The purpose of this study was to prepare the visual communication tool, which would be used for the interior design consulation to reduce the communication gap between an interior designer and a client. To achieve the study purpose, review of literature, questionnaire survey, qualitative analysis and design research methods were used. The major results of this study were as follows: 1) "Image Cube" was designed as a comprehensive rule to classify interior image types. By this, eight interior image types were classified: SFU(Simple-Formal-Urbane), SFN(Simple-Formal-Natural), SCU(Simple-Casual-Urbane), SCN(Simple-Casual-Natural), DFU(Decorative-Formal-Urbane), DFN(Decorative-Formal-Natural), DCU(Decorative-Casual-Urbane), DCN(Decorative-Casual-Natural). 2) The Interior image collages were composed to present the overall feeling of each interior image type. 3) The Interior image models which would be used as the standard to be modified to various sub-types through the interior design consultation were produced corresponding to interior image types.age types.

This paper proposes an indoor location positioning system for the image recognition based LBS. The proposed system is a vision-based location positioning system that is implemented the augmented reality by overlaying the location results with the view of the user. For implementing, the proposed system uses the pattern matching and location model to recognize user location from images taken by a wearable mobile PC with camera. In the proposed system, the system uses the pattern matching and location model for recognizing a personal location in image sequences. The system is estimated user location by the image sequence matching and marker detection methods, and is recognized user location by using the pre-defined location model. To detect marker in image sequences, the proposed system apply to the adaptive thresholding method, and by using the location model to recognize a location, the system can be obtained more accurate and efficient results. Experimental results show that the proposed system has both quality and performance to be used as an indoor location-based services(LBS) for visitors in various environments.

본 논문은 실내가구 인테리어를 배치하는데 있어 증강현실 기술을 적용하여 작업의 효율성을 높일 수 있는 모델을 연구하였다. 현재 증강현실을 적용하는 프로세스에서는 가구의 이미지를 출력할 때 기업의 규모나 제품의 성격 등에 따라 정보가 제한적으로 제공되는 문제를 안고 있다. 이러한 문제점을 해결하기 위하여 본 논문에서 제시하는 알고리즘을 이용하여 AR 레이블링을 생성함으로써, 가구의 정확한 이미지 추출과 함께 가구에 대한 상세한 정보를 제공 받아 사용자가 원하는 가구들을 증강현실을 통해 쉽게 배치할 수 있도록 하는 연구를 진행하였다. 본 연구는 AR 레이블링의 설계, 구현과 3D 렌더링을 통해 원하는 가구들을 실내에 정확히 배치할 수 있어 소비자의 만족도와 구매욕구를 충족시킬 수 있을 것으로 기대된다.

The purpose of this study was to investigate the female college students' preferences to the images of both western and eastern pictures, and positive/negative perception on to the model's nationality in the apparel advertizing pictures of fashion magazines. 100 students participated in the survey, and 20 stimulus pictures were shown to them. The results were as follows: The female college students preferred the western images than the eastern images in the pictures of bedroom, palace and beer, while they preferred the eastern images in the pictures of snack and famous drawings of a beauty. But they showed more positive attitude to all the western models' advertizement pictures than the eastern models' ones, in casual wear, formal wear, watches and inner-wear divisions except in men's formal wear division. This meant that the perception of female students on western images was positive and it seems stimulating the consumers preferences of brand images.

The CMYK is the mathematical color model and the Musell system is an intuitive color model. CMYK color model needs to be proposed in the information age. These two models need to be integrated for convenience of color design. This paper deals with CMRK values, which have appeared in interior design, in association with the Munsell code. Firstly, color samples have been extracted from the cases of interior design. Secondly, the CMRK values of the color sample and the Munsell code have been found. Thirdly, relationship between the CMRK values has been formularized in comparison with the Whelan's color pallette by using the regression method. This paper concludes by proposing the formular which can be used to develope color palette in further research.

실내 환경에서 사람의 행동을 인식하는 시스템을 만들 때 사람의 의도를 파악하는 것은 중요한 정보가 될 수 있다. 사람의 시선방향은 의도를 파악하는데 있어서 깊은 관계가 있다. 본 논문에서는 실내 환경에서 사람의 시선 방향을 모델에 기반하여 추정하는 방법을 제안하였다. 머리 모델은 얼굴 영역과 머리카락 영역을 포함하는 두 개의 겹쳐진 타원으로 표현되고, 각 타원의 파라미터는 시선 방향을 추정하는 정보로 사용된다. 시선 방향은 SVM(Support Vector Machine) 알고리즘을 사용하여 8방향중 하나로 추정된다. 이미지에서 얼굴영역과 머리영역은 색상 정보에 의해 검출된다. 사무실 환경에서 시선방향을 다양하게 변화시켜 실험을 하였고, 이를 통해 성능 평가를 수행하였다.

Users' demands on the space are changing in variety. These demands include reasonable space and form, harmonious composition with surroundings and esthetic satisfaction that could be brought by personal tastes and preferences. In addition, models that are introduced from designing process and from various forms tend to lack objective decision making standard. Accordingly it is difficult to find a clear alternative plan and process. In an effort to solve these problems, the objects of this study are; to propose an analysis model of image and space by using image process techniques that are on study in the field of artificial intelligence based on acquisition of digital image and to verify the application possibilities of such analysis model, 'Isovist' on quantitative analysis. The model can be applied with variable analysis model, as digital image process and other analysis model such as 'Isovist' It is possible that further study can complement problems from this study.

This paper investigates applicability of Microsoft $Kinect^{(R)}$, RGB-depth camera, to implement a 3D image and spatial information for sensing a target. The relationship between the image of the Kinect camera and the pixel coordinate system is formulated. The calibration of the camera provides the depth and RGB information of the target. The intrinsic parameters are calculated through a checker board experiment and focal length, principal point, and distortion coefficient are obtained. The extrinsic parameters regarding the relationship between the two Kinect cameras consist of rotational matrix and translational vector. The spatial images of 2D projection space are converted to a 3D images, resulting on spatial information on the basis of the depth and RGB information. The measurement is verified through comparison with the length and location of the 2D images of the target structure.

The purpose of this study is to suggest the prediction model for the color design by the image types in the office interior. This prediction model of the color design is for the more comfortable environment by using suitable, various colors fitted with business functions. In this research, we carried out the evaluation experiment with the variables such as the color on ceiling, wall, floor and the harmonies of color schemes. We set the prediction index through the multi-regression analysis. And the prediction model was made by these results. The design methods by the prediction model are as follows. 1) The $\ulcorner$variable$\lrcorner$ image was deeply influenced by the value and chroma and it was marked high in low value and high chroma and the harmonies of contrast and different color. 2) The $\ulcorner$comfortable$\lrcorner$ image was related to the value and chroma and it was marked high in high value and low chroma and harmonies of homogeneity and similar. 3) The $\ulcorner$warm$\lrcorner$ image was greatly influenced by the hue and the harmony of color schemes, and it was marked high in the warm colors and harmonies of homogeneity.
