TheReviser is a digital document revision application on a projection display, which allows us to interact a digital document with the same gestures used for paper documents revision. To enable these interactions, TheReviser should detect foreground objects such as hands or pens on a projection display, and should spot and recognize gesture commands from continuous movements of a user. To detect foreground objects from a complex background in various lighting conditions, we perform geometry and color calibration between a captured image and a frame buffer image. TheReviser uses an HMM-based gesture recognition method Experimental results show that the proposed application recognizes user's gestures on average 93.22% in test gesture sequences.

Purpose: Basic design of virtual colored overlay, film overlay, colored lenses and colored glasses for people with Scotopic Sensitivity Syndrome. Methods: I calculated sRGB and RGB values of the overlays from measured data. I evaluated the relationship between the combinational chromaticities composed of Galaxy Tab white background and film overlays and the chromaticities of pure film overlays. Results: Implementable sRGB and RGB values of the overlays is calculated. The chromaticities of film overlays are different from them with white paper background and them with Galaxy Tab's white background, but showed a certain relationship between them. Light transmittances of Intuitive Overlay are the most (59%-79%) among them and average light reflectance of Reading Ruler is least(8%). Conclusions: The sRGB values and the RGB values are directly applicable to implement assistive tools and the light transmittances are used to calculate ${\alpha}$, transparency of virtual overlay in IT devices. It is recommended to consider the chromaticity of white color in implementing virtual colored overlay in the case which the chromaticity is considerably different to theoretical chromaticity of white color.

Korea DMB Service is popularized, and is used by many users. But latest display devices compared to the DMB content resolution support higher resolution and a variety of video resampling technologies has been used. Generally, subjective video quality is determined by object recognition rate in video, and increased as the edge space between objects are more clear. An edge is the boundary between an object and the background, and indicates the boundary between overlapping objects. the predicted direction in intra prediction used in H.264/AVC has the similarity up to 80% for the edge information. In the study, we propose an effective up-sampling mothed using the edge information that is extracted for the relationship between the intra prediction data and the DCT coefficient data of H.264 video encoding.

In recent years, the reader of comics get a chance to contact as well as korean comics, and foreign comics has increased to visibly. There was a relatively important progress also on international scale for mutual exchanges, but a variety of ways for the exposure of foreign comics can't help the reader to read easily the foreign comics. Socio-cultural differences also affects the choice of material, but it affects the format more fundamental. Format differences appear most, can be seen in the difference in narrative approach and medium (the book or the digital screen). This Article deals with two different comics, French and Korean comics. French comic is understood as other forms of literature, but the Korean is considered as a multi-media medium. This difference begins with cultural differences dealing with comics. It is also because the nature of the comics called hinge between the multi-media culture and culture of the books. This study will focus on the differences between the French comics which defend the value of the book and Korean Webtoons which suggest a new way in the digital environment. Through their differences, we can recognize the power of comics and can also predict its development in different medium.

This study analysed motion graphic formative image composition of TV LED backdrop to be used as background display for performers such as singers appeared on TV music show. Motion graphic LED images are comprised of various plane figures, and backdrop's design function as background screen has a goal to convey synesthesia and sensibility of visual elements. And this analyse classified sensibility concept about color, motion direction and speed to be elements of transmitting sensibility. As the analyse of graphic form among transmitting sensibility elements, this classified form type into its' applied elements, and studied how these elements' motion pattern and arrangement could be placed and replaced at song's four step composition, intro, verse, bridge, chorus part, and also characterized differences of backdrop design for male and female performers. As a case study, it included terrestial broadcasting TV song ranking shows targeted at teenagers. Because they carried out various motion design utilizations. Finally, this reasoned out mainly designing form type, its' applied elements, motion pattern and its' arrangements type division according to the song developing four steps.

In this study, I examined the visual elements for narrative structure and the symbols, scene components and visual styles in the images through analyze the flat staging in Tomm Moore's animated feature film, . As a research method, I figure out the general theories about staging and analyze extracted scenes which revealed flat staging in the , then summarize and clarify the flat staging production elements and features of Tomm Moore. As a result, in , the composition of the screen using the basic shapes, the screen composition containing the spiral which is symbol of the Celtic traditional pattern, the stable and flat frame expression through the balanced screen composition, expression of spatial sensation using perspective, appearance of the period by using the inverted perspective, and composition that can emphasize the flat formability are appeared as a characteristic. Through this, the two-dimensional planarity was maximized to convey the feeling of appreciating the illustrations of fairy tales. Tomm Moore, who produced animation based on folk tales in order to inherit the traditional culture of Ireland, has been attracting worldwide attention because of its flat staging to help narrative, enhancing the original expression and performance of animation. I hope that this study will be used as basic data for industry workers and researchers who make unique and excellent animated feature film.

연구 주제는 우리 모두가 성자하면서 느끼고 경험했을, 그러나 고단한 일상 속에 파묻혀 잊고 지냈을, 유년시절의 이야기를 조그마한 시골지역을 비경으로 잔잔하게 그려내는 데 초점을 맞추었다. 도시에서 이사온 한 초등학생에게 시골마을은 제대로 포장된 도로도, 이층집도 없는 곳이었지만 주변에는 친구들과 뛰어 놀기에 부족함이 없는 경이로움으로 가득 찬 곳이었다. 이때의 느낌과 에피소드가 여러 장면 속에 봄부터 겨울까지 일년 사계절을 배경으로 담겨져 있다. 이런 의도 속에서 각 그림의 주제와 등장인물간의 조화를 맞추며, 각각의 그림은 개별적으로 독립적인 이야기를 담고 있으면서도 전체적으로 서로 연관된 고향이라는 주제의 하나의 이야기이다. 독특한 표현세계의 추구를 위한 기법연구로 한국화 기법을 만화와 접목을 통해 동양적인 정서와 회화적인 표현이 접목된 만화를 연구함으로써, 대중성과 예술성이 보완된 작품을 시도하고자 하였다. 과정 속에서 본인은 전형적인 우리나라 시골 어린이들의 생생한 감정과 동작의 움직임, 각가지 얼굴표정과 제스처를 만화적인 기법으로 표현하고자 하였으며, 한편으로는 그림의 배경이 되는 우리의 자연과 산하를 동양화 기법으로 특징을 잡아내고자 노력하였다. 이와 함께 독자의 이해를 높이기 위해 매 장면마다 그에맞는 이야기를 나레이션 형식으로 삽입하여 평면 작품으로 제작하였고, 또한 그 작품을 CD-ROM 속에 담음으로써 영상화된 화면에서 제작하고자 하였다. 이번 작품 제작을 통하여 본인의 의식 깊은 곳에 영향을 주고, 낳고 키워준 고향의 이야기들을 표현함으로 본인을 포함한 도시생활에 찌들어 있는 현대 대중들에게 위로와 휴식을 줄 수 있는 작품이 되고자 노력하였다.
