The purpose of this study is to investigate the emotional image, preference and purchasing intention about the arrangement of colors according to brightness difference of gray color applied to the cardigan. Pattern was used Queen Mureying's diadem pattern in the applying aspects of traditional patterns. The subjects were 604 university students in Daejeon and Chungnam province, and the measuring instruments were 10 stimuli manipulated by color and brightness combination of ground and pattern, self-administered questionnaires consisted of emotional images items, preferences and purchasing intention items, personality items, and subjects' demographics attributions. The data were analyzed by descriptive statistics, factor analysis, Cronbach's α, ANOVA, MANOVA and Duncan's multiple range test, using SPSS program. The results were as follows. The first, four factors(attractiveness, visibility, mildness, and activity) were emerged on emotional images of knitwear. The second, as ground color of cardigan, the gray of high brightness was perceived more attractively, mildly and actively than gray of low brightness. The third, the red of pattern was perceived by more distinct color than blue or gray. Forth, female felt more mildness on same cardigan than male. Fifth, introvert showed higher preferences and purchasing intention about the gray ground color cardigan than extrovert. Sixth, cardigan preferences were influenced by pattern color on depending on the gender of the subjects. High brightness color of pattern was preferred by female, but low brightness color of pattern was preferred by male.

Inverse color to black-and-white halftone conversion via dictionary learning and color mapping

Son, C.H.,Lee, K.,Choo, H. Elsevier science 2015 Information sciences Vol.299 No.-

This paper challenges the problem of estimating the original red-green-blue (RGB) image from a black-and-white (B&W) halftone image with homogeneously distributed dot patterns. To achieve this goal, training RGB images are converted into color-embedded gray images using the conventional reversible color to gray conversion method, and then converted into halftone images using error diffusion in order to produce the corresponding B&W halftone images. The proposed method is composed of two processing steps: (1) restoring the color-embedded gray image from an input B&W halftone image using a sparse linear representation between the image patch pairs obtained from the images and (2) restoring the original colors from the color-embedded gray image using the reversible color to gray conversion and linear color mapping methods. The proposed method successfully demonstrates the recovery of colors similar to the originals. The experimental results indicate that the proposed method outperforms the conventional methods. It is suggested that our method is not only successfully applied for the color recovery of the B&W halftone image, but that it can also be extended to various applications including color restoration of printed image, hardcopy data hiding, and halftone color compression.

This study aims at offering some theoretical foundations and at helping choose the proper white balance setting, by comparing and analyzing the characteristics of the automatic white balance setting, with which digital cameras and RWA file converting programs are equipped, and the characteristics of the custom white balance setting, using a gray card, a white card, and etc. For this analysis, Kodak gray scale (large) Q-14, Kodak color control patches Q-14, Macbeth color checker, a Fotowand gray card, and a Fotowand white card were used, with automatic white balance setting and with custom white balance setting respectively, and also with the speed light of less color temperature changes. Also, the image reproducibility, such as the changes of image tone, color representation, chroma, noise density, and dynamic range, was analyzed through Photoshop CS3 and through Imatest-1.6.16. The analysis results showed that when the same algorism was applied to, it brought about various results, but some characteristics of each case and some minute comparative superiority of setting were found, while the products of one company had different features and it was difficult to find just one rule with one model. As for the color tone, generally, when a gray card was used and the coloration of neutral gray was reproduced nicely, the white color was represented with a warm feeling, and when a white card was used and the coloration of the white color was nice, the neutral gray was represented with a cold feeling. When a white card was set up, the error range of white balance was smallest, and therefore it would be much better to set up a white card to photograph a bright subject, in particular, such as a white background or an achromatic color. This study contributed to theorizing the mostly used settings through objective experiments, in spite of its limitation of the application of the same algorism.

Personal color emphasizes the importance of color as a concept that can be applied to the body by supplementing the body's weaknesses that change with age and capitalizing on its strengths. Therefore, facial wrinkles, melasma, and freckles caused by aging can become darker or lighter depending on selection of personal color. The degree of interest in the personal color system and the effect on image change and satisfaction after dyeing personal color gray hair were examined in this study. In this study, both online and offline surveys that included both males and females who had undergone gray hair dyeing at least once through personal color diagnosis were conducted, and 487 copies were used for the final analysis. Frequency analysis, exploratory factor analysis, independent sample t-test, one way ANOVA, and regression analysis were performed for analysis of data in this study. According to the results of this study, the overall interest in personal color was lower than the normal level, indicating that the provision and utilization of various information in the field of hair beauty will be required in the future. In addition, regarding personal color interest, relatively higher overall personal color interest and personal color application by sub-factor was observed for females compared with males, suggesting the need for male customers' awareness and application. As interest in personal color increases, establishment of standards for marketing and demand setting for the customer base in the personal color application market may be necessary.

