  • In this paper, we propose a new color interpolation method based on trilateral filter approach, which not only preserve the high-frequency components(image edge) while interpolating the missing raw data of color image(bayer data pattern), but also immune to the image noise components and better preserve the detail of the low-frequency components. The method is the trilateral filter approach applying a gradient to the low frequency components of the image signal in order to preserve the high-frequency components and the detail of the low-frequency components through the measure of the freedom of similarity among adjacent pixels. And also we perform Gaussian smoothing to the interpolated image data in order to robust to the noise. In this paper, we compare the conventional demosaicing algorithm and the proposed algorithm using 10 test images in terms of hue MAD, saturation MAD and CPSNR for the objective evaluation, and verify the performance of the proposed algorithm.

  • In this paper, the Artificial Intelligence Space(AI-Space) for human-robot interface is presented, which can enable human-computer interfacing, networked camera conferencing, industrial monitoring, service and training applications. We present a method for representing, tracking, and objects(human, robot, chair) following by fusing distributed multiple vision systems in AI-Space. The article presents the integration of color distributions into particle filtering. Particle filters provide a robust tracking framework under ambiguous conditions. We propose to track the moving objects(human, robot, chair) by generating hypotheses not in the image plane but on the top-view reconstruction of the scene.

  • The purpose of this study is to link traditional patterns to man's fashion goods design. Of all the traditional patterns, the bat pattern was chosen for use during the development of a man's fashion goods design as like as neck-tie, pocketchief and scarf. This study is based upon document searches, including research papers. Thought these searches, it investigates the form of traditional bat patterns, tessellation which can be found easily in the Islamic culture as well as in tile and carpet patterns and a modern painting by Gustav Klimt(1862-1918). Based on this investigation, the study attempt to modernize the bat pattern and apply the neck-tie, pocketchief and scarf. The design procedure includes three sub-processes: selection, arrangement and color-scheme. In conclusion, six designs of man's fashion goods were created by using one of Korea's traditional patterns - the bat pattern. Therefore, this study offer invaluable suggestions for multifaced research on how to come up with design concepts which apply Korea's traditional patterns to Man's fashion goods design.

  • The purpose of this study is to analyze check pattern of nail art from 2011 to 2013. The results of this study are as follows; 1) Check pattern of nail art is total 257 patterns, and there are 84 argyle, 29 tartan, 24 harlequin, 24 over, 23 window-pane, 15 stitcheds, 13 hound tooth, 10 block, 10 madras, 8 gingham, 8 gradation, 7 shepherd, and 2 tattersall check patterns. Through this result, in nail art, the relatively simple patterns such as a vertical pattern, a horizontal pattern, and cross or overlap diagonal line are used more than elaborate and complex check patterns of a fibrous tissue from a weaving process. 2) In check pattern of nail art, N-affiliated color and R-affiliated color are remarkably well-used, because of the effects of argyle, tartan, window-pane, harlequin, stitched, over, and hound tooth check patterns used the most during the past three years. Especially, most tartan, harlequin, over, and hound tooth check patterns use their own special colors such as R-affiliated colors and N-affiliated colors as it is, and argyle, window-pane, stitched, and over check patterns use well by arranging N-affiliated colors and R-affiliated colors. 3) The most used expressive technique is hand painting to express check pattern in nail art, because new products related to UV gel are well launched. These materials can draw fine line that is hard to express by existing polish easily and simply, and not only have set quickly hard, so procedure time is very short, so it is compatible to draw check pattern personally, but also it is well covered, so check pattern is more clearly expressed.

  • The purpose of this study is to develop eco-printing method using natural dyes combined with chitosan treatment to impart various pattern effect on cotton fabric. It was examined whether tone-on-tone pattern effects could be produced by screen printing with chitosan paste and subsequently dip-dyed in natural dye bath. For polychromic colorants, fabrics were pre-mordanted and then screen printed with chitosan, while only chitosan printing treatment was applied for monochromic colorants. Color, dye uptake, washing, light and rubbing fastnesses of printed fabrics were measured in relation to the presence of chitosan printing. Pre-mordanting and chitosan printing treatment were applied to such polychromic colorants as madder, sappanwood, onion and cochineal. Also, printing pattern formation on fabrics was evaluated by differences in dye uptake and color. The results suggested that madder, onion and cochineal were effective on pattern formation. Regarding sappanwood, since dye uptake was increased only by pre-mordanting without chitosan printing treatment, there was little color difference and thus patterns were not clearly distinguished. Chitosan printing treatment tended to increase washing, light and rubbing fastnesses of dyed fabrics with polychromic colorants. Chitosan printing treatment was applied to monochromic colorants such as chlorophyll, gardenia and indigo and the effect of printing formation was examined according to the difference in dye uptake. Among monochromic dyes tried, chlorophyll was effective and chitosan printing improved washing and light fastnesses.

