영화는 흑백영화부터 컬러영화로 접어들면서 스크린영상이 질적인 변화를 가져왔다. 영화 속의 색채는 물상의 객관적인 모습을 원한재현기능을 가지고 있을 뿐만 아니라 다른 주관적인 감정을 전달하는 기능도 가지고 있다. 색채 외에는 표현할 수 없는 예술적인 효과를 표현할 수 있고 스토리 자체가 전달하지 못하는 컨텐츠도 전달할 수 있다. 그러므로 영화색채는 영화언어의 중요한 구성요소가 되었다. 영화 속에 색채는 단화면색채, 신색채, 영화전체의 색채기조 및 줄거리에 따라 만드는 여러 가지 색채체인으로 스크린에서 나타났다. 영화예술 수법은 몽타주조법을 사용해서 화면 속에 색채도 몽타주형식이 형성되며 이것이 색채몽타주라고 부른다. 대중들이 색채에 주관적인 평가가 색채언어에 대한 받아들인 수준은 각 부분적인 색조사이에 상호작용에 의해 표현할 수 있다. 색채의 독특한 속성은 색채가 구조상태에 들어가야 하는 것을 결정하였다. 그래야 색채의 고유한 매력을 표현할 수 있다. 영화색채가 이런 '색채구조'의 층면에 들어가야 진정한 신미가치를 가질 수 있다. 본문은 동서양감독들의 색채사유와 동서양 영화색채에 담고 있는 문화의 차이 두 가지 측면을 통해 동서양영화 색채에 대해 비교적 연구를 하고자 한다. 서양감독들은 색채의 구조성을 강조하여 색조몽타주방식으로 인물의 감정을 표현하는 것을 중시하며 주관적 색채를 부여하는 특징을 구체적으로 드러낸다. 중국영화의 경우는 제5대 감독으로부터 영화색채언어의 새로운 장이 열리기 시작한다. 감정과 경치가 서로 융화하다가 '의상합일'의 영화 특징을 알렸다.

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.

Purpose: This study was designed to investigate the present conditions of illumination techniques in dental clinics in order to contribute improvement of operating environment. This study also aimed exploring qualitative and quantitative luminous intensity required for color temperature in dental clinic illumination, which was a critical part of esthetic dentistry. Materials and methods: A total of forty-eight local dental clinics were selected for sampling a) luminous intensity, and b) color temperature. The author measured the luminous intensity and the color temperature with lux meter and color meter respectively between 12pm and 2pm. The dental unit chair placed in the general operation positions were kept the distance 60 cm then all dental units were measured three times and averaged. The author measured the luminous intensity and color temperature with both common dental operating light and then without operating light in different office environments. The study was conducted under three conditions: 1 artificial illumination in clear day light 2. artificial illumination in cloudy day light, and 3. artificial illumination alone. Results : The results obtained were as follows. 1. The average luminous intensity in dental clinic lighting was 425 lux which was not sufficient to produce the optimal shade of the patient's teeth. Furthermore, the average luminous intensity even in full operating lighting was 9532 lux which fell short of the required level of 10,000 lux. 2. The average color temperature of all dental clinics surveyed was 5169 K which met the optimal range. However, only 33.3% fell in the correct region between 5,000-5,500 K as 25% were over 5,500 K and 41.6% were below 5,000 K. As a result, 66.7% were under insufficient color temperature conditions. 3. The dental unit chair placed next to a window, hence exposure to natural lighting, had significantly higher luminous intensity and color temperature compared to the dental unit chair which didn't have a window or natural lighting. 4. The data analysis revealed that only 6.3% of the dental clinic were met the standard of the average luminous intensity and color temperature.

The purpose of this study is to provide for the basic data useful to designing a scientific and systematic merchandising program for infants' wear brands. For this purpose, designer and MD working for 8 local infants' wear brands were surveyed to analyze the conditions of their designing and merchandising of infants' wears. The results of this study can be summarized as follows; 1. Only 3 brands employed MD for their merchandising departments. The average number of clothing designers employed by the subject brands was 3-5, while that of colorists was 1-2, and that of accessory designers was 2-3. On the other hand, the average number of patternmakers employed was about 1, while that of sewer was 4. 2. Many of the sample infants' wear brands tended to collect and analyze the information for merchandising, while most of them relied less on outside planned data. The information source upon which they relied most was 'local and foreign fashion magazine', followed by 'data surveyed by local and foreign department stores' and 'data surveyed for local fabric markets' in their order. Meanwhile, the main color represented 70-90% of the total colors, while the pastel groups accounted for 30-40% and vivid color groups for 40-50%. On the other hand, knit accounted for about 60% of their materials, while woven and sweater accounted for 30% and 10%, respectively. 3. In overall terms, most of brands felt that their brands were preferred as much as or less than their competitive brands, while consumers felt expensive for infants' wears. Namely, most consumers were dissatisfied with the price levels of infants' wears. On the other hand, consumers were found to favor the pastel color groups a little more, while being aware of each brand's sizes more or less precisely. 4. The medium upon which the infants' wear brands depended most for their advertisement was 'magazine', followed by 'radio' and 'catalogue' in their order. Most of them were analyzing the results of their sale turnover monthly or frequently in order to review their sales performances in comparison with their competitors. Most of brands bothered to program a sale strategy 4 times a year, primarily to dispose the stocks or find a breakthrough for their sales activities.

