본 논문에서는 최근 지상파 방송사의 아카이브 개방·공유 사업이 활발해짐에 따라 방송사 외부 이용자들의 방송·영상아카이브 콘텐츠 수요를 연구하였다. 방송사가 개방한 영상자료를 활용해 2차 저작물을 제작하는 과정에서 이용자가 영상자료를 선택하는 기준, 편집에 활용되는 과정 등을 연구하였다. 이를 위해 2022년 KBS가 자사 5.18영상자료를 공개하고 이를 활용해 시청자들에게 새로운 콘텐츠를 제작하게 했던 '5.18 아카이브 시민공유 프로젝트 5월이야기' 공모전을 사례로 살펴 보았다. 해당 공모전에서 우수작으로 선정된 작품을 분석하고 각 작품을 제작한 수상자들과 심층인터뷰를 진행했다. 그 결과 다음과 같은 점을 확인할 수 있었다. 공모전 출품작 중에는 직·간접적으로 5.18 민주화운동을 경험한 내용을 다루면서 해당 역사적 사건이 개인과 현재 우리 사회에 미치는 영향에 주목한 주제를 구성한 작품이 많았다. 방송사가 소장자료 일부를 일반에 공개한다는 사실만으로도 방송사 외부 이용자들에게는 새로운 콘텐츠를 창작해보고자 하는 제작동기를 갖게 하고, 새로운 주제를 구상할 수 있게 함을 알 수 있었다. 또한 이 연구에서는 방송사 영상자료가 2차 저작물에서 활용되는 방식을 살펴보았다. 영상자료를 매개로 하여 역사적 사건을 공유하거나, 영상자료를 증거 또는 비유로서 제시하는 방식을 확인했다. 방송사가 영상자료를 제공하는 데 있어서 5.18 민주화운동 등과 같은 공공성 있는 영상자료가 더 다양하게 개방되어야 한다는 점, 선별된 영상을 공개하기에 앞서 저작권 정보 등을 포함한 메타데이터 정리, 실제 편집에 활용 가능한 고화질·고음질 영상 확보, 이용자 편의성을 고려한 스트리밍 또는 다운로드 기능 강화 등이 필요하다는 점을 확인했다. 이를 통해 향후 지상파 방송사의 영상자료 개방·공유사업의 방향을 모색하고 방송사의 아카이브 사업이 영상자료를 매개로 한 지역·세대·계층 간 사회통합 강화 등 공적 책무를 이행하는 대안이 될 수 있음을 확인했다.

With Unity creating footage is possible by using 3D motion, 2D motion, particular, and sound. Even post-production video editing is possible by combining the footage. In particular, Cinemachine, a suite of camera tools for Unity, that greatly affects screen layout and the flow of video images, can implement most of the functions of a physical camera. Visual aesthetics can be achieved through it. However, as it is a part of a game engine. Thus, the understanding of the game engine should come first. Also doubts may arise as to how similar it is to a physical camera. Accordingly, the purpose of this study is to examine the advantages and cautions of virtual cameras in Cinemachine, and explore the potential for development by implementing storytelling directly.

There has been an increase in video surveillance for public safety and security, which increases the video data, leading to analysis, and storage issues. Furthermore, most surveillance videos contain an empty frame of hours of video footage; thus, extracting useful information is crucial. The prominent framework used in surveillance for efficient storage and analysis is video synopsis. However, the existing video synopsis procedure is not applicable for creating an abnormal object-based synopsis. Therefore, we proposed a lightweight synopsis methodology that initially detects and extracts abnormal foreground objects and their respective backgrounds, which is stitched to construct a synopsis.

Charles Stankievech's 2011 installation LOVELAND includes a wall-sized screen depicting video footage of a barren arctic landscape in an enclosed room, painted and bathed in white light, that appears as an extension of the imaged environment. A melodic and industrial musical score emanates from multiple sound panels and as the music increases a cloud of purple smoke becomes visible on the horizon line in the distance and gradually advances toward the viewer until it completely fills the screen. The smoke then remains, rushing about madly and lapping at the border between the screen and the room before it suddenly subsides and the spectator is again left with the desolate landscape. The entire process takes a mere five minutes and then, fixed on an endless loop, begins again. This paper positions LOVELAND as an attempt to simulate a sublime experience of the end of the world through a transposition of the Arctic atmosphere into the gallery space. Encompassing a discussion of the historical and contemporary significance of the Arctic in popular culture, aesthetics and environmental politics, it is suggested that Stankievech employs an apocalyptic trope in reference to the unstable position of the North in the current political and ecological climate. Revisiting critiques of modernist exhibition practices and investigating the perceptual and temporal dimensions of the work, this analysis focuses primarily on the experience of the installation's spectator. Visually, aurally and phenomenologically immersed, the viewer is made subject to, and implicated in, the events unfolding on the screen and within the space. Due to the looping of the video footage, this paper argues that the apocalypse imaged in LOVELAND is presented as an endless event - incessantly enacted, yet infinitely deferred - and that the spectator is enveloped in an uncertain and unceasingly extended present moment.

