The influence of digital media according to environmental change of multi-media came to have significance more than what we imagine. In accordance with high resolution of HDTV in digital media era, the cautious awareness is required for skin color by the immediate color such as replica of TV color, lighting and clothing. As for the broadcasting makeup expression technique caused by a change in broadcasting environment in the digital media era, the first, There is necessity for natural makeup technique, and for expressing the whole makeup evenly and very delicately. The makeup work gets much more delicate. For the delicate expression, more time is being required than the existing makeup time. Second, Lots of time and manpower are required for elaborate real-object processing on all the production fields such as background set, stage properties, and makeup. Third, Realistic expression is available on the screen. Importance of basic makeup is highlighted. Thus, even the skin care shop came to be prevalent. Development in only HD cosmetics is needed for foundation with fine particle in new material and with diverse colors hereafter. The video-media field is a method that is ignored a sense of distance through vehicles such as camera, picture tube, and several kinds of broadcasting machinery and equipment and that is delivered vividly to viewers through screen, unlike the stage makeup, thereby being needed the makeup technology proper for HDTV according to the changing broadcasting environment and media. The video machinery and equipment are proceeding with being gradually high-tech and precise. Thus, an expert in makeup needs to know common sense on the video machinery and equipment before makeup, and needs to make an effort according to it. And, a follow-up research can be said to be necessary on the advance in makeup method and on more diverse dedicated cosmetics along with a research on color tone proper for HDTV.

The purpose of this study was to investigate representation of media on Korean controversial historical incidents and its myth and ideology. Especially the authors paid attention to the MBC-TV Documentary which had dealt with many controversial issues in Korean society. Those issues had never been dealt by other Korean media before it began to do. Three episodes about the South-North Korea related issues were selected as main object of this study and were analyzed with various semiotic research methods, especially, paradigmatic analytical method, narrative analytic method and mythical analytic method. As a main result of this study, it was found that the Documentary tended to represent such controversial historical issues very differently from the previous representations of old newspapers'. Th e old newspapers tried to establish old myths; that is, 'myth of national crisis', 'myth of anti-communism', 'myth of scapegoat of college students', 'myth of intelligent agency's monopoly', 'myth of social stablization', etc, while the documentary changed to build up new myths; that is, 'myth of humanities', 'myth of peaceful unification', 'myth of freedom and democracy', 'myth of human rights, etc.' In short, it was concluded that the documentary was able to change some previous myths and ideologies through its changing representations.

As a form of media diversified and changed by the development of technology, fashion advertisements have brought a new change in representation of the body. With this transition, the characteristics of the body, which is in an inseparable relationship with fashion, have been dramatically changed in fashion advertisements. In hugely extended media flow, fashion advertisements suggest concepts of the body that are completely different from the past and became the focus in advertisements. Moreover, the body in fashion advertisements involve the symbolisms of social and cultural backgrounds followed by their commercialization. This study analyzes the characteristics of the body in fashion advertisements drawing on the innovative concepts of the body in contemporary society which is essentially different from the past ones; these characteristics are examined as postmodern features. The features are categorized as follows; hyperreal body, virtual body, fragmentization of the body through neologism, reconsideration of naked body, and decentralized body. The postmodern characteristics of the body have changed the boundary, broken traditional concepts and thoughts, and proposed new trends by creating revolutions though diversified media. Rapidly changing media is considered to be further accelerated; this transition highlights the postmodern characteristics of the body in fashion advertisements in more innovative methods.

MPEG 4 Part 20 LASeR (ISO/IEC 14496 20) is a specification designed to deliver rich media services in a mobile environment. The specification is an emerging standard that can replace the MPEG 4 BIFS specification designed to deliver PC based heavyweight media contents. The specification describes the representation of scene information in a resource constrained mobile environment. Unlike the BIFS standard designed to deliver heavyweight rich media, the LASeR specification has a restricted description that conforms to the SVG Tiny 1.2 specification. Also, the specification has an advantage of allowing for the efficient conversion of one graphics format to another. In this paper, we present the design and the implementation of a LASeR authoring system that allows for fast and efficient creation of interactive rich media contents in a mobile environment. The Gill interface of the authoring system presented in this paper allows users, who do not have prior knowledge of the scene description language, to conveniently create contents and store the produced scenes using the internal list data structure. The system allows users to navigate scene objects internally stored and to create LASeR XML files in the structured XML format.

