Odometry is the critical factor to estimate the location of the robot. In the mobile robot with wheels, odometry can be performed using the information from the encoder. However, the information of location in the encoder is inaccurate because of the errors caused by the wheel's alignment or slip. In general, visual odometer has been used to compensate for the kinetic errors of robot. In case of using the visual odometry under some robot system, the kinetic analysis is required for compensation of errors, which means that the conventional visual odometry cannot be easily applied to the implementation of the other type of the robot system. In this paper, the novel visual odometry, which employs only the single camera toward the ground, is proposed. The camera is mounted at the center of the bottom of the mobile robot. Feature points of the ground image are extracted by using median filter and color contrast filter. In addition, the linear and angular vectors of the mobile robot are calculated with feature points matching, and the visual odometry is performed by using these linear and angular vectors. The proposed odometry is verified through the experimental results of driving tests using the encoder and the new visual odometry.

This study was initiated for the purpose of improving the visual effect of lingerie design, and it focused on the image factors and their characteristics of the lingerie design. Images of 105 lingerie design were evaluated by 3-5 images/participant with each image being evaluated 15 times through the SD method 5-scale questionnaire. The lingerie design elements were also analyzed by a committee. For data analysis, SPSS 10.0 program was used, and the principal component analysis, Ward-cluster, K-mean cluster analysis, ANOVA, duncan-test were conducted. The results are as follows: 1) The three major characteristics of the visual images in the lingerie design were aesthetics, dignity, and youth, which were supported 76.78% by the responses. 2) The visual image types can be categorized into four clusters; a dignified style, a sprightly style, a practical style, and a sexual style. 3) The design elements that allowed different design characteristics among the image types were style(one-piece/two-piece), total length, waist fit, matching color, silky lustrous, see-through on waist, hip, race percentages. 4) The ABC(apparel-body-construct) observed that a practical style was perceived as flat and whole rather than a dignified style or a sprightly style, while a sexual style was seen as round and partial.

Since 1988 the fur fashion industry in Korea has been difficult in exporting and competition with too many brands after opening the dom-estic fur market. However comparing with the interest of manufactures and consumers there are few of related references and books. So the purpose of this study is to put in order and summurize the manufacture in fur cloth-ing the informations of domestic and oversea fur markets and the other professional references. After all it is to help succeed in domestic and international fur markets and give the new ideas of designing and merchandising to the fur fashion industry. The results were as follows: 1. Contact with fur specialty stores in the international fashion cities and tourist cities directly. 2. Establish oversea factories in the low labor countries. 3. Exploit and invest in Russia china and the East European countries for suppliment of law materials and fur market. 4. Need the market research and promotion for encroachment in Japanese fur market. 5. Create the original brands with inter-national fashion sense. 6. Develop the manufacture line for diverse models in small lots matching with the modern life styles. 7. Need the fashion show exhibition pro-motion with reasonable prices and creative new designing with various color trimming texturizing and combination with the other materials. 8 Subdivide and distinguish labels into different types for avoiding with too much com-petition and comvenience of consumers. 9. Make an effort to weaken the black mar-ket the 30% of the domestic fur market.

This study examined characteristics and structure of earthen Janggu that were excavated from Jeollabuk-do and other regions, and it described conservation process of earthen Janggu that were excavated from Samsanyujeok Jeonju. Earthen Janggu that were excavated from Samsanyujeok were destroyed and lost by more than one third, and they were thought to make use of them at living lives. We take an x-ray of center of the Janggu for inspect production technique and, destroyed area of the Janggu was recovered by making recovery frame made by plaster and using epoxy series CDK-520. After recovery, acrylic paint was used to do color matching and to get rid of sense of difference of the area that was recovered and remained.