  • This study was carried out to investigate the fatty acid composition, aroma pattern, color, and oxidative stability of M. longissimus from 28-mon-old Hanwoo steers with different raising altitude (100, 200, 300, 400, 700, and 800 m above sea level). The samples were stored at $2{\pm}0.2^{\circ}C$ for 9 d. Meat from 700 and 800m had lower palmitic acid, saturated fatty acids and higher oleic acid, monounsaturated fatty acids (MUFA) than that from 100 m (p<0.05). There was no positive discrimination of the aroma pattern of meat among all groups. There were no significant difference in TBARS values of beef among all groups at 6 and 9 d of storage. At 9d of storage, meat from 700m showed the highest MetMb concentration and the lowest a* value among all groups. However, the differences in Mb concentration and color among groups were not linear to the difference in raising altitude. Consequently, the difference in raising altitude at 100-800 m affected the fatty acid composition of meat from Hanwoo steers; the higher the raising altitude, the higher the MUFA concentration. The difference in fatty acid composition among them didn't affect the aroma pattern and oxidative stability.

  • 파밤나방(Spodoptera exigua (H bner)) 유충의 형태적 유전지표를 규명하기 위해 유충의 체색과 줄무늬 변이에 관하여 분석하였다. 유충 체색은 먹이 종류에 따라 다양했다. 유충 줄무늬는 배선과 측선의 존재에 따라 3종류의 형질 개체로 나뉘었다. 3줄무늬(배선과 측선 모두존재), 1줄무늬(배선만존재), 0줄(배선과 측선 모두 없음). 이들 형질이 유전적 영향에 있는지를 조사하기 위해 3줄과 1줄집단으로 집단선발한 결과 각 선발 형질의 비율이 증가했다. 3줄과 1줄집단을 상호교배하였을 때 3줄 형질이 우성을 보였다. 줄무늬 형질에 있어서 협의의 유전력(h$^2$)은 $0.50\pm$0.42로 산출되었다. 0줄집단에서 암컷수가 수컷수에 비해 약2배 많았다. 환경적 요인을 조사하기 위해 동일 집단을 3종류의 먹이에서 사육했을때 인공사료와 상치로 키운 집단간에는 유충줄무늬에는 유의성있는 차이는 없지만 파로 사육된 집단에서는 3줄개체의 비율이 낮아져 차이를 보였다. 이들 유충의 줄무늬는 유충과 용의 발육속도 및 내한성과 연관성을 보였으나 살충제 감수성과는 무관함을 나타냈다.

  • The purpose of this research to look into formative characteristics of eco T-shirt design. Previous study researchers have mostly focused on overall eco fashion design, but on the other hand the research on eco product entity leaves much to be desired. We analyzed formative characteristics of eco T-shirt design that is easily accessible in real life and is easy to passing message. We selected 23 eco brands through internet and analyzed total 500 photos of eco T-shirt. Each photo was categorized by sex and the nations which belong to the eco fashion world associations. The content and statistical analysis was used for data analysis. The content of the research is as the following. First, it was found out that basic straight silhouette, achromatic color, human pattern, plant pattern, and eco-friendly organic material were used for the design of eco T-shirt. Second, it showed difference of silhouette, color, pattern according to nations. Third, it showed difference of silhouette, color, pattern according to sex. Fourth, symbolism of eco T-shirt was nature love, nature support, society ethicality, anti-sociality, and economics. This research aims for providing practical help and assistance to the development of eco T-shirt and its relevant industries.

  • This paper proposes a novel active stereo matching technique using white auxiliary stripe pattern. The conventional active stereo matching techniques that uses two cameras and an active source such as projector can accurately estimate disparity information even in the areas with low texture compared to the passive ones. However, it is difficult that the conventional active stereo matching techniques using color code patterns acquire these patterns robustly if the object is composed of various colors or is exposed to complex lighting condition. To overcome this problem, the proposed method uses an additional white auxiliary stripe pattern to get and localize the color code patterns robustly. This paper proposes a process based on adaptive thresholding and thinning to obtain the auxiliary pattern accurately. Experimental results show that the proposed method more precisely measures the stepped sample whose depth is known in advance than the conventional method.