Identifying and searching for characters appearing in scenes during multimedia video editing is an arduous and time-consuming process. Applying artificial intelligence to labor-intensive media editing tasks can greatly reduce media production time, improving the creative process efficiency. In this paper, a method is proposed which combines existing artificial intelligence based techniques to automate character recognition and search tasks for video editing. Object detection, face detection, and pose estimation are used for character localization and face recognition and color space analysis are used to extract unique representation information.

In this paper, we introduced a novel voxel-wise UV parameterization and view-dependent texture synthesis for the immersive rendering of a truncated signed distance field (TSDF) scene model. The proposed UV parameterization delegates a precomputed UV map to each voxel using the UV map lookup table and consequently, enabling efficient and high-quality texture mapping without a complex process. By leveraging the convenient UV parameterization, our view-dependent texture synthesis method extracts a set of local texture maps for each voxel from the multiview color images and separates them into a single view-independent diffuse map and a set of weight coefficients for an orthogonal specular map basis. Furthermore, the view-dependent specular maps for an arbitrary view are estimated by combining the specular weights of each source view using the location of the arbitrary and source viewpoints to generate the view-dependent textures for arbitrary views. The experimental results demonstrate that the proposed method effectively synthesizes texture for an arbitrary view, thereby enabling the visualization of view-dependent effects, such as specularity and mirror reflection.

This paper explains about the structure of multiple sensorial media application format (ISO/IEC 23000-17), which is newly standardized as a project of MPEG-A. This format facilitates effective storage, playing, and management of media with multiple sensorial effects. The ISO base media file format from MPEG-4 Part 12 and sensory effect metadata (SEM) from MPEG-V Part 3 are used to composed the multiple sensorial media application format. In this paper, a fragmentation method to break a SEM XML document into valid SEM samples is presented. Several binarization methods to compress the SEM samples are compared and evaluated as well. The compression ratio and processing time using the MPEG-V binary representation and the Binary MPEG format for XML (BiM) are superior to the gzip compression.

In this paper, we propose digital exhibition contents for the aquarium, especially 'Gyeongpo Lagoon Ecological Museum'. We try to plan appropriate media contents that can be mixed with the aquarium storytelling. The aquarium must have special spaces that are not related with an exhibition directly but are necessary for survival of fishes such as a water circulation room. We design the special spaces using media contents and let visitors feel that the whole aquarium is in the ocean. First of all, we investigate the aquarium currently under construction. And then, we propose the appreciate media platforms and plan individual content. We suggest 3 types of media platforms, 3D water projection, interactive games utilizing Kinect, and a fog screen. Moreover, we produce 2D drawing concepts, 3D modeling images, and virtual exhibitions in virtual reality for the representation of the location in which those platforms are installed and the media contents we plan. The pre-visualization is helpful for the media platform construction and is used as a rough sketch to producing an animation shown in the exhibition.

본 논문에서는 영상의 정보량에 따라 영상을 분할하고 이를 바탕으로 영상을 계층적으로 부호화하는 알고리듬을 제안한다. 영상을 분할하기 위해서 4진나무구조를 사용하는데, 기존의 방법에서는 각 구획의 평균값을 대표값으로 사용하여 구획의 복잡도를 판단하고 영상을 복원하는 반면, 본 논문에서는 해당 구획의 모서리 화소값을 대표값으로 사용하는 개선된 알고리듬을 사용한다. 분할된 구획의 대표값으로 모서리화소를 사용함으로써 여러 해상도에서 계층적인 영상표현이 가능하다. 제안방법으로 표현된 영상은 복잡한 신호처리과정이 필요 없으며, 부가적인 후처리기법을 사용하지 않고도 복원 영상에서는 구획화현상이 사라지므로 주관적으로 자연스러우면서도 객관적으로도 우수한 성능을 보인다.
