극을 보여주고 정서가 및 각성수준에 대한 자가 평가 마네킹 척도를 작성하게 한 후, 다른 24명의 피험자들에게 부정적 자극과 중립 자극을 보여주고 같은 척도를 작성하게 하였다. 결 과 : 1차 실험에서 95개의 자극 사진 중 긍정적 정서자극 사진 1개 세트, 부정적 정서 자극 사진 2개 세트를 선정하였다. 각 세트는 18개의 사진으로 이루어졌다. 긍정적 정서 자극은 부정적 정사 자극 사진에 비해 호감도는 높았으며 (p < 0.001) 흥분도는 낮았다(p < 0.001). 2차 실험에서는 1차 선정된 사진들과 중립 자극 사진을 포함하여 79개의 사진 중 중립 자극 사진 1개 세트를 선정하였다. 중립 자극은 호감도는 높았으며(p < 0.001) 흥분도는 낮았다(p < 0.001). 결 론 : K-SAVS는 한국인에게 특정한 사회적 정서를 유발하는데 유용하게 사용할 수 있는 시각 자극이라 할 수 있다.

The authoring technique in 3D stereoscopic technology has dealt in virtual stereoscopic contents. Thus authoring technique for stereoscopic pictures is insufficient. In this paper, we propose the method for authoring stereo scenes with a stereoscopic still picture and moving pictures. And there are no standards for stereoscopic contents in MPEG-4 systems. Thus we propose the extended MPEG-4 systems to support an interactive service with stereoscopic contents. We define new nodes for stereoscopic contents.