A tongue shows physiological and clinicopathological changes of inner organs. Visual inspection of a tongue is not only convenient but also non-invasive. To develop an automat ic tongue diagnosis system for an objective and standardized diagnosis, the separation of the tongue are a from a facial image and the detection of coatings, spots and cracks are inevitable but difficult since the colors of a tongue, lips, and skin in a mouth as well as those of tongue furs and body are similar. The propose d method includes preprocessing with down-sampling and edge enhancement, over-segmentation, detecting positions with a local minimum over shading from the structure of a tongue, and correcting local minima or detecting edge with color difference. The proposed method produces the region of a segmented tongue, and then decomposes the color components of the region into hue, saturation and brightness, resulting in classifying the regions of tongue furs(coatings) into kinds of coatings and substance and segmenting them. Spots are detected by using local maxima and the variation of saturation, and cracks are searched by using local minima and the directivity of dark areas in brightness. The results illustrate the segmented region with effective information, excluding a non-tongue region and also give us accurate discrimination of coatings and the precise detection of spots and cracks. It can be used to make an objective and standardized diagnosis for an u-Healthcare system as well as a home care system.

The local environmental effects on the triggering of active galactic nucleus(AGN) activity has been studied with many authors, but there still be controversy. We perform statistical analysis for nearby(0.01 < z < 0.05) volume limited(Mr < -19) samples with visual inspection based on Sloan Digital Sky Survey Data Release7. We inspect ~60,000 galaxy images visually to find peculiar objects which show not only ongoing merging features and tidal features, but also post merging features like ring or shell structures. We found that these peculiar features were shown at least 2 times more frequently among AGN host galaxies than non AGN galaxies, and this trend was still visible when galaxy properties such as color or stellar mass are fixed. Furthermore, L[OIII] and L(Ha) of peculiar galaxies are found to be more increased than those of normal galaxies. In order to ensure this results, we also checked it for a smaller subsample with ~2mag deeper monochromatic images provided from SDSS Stripe82 database, and found consistent results. At last, we perform the same work for pair(r_p<80kpc/h, delta_v<200km/s) systems. Because of some pair systems which do not interact gravitationally in actuality but fulfill the criteria for identification of pair system, the trends are found to be slightly weaker. We also found that line luminosities are increased consistently as projected distance between central and companion galaxy decreased, and as companion color gets bluer. Overall, the results of this study tell us that the local environment of galaxies affect the frequency as well as the strength of AGN activity. Local environmental effects, however, may not be the dominant triggering mechanism for AGN activity since the majority of peculiar galaxies are non AGN galaxies.

This paper presents a novel face recognition algorithm based on the deep convolution neural network and key point detection jointed local binary pattern methodology to enhance the accuracy of face recognition. We firstly propose the modified face key feature point location detection method to enhance the traditional localization algorithm to better pre-process the original face images. We put forward the grey information and the color information with combination of a composite model of local information. Then, we optimize the multi-layer network structure deep learning algorithm using the Fisher criterion as reference to adjust the network structure more accurately. Furthermore, we modify the local binary pattern texture description operator and combine it with the neural network to overcome drawbacks that deep neural network could not learn to face image and the local characteristics. Simulation results demonstrate that the proposed algorithm obtains stronger robustness and feasibility compared with the other state-of-the-art algorithms. The proposed algorithm also provides the novel paradigm for the application of deep learning in the field of face recognition which sets the milestone for further research.

This study concerns (i) Botanical characterization of local almond ecotype named "Beldi" based on flowering period and flowers color measurements (ii) Chemical characterization of almond oil such as acidity and peroxide index and specific UV absorbance values (K232 & K270). The color results of 100 flowers analyzed by chromameter shows two different color categories. The first is very light pink to whitish ($L^*=81.58$, $a^*=7.43$, $b^*=8.06$). The second is a dark pink ($L^*=71.64$, $a^*=18.34$, $b^*=4.97$) with a difference in color between the two categories ${\Delta}E=15.07$. Compared to Ferragnes/Ferraduel varieties, Beldi almond kernel has almost a comparable oil yield but different acidity and peroxide values which are 0.81%, $8.12meq/O_2/kg$ and 0.40%, $16.39meq/O_2/kg$ respectively.
