Since hand gesture recognition was realized thanks to improved image processing algorithms, sign language translation has been a critical issue for the hearing-impaired. In this paper, we extract human hand figures from a real time image stream and detect gestures in order to figure out which kind of hand language it means. We used depth-color calibrated image from the Kinect to extract human hands and made a decision tree in order to recognize the hand gesture. The decision tree contains information such as number of fingers, contours, and the hand's position inside a uniform sized image. We succeeded in recognizing 'Hangul', the Korean alphabet, with a recognizing rate of 98.16%. The average execution time per letter of the system was about 76.5msec, a reasonable speed considering hand language translation is based on almost still images. We expect that this research will help communication between the hearing-impaired and other people who don't know hand language.

본 논문은 복잡한 배경에서 표식없는 손을 추적하여 한글 수화를 인식하는 시스템에 관한 것이다. 제안한 방법은 먼저 인접한 프레임간의 차 영상에 대하여 엔트로피를 측정한다. 큰 값을 갖는 영역에 대해 피부색에 가까운 분포를 갖는 색상 정보를 추출하여 배경 영상으로부터 손 영역만을 추출한다. 추출된 손 영역에 대해 윤곽선을 검출하고 개선된 무게중심 프로필(centroidal profile) 방법을 적용하여 수화를 인식한다. 6가지 모양의 수화를 사용한 실험결과 기존의 방법들과 달리 표식을 사용하지 않고도 복잡한 배경과 조명의 변화에서 안정적으로 수화를 인식할 수 있다. 또한 초당 15프레임 정도의 처리속도로 각 사람별로 95%이상, 각 수화별로 $90\sim100%$의 인식률을 얻을 수 있다.

The use of colors plays an important role in the field of space design. The selection of proper colors influences on people who use space by making the most of the psychological and physical functions of colors. Especially, the medical space is relatively more important than other indoor spaces in the selection of colors. The medical space has to be something to do with diversity and functions, and at the same time with stability and quietude, as well as the space with general convenient facilities. Color is not only related to the expression but also to the distinction of things and the existence. It also functions as a visual language. Human beings depend heavily on the function of color as a visual language. According to previous studies, human beings depend on color by 80% of the whole range of eyesight. Thus, color is an important factor in recognizing things and space. For example, in hospital, it Is very important to apply proper colors to various medical treatment spaces for the sake of patients' rest and healing. Various colors which do not consider the function of patients' rest and healing may make the space confusing against the change of space and structure. It is also important to apply colors to the change of space and structure. Another key point that I would like to make is that color has visual, direct and physical influence on the human body. For example, the color red with long wavelength serves to regulate body temperature. Research on the color scheme for hospitals should consider both physical and psychological factors. That is why the research should be carried out in depth through continuous clinical demonstration. The present research aims to outline color planning.

Color can stir up the feeling and the thinking of the human inside, and heals human's illness. The color of architecture is a systematic physical space of shape and color. In other words, color is a kind of visual language organizing a structure and interact with human. The color of hospital can be specially effective to heal the elderly. This study intends to help geriatric hospital in future to elevate remedial value and indicate basic data for adapted the elderly environment. NCS is a kind of color system based on the human psychology and nature. This study researched the color of geriatric hospital with NCS and annualized the color nuance of each spaces. As a result the distribution of color nuance show the present of the geriatric hospital's color planning.

This paper proposes a new method for the recognition of resistor color band using a color segmentation in a HSI color model. The proposed method firstly segments a resistor in a chromatic color as a ROI from a background. Secondly, the color bands of the resistor are segmented by vertical projection profile using both the intensity and the saturation differentiation and finally, it recognizes the colors of the segmented color bands using hue, saturation and intensity values. The final results are the value of the resistor and the names of the recognized color. The proposed method is implemented using C language in Raspberry Pi system with a camera module for a real-time image processing. Experiments were conducted by using various resistor images. The results show that the proposed method is successful for the recognition of resistor color band.

This paper proposes a new color segmentation method of vehicle license plates in the RGB color space. Firstly, the proposed method shifts the histogram of an input image rightwards and then stretches the image of the histogram slide. Secondly, the method separates each of the three RGB color components and performs the adaptive threshold processing with the three components, respectively. Finally, it combines the three components under the condition of making up a segment color and removes noises with the morphological processing. The proposed method is implemented using C language in an embedded Linux system for a high-speed real-time image processing. Experiments were conducted by using real vehicle images. The results show that the proposed algorithm is successful for most vehicle images. However, the method fails in some vehicles when the body and the license plate have the same color.

중요한 시각적 요소로서 애니메이션영화의 색은 현실을 묘사할 수 있을 뿐만 아니라, 영화 공간을 형성하는 데 중요한 역할을 하는 감정과 의미를 전달할 수 있다. 가장 성공적인 애니메이션영화 중 하나로 <코코>는 영화 공간을 형성하기 위해 대담하고 독특한 색 언어를 사용한다. 민족 색상은 이야기 공간을 만들어 이야기 배경을 멕시코 지역 및 문화 풍습으로 가득 채우며, 색상 대조로 물리적 공간을 만들고 공간 모델링 및 차원 감을 뚜렷이 표현하며, 색상 연상 형식으로 심리적 공간을 만들어 관중들은 영화 정신세계에 인도하게 한다. <코코>의 공간 색상 분석을 통해, 애니메이션영화 공간 모델링은 색상의 특성 및 기능을 충분히 활용하고, 공간의 특성에 따라, 다른 색상 언어를 사용해야 하며 영화 공간의 표현 형식을 확장하고 영화 공간의 의미를 깊게 한다.

The meaning of the color which has from modern interior space has played important role, i.e. color itself Is the concept creation tool as well as the unique expression sphere in field of interior space far away from fixed idea relevant to the existing color which was only simple decoration or secondary element in space. Thus, this current work expresses that the color is related with decoration effect as well as basic designed-conceptual work process including the space is formed. Furthermore, through the side-composition with color, It activates the various space aspect perceptually, which created the colorful environment in using lightning, reflection of glass and penetrated nature etc. The keyword on color concept is as like various aspects, third dimension, non-materiality and symbolical meaning. In addition, it provides the color space equipped with functionality and artistry capable to arouse the diverse sensual capacity to space users on default of color image language.

This study aims to derive the sensitive image analysing the color tones based on the web-sites of cosmetic brand and to know how the web-site color tones and the color tone image as visual factor for information transfer do influence the effective communication. 10 cosmetic brand web-sites are selected based on the pre survey, and the main page color tones of cosmetic brand web-site are analyzed by Color Catch and Munsell Conversion program, whereas the composition of color tones and color image such as the main trend colors, secondary colors, accent colors and etc are analyzed by a graphic professional program 'Adobe Photoshop'. 5 color tone groups are classified as Black&White, Green&White, Blue&White, Purple&White and Red&White according to the color distribution chart, and the emotional language is derived applying them to the pre research and IRI image scale. The color association is empirically analyzed by a survey method. The study results finally show Black&White is proper for expression of high quality and modern image, Green&White for pure and clean image, Blue&White for cool and transparent image, Purple&White for mysterious and elegant image respectively. This study results are necessary for plan of color delivering the strong transferring power of visual information the time when to make the effective web-sites, and it hopefully will be utilized as the basic data for the color marketing to actively express the brand identity and to satisfy the consumers' sensitivity.
