본 논문에서는 비대칭적 화질을 갖는 스테레오스코픽 영상에서 화질개선을 위해 사용되는 부가정보를 효율적으로 부호화하기위한 방안을 제안한다. 부가정보의 대부분은 좌영상과 우영상의 높은 상관도를 기반으로 하는 양안시차 벡터맵으로 구성되며, 이것을 부호화하기 위해 분포 특성을 분석하였고, 이에 맞는 엔트로피 부호화 방식인 지수 골롬 부호를 적용하였다. 또한, 양안시차 벡터맵의 공간적 데이터의 중복성을 없애기 위해 DPCM을 적용하여 부호화의 효율성을 높였다.

The purpose of this study is to analyze the difference of the visual perception and attention of the people with intellectual disability from the application of the assessment applying an electronic media and traditional paper material. The study subjects were 12 people with intellectual disability, To assess the visual perception, the motor free visual perception test-3 was used and the trail making test was used to assess the visual attention. After the assessment of the visual perception and attention applying the traditional paper material, the assessment applying the electronic media. The results of the visual perception and attention showed the difference of the visual perception and attention, and the scores of the visual perception and attention applying the assessment of the electronic media showed the more higher than the assessment of the traditional paper material. The electronic media could be worked as a factor to increase the visual perception and attention of the people with intellectual disability. Thus, the difference should be considered to apply the electronic media for them.

In this paper, a synthesis method for the desired scattering pattern is presented when illuminating by TE-polarized and TM-polarized plane waves to arbitrary dielectric material. It is considered that the one-dimensional dielectric media are inhomogeneously distributed with continuously varying dielectric constants. Accordingly the desired patterns and the corresponding source distributions are inversely transformed by the proposed algorithm which are based on the one-dimensional inverse scattering problem. Some bandstop spatial filter are illustrated for applications.

The wearable computer that can understand the context of human life and intelligently communicate with various electronic media in ubiquitous computing environment would be very useful as an assistant for humans. In this paper we introduce an intelligent wearable assistance suite. The proposed wearable suite can interact with both humans and electronic media in ubiquitous computing environment. The developed system can sense the interactive electronic media that a user wants to use and also communicate with it. By utilizing these interaction capabilities, it intermediates between each media and the user and offers a friendlier interface to the user who wears this system. We also show the usages of the proposed system by demonstrating its interaction with the interactive electronic media in ubiquitous computing environment.

Deep learning has made rapid progress in recent years and is affecting various fields and industries. The art field cannot be an exception, and in this paper, we would like to explore and experiment and analyze research fields that creatively generate 2D images in 3D from a visual arts and engineering perspective. To this end, the original image of the domestic artist is learned through GAN or Diffusion Models, and then converted into 3D using 3D conversion software and deep learning. And we compare the results with prior algorithms. After that, we will analyze the problems and improvements of 2D to 3D creative generation.

최근 스마트폰의 사용이 보편화 되고 주요 소비층이 밀레니엄 세대가 됨에 따라 개인 방송이 큰 이슈로 떠오르고 있다. 개인 방송 서비스 중 최근 큰 인기를 끌고 있으며 많은 사용자를 확보하고 있는 것이 게임 방송 분야이다. 게임 방송을 진행하는 브로드캐스터는 스트리밍 영상과 채팅을 통해 시청자와 실시간으로 소통하며 방송을 진행한다. 하지만 시청자는 브로드캐스터의 목소리와 화면에만 의존할 뿐 다른 추가적인 정보 서비스를 제공받기에는 한계가 있다. 이에 본 논문은 OBS를 이용한 HTML5 기반, JQuery 웹소켓 프로토콜을 통해 개인 방송 플랫폼을 제작하였고 Socket.IO를 사용하여 실시간 채팅 서비스를 추가하였다. 방송을 송출하는 방송 진행자가 입력하는 키 값을 스트리밍 영상에 오버레이할 수 있게 됨으로써 시청자에게 게임 진행 정보를 전달할 수 있고 시청자는 이를 통해 방송 진행자의 게임 스킬을 습득할 수 있으며 몰입감을 높일 수 있는 서비스를 개발하였다.

하이라이트 영상은 원본 영상의 중요한 장면들을 짧은 시간 안에 감상할 수 있게 도와준다. 특히나 경기 시간 긴 축구나 야구 그리고 e-스포츠의 시청자들에게 있어, 하이라이트 영상의 효용성은 더욱 증가한다. 하이라이트 영상 추출의 자동화로 방송사나 온라인 플랫폼은 비용 절감과 시간 절약의 이점을 얻을 수 있다. 따라서 본 논문에서는 스포츠 영상에서 자동으로 하이라이트 구간을 추출하는 모델을 제안한다. 제안하는 모델은 멀티 헤드 어텐션 매커니즘과 LSTM 네트워크의 결합으로 구성된다. 해당 매커니즘의 여러 헤드를 통해 어텐션을 다양한 관점에서 진행한다. 이로 인해 영상의 전체적인 맥락과 장면 간의 유기적 관계를 다양한 관점에서 파악할 수 있다. 또한 오디오와 이미지 정보를 함께 이용하여 모델을 학습한다. 학습한 모델의 평가는 e-스포츠 경기 영상을 이용하여 평가한다.

COVID-19 pandemic has affected the lives of people and has forced businesses to develop different ways of doing businesses. Several businesses have implemented social responsibility activities. With social distancing keeping many people at home, online and digital platforms have become one of the most important mechanisms for businesses undertakings and implementing those social responsibility initiatives and activities - digital social responsibility (DSR). The purpose of this study is to examine the relationships of electronic word-of-mouth (eWOM) intentions and customer engagement with DSR in social media with attitude toward DSR as the antecedent during COVID-19 social distancing situation in Thailand. The study employs a quantitative research method where sampling method is followed by convenience sampling technique, and study data is collected through survey questionnaire with social media users who have experiences with firms' online social responsibility initiatives. Based the samples of 123 respondents, Structural Equation Modelling (SEM) has been used for analysis. The results show that attitudes toward DSR in social media significantly influence electronic word-of-mouth (eWOM) intentions and have a significant effect on customer engagement with DSR in social media. The mediation analysis also revealed that eWOM intention partially mediated the relation between attitudes toward DSR in social media and customer engagement.

Today's media environment is becoming very complicated and the trend of media convergence is getting clearer. The convergence of media is the supreme hot issue. In this wave of convergence, there has also been a huge change between movies and electronic games. The remake boom between them showed a tremendous economic effect that can be achieved by exchanging two media of essentially different characteristics. As computer virtual reality technologies evolve, electronic games will provide a virtual world that can satisfy the demands of the visual, auditory, and tactile aspects very real to the public with the Internet. At that time, movies and other media will be thoroughly melted into the virtual world created by electronic games, and they will become an element of the virtual world as those media that exist in the truth world.
