Fiber industry is export leading industry that guide national economy development after the 1960s in Korea. But lately, including China and Southeast Asia pursuit, domestic fiber industry is taking serious situation. Various kind methods can be proposed for high value added in fiber industry, the research about color is essential. The importance of color is increasing in modern textile and fashion industry. Color is important factor of textile and fashion industry because color affects strong influence in human's sensitivity. Color expresses by hue, value and chroma but fashion industry is using mainly hue and tone color system. Daegu Gyeongbuk area is domestic maximum syntheic fiber producing district. This study planned the polyester standard color collections for general color management of the polyester industry in Daegu Gyeongbuk. As basic research for this I investigated the color appearance distribution of polyester fabrics in Daegu Gyeongbuk that were produced for the recently 10 years and Japanese polyester color collections "SCOTDIC 2450". Reflect these study finding, in this research planned the usable standard color collections "Hue and Tone Polyester Standard Color 288". This research constructs insufficient domestic color infrastructure and expect that basic role to develop the competitive power for Korean fiber industry.

Lighting energy accounts for approximately 20% of the electrical energy used worldwide. Thus, High efficiency Light emitting diode(LED)lighting is getting more popular as the next generation lighting replaced to traditional lighting fixtures. Also, LED lighting not only has a long lifetime but also can realize a variety visual environments through the wavelengh control. The lighting energy varies depending on the Spectral Power Distribution(SPD) even though the Illuminance level is same. Therefore, This study indicates that the difference of indoor energy consumption under the same illuminance level when Spectral Power Distribution(SPD) is different. As a result, Lighting energy consumption under red-color emphasizing SPD is about 10% lower than under blue-color emphasizing SPDs.

In this paper, we propose an robust CAMShift method to track stage objects with a camera. In order to solve the problem of tracking object misdetection in existing CAMShift technique, MBR region is detected to separate the background and the subject, and the subject size of the region of interest is calculated to solve the problem of erroneously detecting a large region having a similar color distribution ratio. Also, by applying the color corelogram and MB-LBP to the part that can not be solved by the color ratio and the size limitation, accurate texture tracking is enabled by reflecting the texture characteristics. Experimental results show that the proposed method has good tracking performance for objects that do not deviate from the size of the subject set in the area of interest and accurately extracts the texture characteristics of different subjects with similar color distribution ratios.

Purpose - This thesis aims to increase the success of Korean fashion brands in the Chinese consumer market by providing basic items in fashion colors preferred by women in their twenties and thirties, having the highest purchasing power, in Beijing and Seoul, in the summer of 2012. Research Methodology - The street fashion color data were retrieved for the case study by taking pictures and recording videos at the famous fashion streets in Beijing and Seoul. The WINDOWS SPSS 18.0 program was applied, to determine the frequency of street fashion colors. Results - The results might be ascribed to the tendency of Chinese women to favor the symbolism of traditional colors. Conversely, women in Seoul have more attachment to international fashion color trends than to the traditional color symbolism. Conclusions - This study suggests that Korean companies should consider the differences in street fashion color preferences when planning to launch a fashion brand in the Chinese consumer market. To gain the long-term perspective, further research on the local Chinese area might be essential to help Korean fashion companies and brands launch into the Chinese consumer market.

The purpose of this study is to classify the characteristics of color communication tools and the color range applied in the Korean fashion industry. To collect the color sample and related references, a questionnaire was distributed during the time period, December, 1995 to June, 1996. From the responses, 2641 color samples used by 109 domestic brands, from 1993 spring/summer to 1996 spring/summer, were collected and analyzed. The data was measured by L*a*b*, and the H V/C formula found in the Munsell notation was used to calculate the data. To classify the color range served for the fashion industry, the distribution of colors are analyzed by difference of season and fabric. The results of this study are as follows : 1. Dominant colors in the Korean fashion industry are Red, Yellow-red, Yellow, purple-blue and low chromatic range colors. 2. While high value colors, such as pale, light greyish, light, dull, dark and vivid tone colors, are dominant in the spring/summer season, low value colors, such as greyish, dark greyish. and deep tone colors and warm colors such as Red, Yellow-red, are prevalent in the fall/winter season. 3. The number of colors commonly used for color planning is less than 20 colors, and both hue and tone are considered important when making color selections. 4. All brands take consumers' color preferences into consideration for color planning, and most of them also take color trends into account. 5. Hue and tone color characteristics analyzed by types of fabrics show more seasonal influence than the fabric itself.