본 논문에서는 새로운 HAC(Histogram Area Calculation)방법과 영상의 객체분할 방법을 소개한다. 히스토그램을 이용한 영상은 색상 공간의 특징 때문에 조명에 매우 민감하여 빛의 강도에 따라 유사성이 저하되는 경우가 있다. 또한 공간적 정보를 가지고 있지 않아, 전혀 다른 모양의 영상일지라도 칼라 분포가 같은 영상으로 볼 수 있다. 이 논문에서 제안한 방법은 히스토그램 영역을 임의의 영역으로 나눠, 영역들의 유사성을 매칭(matching) 시킨다. 2차 검색방법으로 원 영상에서의 색상 질감 정보가 동일한 영역을 군집화 하여, 영상 분할된 객체들을 이용하여 검색하는 방법이다. 실험 결과, 제안한 방법이 전통적인 히스토그램 방법보다 검색 성능이 효율적인 결과를 얻었다.

As the smart media becomes more popular, the demand for high-quality 3D images and depth maps is increasing. However, performance of the current technologies to acquire depth maps is not sufficient. The depth maps from stereo matching methods have low accuracy in homogeneous regions. The depth maps from depth cameras are noisy and have low-resolution due to technical limitations. In this paper, we introduce the state-of-the-art algorithms for depth map enhancement and up-sampling from conventional methods using only depth maps to the latest algorithms referring to both depth maps and their corresponding color images. We also present depth map enhancement algorithms for hybrid camera systems in detail.

Treatment of PET fabrics with alkali, chitosan and Al-mordanting has been carried out and the role of the chitosan coating in the dyeing process was clarified. The pre-treatment was effectively evaluated differences in dyeing behavior between its treated and untreated PET fabrics using wood of Caesalpinia sappan. The pre-treated on PET fabrics has been examined by SEM and evidence for the presence of chitosan sought using a air permeability test. Similar colour fastness by computer color matching(CCM) obtained on both untreated and pre-treated PET fabrics. The pre-treated PET was found to be of a deeper hue to that of its dyed untreated PET and, despite of its better colour depth, the wash fastness of the pre-treated dyeing was comparable to that of its dyed untreated PR. The application of chitosan or mordanting reveled that pre-treatment imparted to the PET additional functional groups that were available for coordination with the Brazilin.

Our government has declared the "Synthetic Project for Promoting Han-style" to industrialize and globalize the original form of Korea traditional culture. Han-bok, our traditional folk costume is one of the main subject of this project. However it is the global trend not to wear their traditional folk costume. And so, the number of people wearing Han-bok, our traditional folk costume is also getting gradually decreased in Korea. For Han-style Promoting Project in the future, it is one of the most efficient way for the middle and high school students to motivate and increase the interest about Han-style and Han-bok as the middle and high school uniforms. Adolescent middle and high school students think very important their appearance. Especially, Korean middle and high school students spend a lot of time in school, and so school uniforms are very influential in their mental and physical aspects. Fabrics for this study, they were woven twill with 3 kinds of fabric patterns from the motif of Baekje relics. The colors of fabrics is the blue and brown used in general school uniform, the yellow and red used in Han-bok. Considering the school uniforms, fabric patterns adapted the similar color matching method for not to be found cleary and designed the fabric pattern's one-repeat size is $4{\times}4cm$.

This paper is concerned with an efficient generation of stereoscopic views for complex virtual environments by exploiting frame coherence in visibility. The basic idea is to keep visible polygons throughout the rendering process. P-buffer, a buffer of image size, holds the id of the visible polygon for each pixel. This contrasts to the frame buffer and the Z-buffer which hold the color information and the depth information, respectively. For the generation of a consecutive image, the position and the orientation of the visible polygons in the current view are updated according to the viewer's movements, and re-rendered on the current image under the assumption that, when the viewer moves slightly, the visibility of polygons remains unchanged. In the case of stereoscopic views, it may not introduce much difficulty when we render the right(left) image using visible polygons on the (right) image only, The less difference in two images is, the easier the matching becomes in perceiving depth. Some psychophysical experiments have been conducted to support this claim. The computational complexity for generating a fight(left) image from the previous left(right) image is bounded by the size of image space, and accordingly. It is somewhat independent of the complexity of the 3-D scene.
