In this paper, We propose a method with which we can detect facial components and face in input image. We use eye map and mouth map to detect facial components using eyes and mouth. First, We find out eye zone, and second, We find out color value distribution of skin region using the color around the eye zone. Skin region have characteristic distribution in YCbCr color space. By using it, we separate the skin region and background area. We find out the color value distribution of the extracted skin region and extract around the region. Then, detect mouth using mouthmap from extracted skin region. Proposed method is better than traditional method the reason for it comes good result with accurate mouth region.

본 논문에서는 3차원 입체 비디오처리 기술의 최종목표인 디지털 홀로그램을 생성하는데 필요한 객체의 좌표와 색상정보가 들어있는 같은 시점과 해상도인 RGB 영상과 깊이 영상을 획득하여 가상 시점의 디지털 홀로그램을 생성하는 시스템을 제안한다. 먼저, 가시광선과 적외선의 파장을 이용하여 파장에 따라 투과율이 달라지는 콜드 미러를 사용하여 각각의 시점이 같은 다시점 RGB와 깊이 영상을 얻는다. 카메라 시스템이 갖는 다양한 렌즈 왜곡을 없애기 위한 보정 과정을 거친 후에 해상도가 서로 틀린 RGB 영상과 깊이 영상의 해상도를 같게 조절한다. 그 다음, DIBR(Depth Image Based Rendering) 알고리즘을 이용하여 원하는 가상 시점의 깊이 정보와 RGB 영상을 생성한다. 그리고 깊이 정보를 이용하여 디지털 홀로그램으로 구현할 객체만을 추출한다. 마지막으로 컴퓨터 생성 홀로그램 (computer-generated hologram, CGH) 알고리즘을 이용하여 추출한 가상 시점의 객체를 디지털 홀로그램으로 변환한다.

모든 공산품에서 색은 사용자의 감성적 인터페이스에 매우 중요한 요소로 고려되고 있다 특히 컴퓨터 모니터와 같은 컬러 디스플레이의 경우 색상의 표현특성이 사용자의 감성적 만족도에 영향을 주는 중요한 요인이라고 할 수 있다. 최근에는 멀티미디어의 대중화로 대부분의 사람들이 컬러 디스플레이를 사용하여 광범위한 영역의 영상정보를 주고받게 되므로 정확한 색의 재현은 정보의 전달에 중요한 요인이 되고 있다. (중략)

과학과 기술, 통신의 급속한 발달은 새로운 매체의 예술을 가능하게 한다. 컴퓨터의 마우스를 움직여서 색상을 선정하고 원하는 선이나 형태를 선택하며 편집하고 조합하여 미술계에도 디지털미디어가 새로운 표현수단으로 이용되고 있다. 이렇듯 컴퓨터와 인터넷을 통한 예술은 새로운 세기의 문화의 상징으로 전세계를 네트워크로 구성하는 또다른 예술형태를 창조해 내고 있다.

In today's modern society, since the Industrial Revolution took place, still lots of goods have been produced in quantity. However, human's instinct has been growing bigger and bigger that he or she wants to possess the works or products of scarcity and aesthetic value of a sculpture handmade by craftsmen, not mass-produced with the same design patterns. Accordingly, it is required that an artist be concerned about the value of figuring out and pursuing an individual's lifestyle, his/her needs and inherent desires. Moreover, by means of visualization technique, an artist should provide the public with several scenarios about the future, letting them choose the one they want democratically. Therefore, with the help of Mokumegane technique, one of the traditional metal crafts techniques, which shows certain organic patterns joining different metals, this research aims for the inheritance of traditional techniques and the objective preparation for high-quality crafts market, studying the patterns expressed on the surface of metals, which are hard to find through machines.

Displays, playing an essential role in HCI, have been developed to deliver more vivid and live pictures. LCD and PDP have the most common usage among various displays to present the dynamic textual information in restricted and open places. Important and unsolicited information is being provided by hundreds of displays while we don't even perceive the information. Watching context, effective color combinations of the text and background, speeds of presentation, contexts, and types of display for leading method, moving words cross the display from right to left, were investigated with readability, comprehensibility, and overall satisfaction were compared. LCD peformed better than PDP on all comparisons u4th typical text (black, white) and background (white, black) color better than other color combinations. Normal and fast text presentation was believed more preferred when only textual information was given while slower presentation was evaluated more efficient if multimedia contents were presented with textual information.

Recently, many interactive artworks produce through convergence of art and scientific technology. Artists or designers should cooperate with other areas for analysis in order to share database. According to these requirements, In this study, we analyze Kandinsky's works which are more emphasis on subject area than the emphasis to background area by using a number of colors, faces, and brightness levels. Due to this approach, it determines how to represent for stable screen composition attracting viewer's eyes. As a result, the subject area has more a number of colors, faces, and brightness levels than the background area. In addition, we produce the interactive artwork based on the analyzed data. According to the requirement of convergence and collaboration in the historical background, this study will be able to contribute to make the collaboration by sharing common information between artists and professionals in other areas. In addition, it is expected that other production makers who do not have the background of arts education will be able to configure the visual screen.

Scanimation is utilized in various fields due to its simple and easy basic principle, whereas mostly it is expressed in gray scale, and the cases of expressing with color is rare. This research classified scanimation into form change of the images with no connectivity, continuous motion of the images with connectivity, and optical illusion with continuity along with visualization effect based on the advanced research and utilization case, and conducted a comparative analysis of scanimation per type applied with color scheme by color difference based on PCCS(Practical Color Co-ordinate System) system. Based on this research, the researcher intended to suggest various direction and expressive method of scanimation using color, expecting the research result could be a valuable reference for the researches utilizing scanimation, henceforth.

This study is an attempt to analyze the changes and morphological analysis of the one length hair style of women in the Imperial Japanese colonial period, and the purpose of this study is to analyze the components of hair design such as shape, texture, and color based on the precedent and the book and to make possible various styles of one length hair style cut. From the results of this study, one length hair style showed the outline shape with no step height of cut length, natural hair texture and natural hair color in 1910s to 1920s. In the 1930s, the one length hair style showed a slight cut length step height and a slight discoloration using a diamond shape, a narrow wave of natural texture, hydrogen peroxide or oxygenated water. In the 1940s, one length hair style did not find any singularity to pursue brilliant beauty(美) in terms of form, texture, and color. This study may enable a deep and detailed follow up study on one length hair style, and will be a cornerstone for the development of basic data of hair beauty education and trend of new mode.

The detection of foreground objects in a projection display using color information can be hard due to changing lighting conditions and complex backgrounds. Accordingly, the current paper proposes a foreground object detection method using color information that is obtained from the input image to the Projector and an image captured by a camera above the projection display. After pixel correspondences between the two images are found by calibrating the geometry distortion and color distortion, the natural color variations are estimated for the projection display. Then, any pixel that has another variation not resulting from natural geometry or color distortion is considered a part of foreground objects, because a foreground object in a projection display changes the values of pixels. As shown by experimental results, the proposed foreground detection method is applicable to an interactive projection display system such as the DigitalDesk