도료로 표현한 Gray의 색채 감성연구 - 중명도 Gray를 기준으로 -

This study was focused on considering paints as a world of color expressions beyond chemical or physical approaches and verifying the possibility to diversify color sentiment images through color samples developed herein. Despite constraints like color gamut limited to mid-bright gray through naked eye observation, and the expression techniques only for aesthetical effects using paints for plastic, gray color sentiments extracted from experiment were analyzed in ways as diverse as other color sentiments. Conclusively, it was possible to make a limited color like gray induce an extra-wide range of color sentiments. And this study came to finding about possibility of gray color to diversify color sentiments through differentiation of color expression elements or methods.

개선된 영상생성 모델과 적응적 필터를 이용한 칼라 영상 보정방법

최호형,윤병주 한국콘텐츠학회 2009 한국콘텐츠학회논문지 Vol.9 No.12

Color rendition method is necessary for improving the low contrast images which are achieved by PDA, mobile phone camera or PC camera. There are some methods for color rendition. However, after correcting the color, image quality degradations, such as graying-out, halo-artifact and color noise, may occur. In order to overcome these problems, this paper proposes a retinex-based color rendition method. The proposed method uses the HSV color coordinate system to avoid the graying-out, and the advanced image formation model to reduce the halo-artifact in which the image is divided into three components as the global illumination, the local illumination, and reflectance. The experiment results show that the proposed method yields better performance of color correction over the conveniently method. 일반적으로 PDA, 모바일 폰 카메라, PC 카메라 등으로 촬영된 영상은 촬영 장비의 생동 폭의 한계로 인해 낮은 영상 대비를 갖는 영상들이 획득된다. 이러한 이유로 영상 개선 방법은 여러 가지의 영상 촬영 장비를 이용해 촬영된 영상들의 개선을 위해 필요하다. 영상 개선을 위한 몇 가지의 방법들이 제안되었으나, 후광효과(halo-artifact), 회색계의 왜곡(graying-out), 칼라 잡음(color noise) 등의 영상 왜곡이 발생한다. 이러한 문제를 해결하기 위해, 본 논문은 레티넥스 기반 영상 향상 방법을 제안하며, 회색계의 왜곡을 줄이기 위해 HSV 칼라 좌표계를 사용하며, 후광효과를 줄이기 위해 영상을 전역조명성분, 국부조명성분, 반사성분으로 나누는 개선된 영상 생성모델을 적용한다. 실험 결과는 제안한 방법이 다른 방법들 보다 성능이 우수함을 보여준다.

본 연구는 제주마에서 빈번하게 관찰되는 전신성 백모색 발생의 유전 양상과 유전적 변이와의 상관을 구명하기 위해 수행하였다. 백모색은 표현형과 MC1R 유전자형 분석 자료의 조합을 근거로 결정한 가라, 유마, 적다 등 모든 기본 모색에서 관찰되었다. 제주마에서는 타 품종들에서 KIT 유전자의 이형접합성에 의해 발생하는 선천성 백색에 대한 잠재적 돌연변이들은 발견되지 않았다. STX17 유전자의 intron 6에서 4.6-kb 중복을 보유한 개체들에서 특이적으로 탈색된 백모색이 관찰되었다. 관찰기록과 STX17 유전자형에 따라 제주마에서 관찰되는 탈색된 백화현상은 총마(점진적 백화증, Gray)로 확인되었다. 가계도 분석에서 총마 형질은 상동염색체성 우성유전형질로 나타났으며 상동염색체성 열성형질인 albinism과도 구분되었다. 제주마에서 총마 모색이 자마 시기에는 명확하게 발현되는 않으며, 종종 다른 표현형들과 혼동을 일으키기도 하기 때문에, 총마와 이와 유사한 표현형으로 출생 시부터 혼합 모색을 나타내는 조모색, 상처 치료 후 백화, 백반 유사피부 백색증 등에 대한 추가 연구가 요구된다고 하겠다. 그럼에도 불구하고 총마와 유전적 배경의 관계를 구명한 본 연구결과는 제주마에서 분자육종을 위한 유용한 정보를 제공할 것으로 사료된다. This study was undertaken to reveal the relationship between genetic variations and inheritance patterns and the development of a systemic white coat color frequently observed in Jeju horses. It was determined that the white coat color occurred in all basic coat colored (black, bay and chestnut) horses by combining the phenotype and MC1R genotypes. There were no polymorphisms found in Jeju horses tested for mutational loci in the KIT gene, which were previously reported as potential mutations of the congenital dominant white coat color in other horse breeds in heterogeneity. The horses that had the 4.6-kb duplication in the STX17 intron 6 specifically showed the depigmented white coat color. Based on observation and STX17 genotypes, this depigmented whitening is defined as ‘Chongma' (whitening, progressive graying with age-Gray) in Jeju horses. Pedigrees showed that this is an autosomal dominant inheritance pattern distinct from the bovine albinism caused by an autosomal recessive passion eye color. Because the gray phenotype is generally not completely expressed early in Jeju horses, it often makes them indistinguishable from other horses. Further studies are recommended for classification between the gray coat color and its similar phenotypes, such as the roan with its mixed hair colors appearing since neonatal period, acquired white hairs on wounded skin by veterinary treatment, and vitiligo-like skin pigmentation. However, study results revealing the relationship between the gray phenotype and genetic background suggested that useful information may be provided in regards to molecular breeding of Jeju horses.
