Pliny the Elder said that multiple cultures agree that the painting began as a shadow trace. A daughter of Butades, the potter in Corinth, traced an outline around a man's shadow, and it was the very beginning of painting. In this anecdote, the profile, i. e. the portrait substitutes body of the absent lover. It makes the absent body present and replaces his place. In this context Hans Belting put the anthropological value to this visual practice. Human being made images to cope actively with the shock of death and the disappearing of body. With the aid of the representation of the bodily presence, the image struggles to resist the death. This paper is a study on the critical meaning of representation in the context of bodily survival by image. The representation is the paradoxical trick of consciousness, an ability to see something as 'there' and 'not there' at the same time. So the connection between image and the body would be suspicious. Although this relation was tight in the ancient shadow painting and the medieval effigies, the modern visual practice forsakes this connection and exposes the trick of representation. It insists that image was not real and even expels the medieval visual practice from the boundary of fine arts. The genealogy of the portraiture is formed by two different visual practices. The belief and the disbelief in the image are observed in the process of representation and anti-representation, and this ambivalence transforms the ontological meaning of portrait in the visual representation.

본 논문에서는 적분 영상(Integral Image)을 이용하여 고속 비디오 안정화를 수행하는 새로운 기법을 제안한다. 제안된 기법에서는 매 프레임마다 적분 영상을 생성하고, 생성된 적분 영상에서 영상의 블록 움직임의 정합을 평가하여 지역 움직임을 추정한다. 이를 사용해서 전역 움직임을 추정하여 보정한다. 제안된 기법의 효율성을 평가하기 실험 데이터를 다양한 패턴으로 직접 제작하였고, 기존 안정화 알고리즘과의 떨림 보정과 수행 시간을 평가하였다. 실험 결과에서 기존 제안한 기법이 기존 방식들에 비해서 수행 시간이 빠르고 떨림을 검출하여 보정함을 확인하였다.

In the 2D local dimmable LED backlight system, each LED segment can be controlled separately. This can enhance the contrast ratio and reduce overall power consumption of LCDs. However, an artifact such as 'halo mura' can be observed around the bright object in the dark background. This is caused by the light leakage from the bright area into the dark one. Therefore, the 'halo mura' can be more easily observed in the oblique viewing direction. Thus, in this study, the perceivable degree of the halo mura is evaluated according to the level of the off-axis light leakage of LCDs. It is found that an acceptable degree of halo mura can be obtained in 2.0 cd/$m^2$ of the diagonal light leakage. In addition, the halo mura is unperceivable under 0.7 cd/$m^2$ of the diagonal light leakage which can be achieved with optimally compensated polarizers.

A number of studies have shown that students have a stereotyped image of a scientist, and this image is often a rather negative. Earlier work on images of the scientist revealed to be consistent across the various social classes and across countries. This study aimed to examine a Korean students' stereotyped images of scientist, compare it with earlier work, and also find out whether students have other ideas about scientist, apart from the stereotyped image. To these purposes, modified DAST and individual interviews were carried out with 217 students and 53 students, respectively. The results are as follows : 1. Most of the students portrayed the scientist as a neat and young man with well-featured face, which was different from earlier studies. 2. Year 3 boys described the scientist as a mu, but year 3 girls as a woman. 3. Most of the students gave positive answers which were at variance with the streotyped image. 4. An interview asking only one question was a complement to DAST. It was concluded that students have private perceptions of scientists and their work, as well as a stereotyped image.

최근 스마트 폰을 이용한 사용자들이 생성하는 사진 데이터의 양이 급속히 증가하였다. 폭발적인 사진 데이터 양의 증가는 사용자가 원하는 사진에 대한 접근을 어렵게 하였다. 때문에 본 연구에서는 사진의 접근 및 관리의 효율을 높이기 위한 폭소노미를 통한 태그 추천 시스템을 안드로이드 모바일 플랫폼과 서버의 연계로 구현하였다. 구현된 애플리케이션은 25,000 장의 사진을 기반으로 하는 폭소노미를 통해 태그 추천을 하며, 태그 추천에 평균적으로 5.5 초의 시간이 걸렸다.

There is substantial evidence from earlier researches that older adults have difficult seeing under low illumination and at night, even in the absence of ocular diseases. During human aging, there is a rampant decrease in rod/cone-meditated adaptation which is caused by delayed rhodopsin regeneration and pigment depletion. This calls for a need to develop appropriate visual gadgets to effectively aid the aging generation. Our research culminates its approach from Pattanaik's model by making extensions to temporal visual filtering, thereby simulating a reduction of visual response which comes with age. Our filtering model paves way and lays a foundation for future research to develop a more effective adaptation model that may be further used in developing visual content adaptation aids and guidelines in MPEG 21 environment. We demonstrate our visual model using a High Dynamic Range image and the experiment results are in conversant with the psychophysical data from previous vision researches.

The purpose of this study is to analysis BTS's image based on Peirce's semiotics. Methodologies of this study are literature study to analyze the structure of idol image based on Peirce's theory of signs, case study and FGI analyzing the semiotic characteristics of BTS images. The research results of analyzing the semiotic features of BTS images by period of the BTS album are as follows. First, in the early days of their debut, they emphasized the image of hip-hop and expressed their will to resist and rebel against the older generation with a challenging and strong image. Second, during the 'The most beautiful day of life' period, image of wandering, rebellion, growth, and youth of teenagers was expressed. Third, in the 'Love Yourself' period, BTS showed various image changes between natural and pure image to splendid image by expressing the process of finding confidence during chaotic moment of growing. Fourth, during the 'Map of the Soul' period, the exploration and reflection on themselves were expressed in an outwardly splendid and bright manner, while at the same time expressing the inner darkness in a contrasting manner. Fifth, in the 'pandemic period', they expressed hopeful energy and willness with the image of mature and attractive man and bright and casual image. Their growth and change have been directly linked to the change of their image, and their image showed a successful signification with complementary combination of icons, indexes, and symbols.

Major deficiencies of current automation scheme including various robots for bioproduction include the lack of task adaptability and real time processing, low job performance for diverse tasks, and the lack of robustness of take results, high system cost, failure of the credit from the operator, and so on. This paper proposed a scheme that could solve the current limitation of task abilities of conventional computer controlled automatic system. The proposed scheme is the man-machine hybrid automation via tele-operation which can handle various bioproduction processes. And it was classified into two categories. One category was the efficient task sharing between operator and CCM(computer controlled machine). The other was the efficient interface between operator and CCM. To realize the proposed concept, task of the object identification and extraction of 3D coordinate of an object was selected. 3D coordinate information was obtained from camera calibration using camera as a measurement device. Two stereo images were obtained by moving a camera certain distance in horizontal direction normal to focal axis and by acquiring two images at different locations. Transformation matrix for camera calibration was obtained via least square error approach using specified 6 known pairs of data points in 2D image and 3D world space. 3D world coordinate was obtained from two sets of image pixel coordinates of both camera images with calibrated transformation matrix. As an interface system between operator and CCM, a touch pad screen mounted on the monitor and remotely captured imaging system were used. Object indication was done by the operator’s finger touch to the captured image using the touch pad screen. A certain size of local image processing area was specified after the touch was made. And image processing was performed with the specified local area to extract desired features of the object. An MS Windows based interface software was developed using Visual C++6.0. The software was developed with four modules such as remote image acquisiton module, task command module, local image processing module and 3D coordinate extraction module. Proposed scheme shoed the feasibility of real time processing, robust and precise object identification, and adaptability of various job and environments though selected sample tasks.