칼라 코렐로그램은 칼라 히스토그램처럼 픽셀의 칼라 정보만을 고려하지 않고 영상의 픽셀의 공간 정보까지 고려하기 때문에 콘텐츠 기반 영상 검색(CBIR)에서 널리 사용되어 왔다. 칼라 코렐로그램은 하나의 칼라 형태를 사용한다. 그래서 칼라 코렐로그램은 영상 검색 시 같은 영상이라도 크기가 다를 경우 다른 영상으로 인식하는 등 영상의 특징을 구별해내는데 강건하지 않다. 본 논문에서는 RGB와 HSV의 두 가지 칼라 형태를 사용하여 코렐로그램을 함으로써 기존의 알고리즘보다 영상의 특징을 더 잘 구별해내는 알고리즘을 제안하였다. 이 제안된 알고리즘은 대규모 영상 데이터베이스에서 테스트하였고 그 결과 하나의 칼라 형태를 사용한 코렐로그램 알고리즘과 비교하여 검색된 영상의 평균 순위가 5.63 낮아져 제안한 알고리즘이 더 나은 검색 성능을 나타낸다는 것을 보여준다.

기존의 색상 기반의 Mean Shift 알고리즘을 이용한 객체추적 알고리즘은 초기 색상 정보가 사라질 경우 정확한 객체추적을 수행할 수 없다. 본 논문은 객체의 색상이 변할 때 색상 정보를 변경하여 정확히 추적하는 알고리즘을 제안한다. 제안 알고리즘은 현재의 위치를 중심으로 다음 객체 위치에 해당하는 밀도가 가장 높은 위치를 Mean Shift알고리즘으로 구하고, 바꿔 색상 정보를 변경하는 반복적인 기법을 사용한다. 이를 통해 처음 설정한 객체의 색상이 바뀌거나 사라지더라도 정확한 객체추적을 할 수 있게 되었다. 본 논문에서는 제안 알고리즘을 구현하고, 실험 결과로 성능을 입증한다.

We present Subaru Near-Infrared (NIR) photometry for globular clusters (GCs) in the giant elliptical galaxy NGC 4649 (M60) belonging to the Virgo cluster. NIR data are obtained in Ks-band with the Subaru/MOIRCS, and matching HST/ACS optical data available in literature are used to explore the origin of GC color bimodality. A clear bimodal color distribution is observed in the optical color (g-z), in which the ratio between blue and red GCs is 4:6. By contrast, the more metallicity-sensitive optical-NIR colors (g-Ks, z-Ks) show a considerably weakened bimodality in their distributions. The color-color relation of the optical and NIR colors for the GC system shows a nonlinear feature, supporting that the optical color bimodality observed in NGC 4649 GC system is caused by nonlinear color-metallicity relations (CMRs).

Modern Hanbok tends to use new colors based on traditional colors and their symbolic meanings. In addition to the traditional colors, various expressions have been increased, it is necessary to consider the color and color trend used in modern clothing. This study focused on the period 2011 - 2020 and analyzed the main color and coloring method of top and skirt by year with 450 data from a total of 81 wedding magazines. The results of examining the characteristics of traditional colors during the target period are as follows. First, the main color of the Jeogori showed a distribution of various colors in the first half, but the main color of the skirt concentrated on black, white and light pink in the second half. Second, while the use of blue and green systems decreased, Dang-ui color changed to warm yellow, green, and red systems. The Baeja used plain dark white in the first half; however in the latter half, they changed to white or accented colors. The one-piece used various colors in the first half, but only black and white appeared in the second half. Third, in the upper and lower colors of Hanbok, the blue-red color, the traditional contrast color of the first half, decreased significantly in the second half. The appearance rate of proximity for the complementary color harmony of white-red color and the adjacent color harmony of white-blue increased.
