  • In this paper, a video broadcasting system between a home-server-type device and a mobile device is proposed. The home-server-type device can automatically extract semantic information from video contents, such as news, a soccer match, and a baseball game. The indexing results are utilized to convert the original video contents to a digested or arranged format. From the mobile device, a user can make recording requests to the home-server-type devices and can then watch and navigate recorded video contents in a digested form. The novelty of this study is the actual implementation of the proposed system by combining the actual IT environment that is available with indexing algorithms. The implementation of the system is demonstrated along with experimental results of the automatic video indexing algorithms. The overall performance of the developed system is compared with existing state-of-the-art personal video recording products.

  • Multiview plus depth (MVD) videos are widely used in free-viewpoint TV systems. The best-known technique to determine depth information is based on stereo vision. In this paper, we propose a novel local stereo matching algorithm which is radiometric invariant. The key idea is to use a combined matching cost of intensity and gradient based similarity measure. In addition, we realize an adaptive cost aggregation scheme by constructing an adaptive support window for each pixel, which can solve the boundary and low texture problems. In the disparity refinement process, we propose a four-step post-processing technique to handle outliers and occlusions. Moreover, we conduct stereo reconstruction tests to verify the performance of the algorithm more intuitively. Experimental results show that the proposed method is effective and robust against local radiometric distortion. It has an average error of 5.93% on the Middlebury benchmark and is compatible to the state-of-art local methods.

  • ATSC 방식의 디지털 TV 방송의 수신환경을 분석하기 위해 다양한 채널 환경 분석 시스템이 사용되고 있다. 그러나 기존 장비들은 상용 수신기보다 성능이 떨어져 다중 경로 간섭에 의한 수신기의 수신 불량 현상을 측정하고 분석하기에 어려움이 있다. 이러한 문제점을 해결하기 위해서 상용 DTV 수신 칩세트를 채널 환경 분석 시스템에 직접 이용하는 것을 고려할 수 있다. 일반적으로 상용 DTV 칩세트들은 심볼 주파수로 샘플링된 기저대역의 I (In-phase) 채널 데이터 및 동기 신호들을 제공하므로 측정된 I 채널 데이터를 이용하여 좀 더 정확한 신호 품질 및 채널 신호의 분석을 위해서는 효과적인 Q (Quadrature) 채널 데이터의 추출이 필요하다. 본 논문에서는 DTV 방송 수신환경을 보다 정확하고 효율적으로 분석하기 위하여 DTV 수신 신호 및 채널 분석시스템의 기술적인 요구 사항을 제시하고, 이러한 요구 사항을 만족하게하고 좀 더 정확한 채널환경 분석을 위해 측정된 기저대역의 I 채널 데이터로부터 힐버트(Hilbert) 변환과정을 개선한 Q 채널 데이터 추출 방법을 제안한다. 제안된 데이터 및 채널 분석 시스템은 컴퓨터 모의실험과 실험실 테스트 결과를 통해서 성능을 입증하였으며, 방송신호 측정차량에 장착하여 DTV 동일채널중계기(DOCR) 필드테스트에서 다중경로간섭 신호의 분석에 적용하였다.

