For the autonomy of a mobile robot it is first needed to know its position and orientation. Various methods of estimating the position of a robot have been developed. However, it is still difficult to localize the robot without any initial position or orientation. In this paper we present the method how to make the colored map and how to calculate the position and direction of a robot using the angle data of an omnidirectional image. The wall of the map is rendered with the corresponding color images and the color histograms of images and the coordinates of feature points are stored in the map. Then a mobile robot gets the color omnidirectional image at arbitrary position and orientation, segments it and recognizes objects by multiple color indexing. Using the information of recognized objects robot can have enough feature points and localize itself.

For the students who specialize in interior design irrespective of their color susceptibility, it is prerequisite to precede a systematic curriculum in the first place on how to put the color theory to practical use. Therefore, this curriculum has its purpose to let the students study on how to put to practical use of their understanding of color as one of the finishing materials for interior design. The 16-weekschool days has been segmented into a theoretical study and practical training, This thesis has summed up the basic instance of the color theory, the first of the three basicpractical courses and presented its results to the students. In due course of this curriculum, the students were recommended to pick up one photo image of their selection out of which they could make out color palette based on their analysis of the photo image, so that they could study on how to apply their color palette to a three dimensional space. Firstly, through this course, they could experience the process for a color image that they had so far sensed subjectively and vaguely to become an objective inevitable result. Secondly, they studied on the process of how a two-dimensionalcolor image could be applied for a three-dimensional space. It is significant of this curriculum in the sense that the students become prepared through this study course with essential knowledge applicable to various interior designs in their future.

The purpose of this study is to help understanding of Korean fashion image by studying of design factor and formative characteristic. The methods of this study are the study of academic literatures as well as practical study through the analysis of case studies about actual works. The summary of this study's results is like followings. First, Perspectives seeing formative characteristic on Korean fashion image are Shape with a line, color, material, pattern, accessories. Second, Design factors deciding Korean fashion image are pattern, then in order of shape, color, material, accessories. Third, In results on design factor deciding Korean fashion image, when fashion designers focus on pattern, pattern is focused on without regard for other design factor. But color and material are accompanied by other design factor in expressing Korean fashion image. As fashion design point expressing Korean astetic, use of pattern is minimized other design factor, color and material are used with other design factor, then Korean fashion image will come out more than other time else. If We develop Korean fashion design to concentrate on shape and pattern, Korean fashion culture will be known to world people and beautiful value of Korean fashion will be handed effectively.

In this study, we introduce a new image gradient computation based on understanding of image generation. Most images consist of groups of pixels with similar color information because the images are generally obtained by taking a picture of the real world. The general gradient operator for an image compares only the neighboring pixels and cannot obtain information about a wide area, and there is a risk of falling into a local minimum problem. Therefore, it is necessary to attempt to introduce the gradient operator of the interval concept. We present a bow-tie gradient by color values of pixels on bow-tie region of a given pixel. To confirm the superiority of our study, we applied our bow-tie gradient to image segmentation algorithms for various images.

SDIAS (Single Doppler Image Analysis System), which can estimate the vertical wind profiles from single Doppler color displays, is developed here. Various single Doppler velocity signatures are simulated using horizontally uniform wind fields that vary with height. This system is very simple and efficient for interpreting the color displays. So, SDIAS can be used to get some useful informations on wind for understanding the present weather situation and forecast.

The high-rise and high-density apartment complexes are built on a large scale and occupy a large portion of the city. The facade of the apartment has a great influence on the cityscape. In particular, the lower part of apartment design gives people to important impressions. For the harmonious landscape of the city, the color plan emphasizes its importance as an influential visual design element that forms the urban landscape. In specialized apartment design, especially finishing material on lower-parts of apartment which is recognized by pedestrian is more important planning factor. Also, finishing material which is one of the primary design elements is important for making the entire image about the building with color. Nowadays stone is mostly used for specialized design on lower-level in apartments. Stone makes luxurious image and harmonious landscape as a nature material. But when planning for design, only general stone graphic or pictures is used without specific plan, after construction, there is a big difference between a plan and the actual color and image. Thus based on exact understanding of stone, I analyzed current state of expression for stone which is used for lower-parts of apartments in Daegu. By this, the purpose of this study is to present detailed data to offer the basis for planning specialized design of lower-parts of apartment.

오늘날 AI 이미지 생성 프로그램은 패션 상품 광고, 맞춤형 패션 스타일 제안, 디자인 개발 등 패션 산업 분야의 세분화된 목적에 알맞게 개발되고 있다. 한편 색상은 강력한 조형 요소로서 상품이나 패션 스타일 제안을 위한 이미지 표현에 중요한 역할을 한다. 본 연구는 AI 이미지 생성 도구 중에서 미드저니를 사용하여 생성한 의상 이미지에 나타나는 색상과 배색 관계에 중점을 두어 그 특징을 파악함으로써 미드저니의 활용에 대한 이해를 넓히고자 한다. 본 연구의 결과는 다음과 같다. 첫째, 미드저니에서 생성한 초기의 이미지는 명령어에 지시한 색상보다 이미지 생성을 위하여 사용한 기존의 이미지 색상에 더 의존적으로 반영되어 나타난다. 둘째, 미드저니에서 생성된 이미지의 의상에 나타난 배색의 특징은 의상의 구조에 따라 구분되는 부위별로 다른 색상이 표현된 분리배색과 의상의 한 부위에 다른 색상들이 무늬 형태로 표현된 혼합배색이 생성된다. 분리배색에 표현된 색상들의 비율은 명령어에 지시한 색상 순서의 영향을 받는다. 혼합배색에 조합되어 나타난 색상 수는 미드저니에서 이미지 생성을 위하여 사용한 기존의 이미지 속 의상의 색상 수와 명령어에 지시한 색상 수의 총합보다 적은 수의 색상으로 조합되어 나타난다. 셋째, 미드저니는 생성하는 이미지의 배경도 색상 표현을 위한 대상으로 인식하며 이에 따른 배경색의 변화는 이미지 속의 의상에 대한 사용자의 색지각과 의상 이미지 형성에 영향을 미칠 수 있으므로 주의가 필요하다. 본 연구 결과가 패션디자인 교육과 실무에 있어 미드저니에서 생성되는 이미지의 색상 배색에 대한 이해를 넓히고 이를 통하여 미드저니의 활용에 도움이 되기를 기대한다.

Optical Color Corescanner firstly developed by DMT-GeoTec, Germany and further upgraded through the Korea-Germany joint project is capable of duplicating the core surfaces. The tool uses a digital CCD line camera. As the core is rotated by an electric motor, the camera scans the uppermost line, everytime with a circumferential increment of up to 0.05mm(20pixels/mm) and hence a complete 360$^{\circ}$ unwrapped image(core image) is produced. This paper illustrated diverse research benefits of such core images from several test sites in our country. All scanned images could be stored as a data-base one and easily used with software facilities \circled1 to evaluate a percental distribution of mineral components or grain size etc. not only for the rock classification but also for e.g. the assessment of building stones, \circled2 to study potential reservoirs as a hydrocarbon indicator using ultraviolet fluorescence reflection from cores, \circled3 to facilitate the qualitative and quantitative analysis of fractures, \circled4 to evaluate the fractures and thin bedded reservoirs using spectral color responses. Based on abundant scanning experiments, it would seem that this imaging work should lead to reflecting the future trend in underground survey toward a more comprehensive understanding of the properties and behaviors of in situ rocks.