Standard open procedures for resection of the first rib in thoracic outlet syndrome can prove to be quite difficult with extensive incisions. A minimal invasive procedure can also be painstaking, but provides an attractive alternative to the more radical open procedures. We report the details of the technique with direct video footage of the procedure performed in a 41-year-old man with thoracic outlet syndrome done entirely by thoracoscopic methods.

The behavior of angelfish Pterophyllum scalare exposed to low and high temperatures was monitored by video tracking, and information such as the initial speed, changes in speed, and locations of the fish in the tank were analyzed. The water temperature was raised from 26℃ to 36℃ or lowered from 26℃ to 16℃ for 4 h. The control group was maintained at 26℃ for 8 h. The experiment was repeated five times for each group. Machine learning analysis comprising a long short-term memory model was used to train and test the behavioral data (80 s) after pre-processing. Results showed that when the water temperature changed to 36℃ or 16℃, the average speed, changes in speed and fractal dimension value were significantly lower than those in the control group. Machine learning analysis revealed that the accuracy of 80-s video footage data was 87.4%. The machine learning used in this study could distinguish between the optimal temperature group and changing temperature groups with specificity and sensitivity percentages of 86.9% and 87.4%, respectively. Therefore, video tracking technology can be used to effectively analyze fish behavior. In addition, it can be used as an early warning system for fish health in aquariums and fish farms.

본 연구에서는 농구부 지도자들이 촬영한 농구 학생 선수들의 슈팅 훈련 영상을 바탕으로 슈팅의 투사각도를 분석하였다. 슛팅 영상에서 스크린 샷을 통하여 선수의 슈팅한 높이와 공의 궤적을 실선을 통하여 그렸고, 이를 선수들에게 보여주어 성공률이 더 높은 상황으로 투사각도를 조절할 수 있도록 지도하였다. 본 연구를 통하여 영상을 통하여 농구선수들에게 효율적인 지도가 가능할 수 있다는 것을 알 수 있었다.

This study attempted to analyze human brain responses toward visual content through EEG signals and intended to measure brain wave reactions of different age groups to determine the sexuality level of the media. The experimental stimuli consist of three different video footage (rated ages 12, 15, and 18) to analyze how subjects react in situations where they actually watch sexual content. For measuring and analyzing brain wave reactions, EEG equipment records alpha, beta, and gamma wave responses of the subjects' left and right frontal lobes, temporal lobes, and occipital lobes. The subjects of this study were 28 total and they are divided into two groups. The experiment configures a sexual content classification scale with age or gender as a discriminating variable and brain region-specific response frequencies (left/right, frontal/temporal/occipital, alpha/beta/gamma waves) as independent variables. The experimental results showed the possibility of distinguishing gender and age differences. The apparent differences in brain wave response areas and bands among high school girls, high school boys, and college students are found. Using these brain wave response data, this study explored the potential of developing algorithm for measurement of age-specific responses to sexual content and apply it as a film rating.

IT산업의 가속화로 인하여 다양한 미디어 환경이 조성되고 있는 현대사회에 3D-TV 등의 실시간 영상화면은 매우 중요한 이슈이다. 이러한 고화질의 실시간 영상은 매우 다양한 분야에 적용되고 있으며 CCTV 등의 영상 성능에 중요한 파라미터가 되고 있다. 그러나 이러한 고화질의 영상이라도 보안에 취약한 단점이 있기 때문에 보안채널 또는 각종 보안 알고리즘을 이용하여 이러한 단점을 없애고자 하는 시도가 매우 활발히 진행 중에 있다. 본 연구에서는 이러한 단점을 별도의 보안기술을 부가하여 처리속도를 감소시키는 것이 아니라 영상처리 자체에 보안기능을 부가함으로서 실시간 처리 및 보안성을 증대시키기 위한 방안을 제시한다.