  • Visual media transmits image and information reproduced in large quantities, such as a photography, film, television, video, advertisement, or computer image. Correspondence to the students' reception and recognition of culture in the future. arrangements for the field of studies of visual culture. 'Visual Culture' implies cultural phenomena of visual images via visual media, which includes not only the categories of traditional arts like a painting, sculpture, print, or design, but the performance arts including a fashion show or parade of carnival, and the mass and electronic media like a photography, film, television, video, advertisement, cartoon, animation, or computer image. In the world of visual media, Image' functions as an essential medium of communication. Therefore, people call the culture of today fra of Image Culture', which has been converted from an alphabet convergence era to an image convergence one. Image, via visual media, has become a dominant means for communication in large part of human life, so we can designate an Image' as a typical aspect of visual culture today. Image, as an essential medium of communication, plays an important role in contemporary society. The one way is the conversion of analogue image like an actual picture, photograph, or film into digital one through the digitalization of digital camera or scanner as 'an analogue/digital commutator'. The other is a way of process with a computer drawing, or modeling of objects. It is appropriate to the production of pictorial and surreal images. Digital images, produced by the other, can be divided into the form of Pixel' and form of Vector'. Vector is a line linking the point of departure to the point of end, which organizes informations. Computer stores each line's standard location and correlative locations to one another Digital image shows for more 'Perfectness' than any other visual media. Digital image has been evolving in the diverse aspects, such as a production of geometrical or organic image compositing, interactive art, multimedia art, or web art, which has been applied a computer as an extended trot of painting. Someone often interprets digitalized copy with endless reproduction of original even as an extension of a print. Visual af is no longer a simple activity of representation by a painter or sculptor, but now is intimately associated with a matter of application of media. There is some problem in images via visual media. First, the image via media doesn't reflect a reality as it is, but reflects an artificial manipulated world, that is, a virtual reality. Second, the introduction of digital effect and the development of image processing technology have enhanced a spectacle of destructive and violent scenes. Third, a child intends to recognize the interactive images of computer game and virtual reality as a reality, or truth. Education needs not only to point out an ill effect of mass media and prevent the younger generation from being damaged by it, but also to offer a knowledge and know-how to cope actively with social, cultural circumstances. Visual media education is one of these essential methods for the contemporary and future human being in the overflowing of image informations. The fosterage of 'Visual Literacy' can be considered as a very purpose of visual media education. This is a way to lead an individual to the discerning, active consumer and producer of visual media in life as far as possible. The elements of 'Visual Literacy' can be divided into a faculty of recognition related to the visual media, a faculty of critical reception, a faculty of appropriate application, a faculty of active work and a faculty of creative modeling, which are promoted at the same time by the education of 'visual literacy'. In conclusion, the education of 'Visual Literacy' guides students to comprehend and discriminate the visual image media carefully, or receive them critically, apply them properly, or produce them creatively and voluntarily. Moreover, it leads to an artistic activity by means of new media. This education can be approached and enhanced by the connection and integration with real life. Visual arts and education of them play an important role in the digital era depended on visual communications via image information. Visual me야a of day functions as an essential element both in daily life and in arts. Students can soundly understand visual phenomena of today by means of visual media, and apply it as an expression tool of life culture as well. A new recognition and valuation visual image and media education is required to cultivate the capability of active, upright dealing with the changes of history of civilization. 1) Visual media education helps to cultivate a sensibility for images, which reacts to and deals with the circumstances. 2) It helps students to comprehend the contemporary arts and culture via new media. 3) It supplies a chance of students' experiencing a visual modeling by means of new media. 4) There are educational opportunities of images with temporality and spaciality, and therefore a discerning person becomes to increase. 5) The modeling activity via new media leads students to be continuously interested in the school and production of plastic arts. 6) It raises the ability of visual communications dealing with image information society. 7) An education of digital image is significant in respect of cultivation of man of talent for the future society of image information as well. To correspond to the changing and developing social, cultural circumstances, and the form and recognition of students' reception of them, visual arts education must arrange the field of studying on a new visual culture. Besides, a program needs to be developed, which is in more systematic and active level in relation to visual media education. Educational contents should be extended to the media for visual images, that is, photography, film, television, video, computer graphic, animation, music video, computer game and multimedia. Every media must be separately approached, because they maintain the modes and peculiarities of their own according to the conveyance form of message. The concrete and systematic method of teaching and the quality of education must be researched and developed, centering around the development of a course of study. Teacher's foundational capability of teaching should be cultivated for the visual media education. In this case, it must be paid attention to the fact that a technological level of media is considered as a secondary. Because school education doesn't intend to train expert and skillful producers, but intends to lay stress on the essential aesthetic one with visual media under the social and cultural context, in respect of a consumer including a man of culture.

  • This study is to examine the costumes of Gyeokgu in different situations and to suggest when and how they should be used in historical drama. Gyeokgu is a type of polo game that was played in Korea and it was also known as Gyeokbong and Bonghee. The accounts of the game show that it was played during the South-North period as recorded in Balhaego, Haedongyeoksa, and Goryeosa until the Joseon period. The scenes of Gyeokgu have been shown in some historical dramas in order to make the story exciting or to show the life of royalty. The costume of Gyeokgu in the South-North period should be suggested Danryeong(團領), Bokdu, and Haw(靴) in a formal situation. The Gyeokgu in the Goryeo period was a sport for royalty. So the Gyeokgu costume in the Goryeo period was required to be worn with Danryeong(團領), Bokdu, and Haw(靴) for the kings and military officers in the early Goryeo period and with Cheollik(帖裡), Balip or Huklip(黑笠), and Haw(靴) from the middle of the Goryeo period. Women could wear Chima(skirt), Jeogori(blouse), Pyo, and Li(履) when they play Gyeokgu in the Goryeo period in the historical dramas. The Gyeokgu in the early Joseon period was a sport for the kings. After the king of Sejong, the Gyeokgu became a martial art for the military officers. The costume of Gyeokgu in the Joseon period should be Red Cheollik(紅帖裡), Kwadu, Jonglip, Gwangjodae(廣組帶), Sagu, and Haw(靴) as recorded in Muyedobotongji in the 18th century. The kings, servants, and military officers could wear the Cheollik and should be made in the different Git(collar), shape of the sleeves, and the proportion of the upper part and the underpart in each period properly. When the citizens play Gyeokgu, they could wear Geon(巾), Baji(pants), Jeogori(shirt), and Gipsin in the late Joseon period.
