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.

This paper has been studied the adaptation technique for color vision variations in the MPEG-21 Digital Item Adaptation (DIA). As color is more widely used to carry visual information in the multimedia content, ability to perceive color plays a crucial role in getting visual information. DIA is performed respectively for severe color vision deficiency (dichromats) and for mild color vision deficiency (anomalous trichromats), according to the description of user characteristics about color vision variations. Adapted images are tested by simulation program for color vision variations so as to recognize the appearance of the adapted images in the color deficient vision. Experimental result shows that proposed adaptation technique works well in the MPEG-21 framework.

The purpose of this study is to investigate the effect of eyeshadow color (brown, purple, and blue), lipstick color (red, red purple, and yellow red), and lipstick tone (vivid, light, dull, and dark) on impression formation. Sets of stimulus and response scales (7 point semantic) were used as experimental materials. The stimuli were 36 color pictures manipulated with the combination of eyeshadow color, lipstick color, and lipstick tone using computer simulation. The subjects were 216 female undergraduates living in Jinju city. Impression factor of the stimulus was composed of 4 different components, attractiveness and gracefulness, visibility, cuteness, and softness, of which the first two were important. Eyeshadow color, lipstick color, and lipstick tone independently influenced the attractiveness and gracefulness and visibility. In the cuteness and softness, eyeshadow color and lipstick tone showed independent effect. In the interaction effect, the combination of lipstick color and lipstick tone showed significant effect on the attractiveness and gracefulness, visibility, and cuteness. Finally, it was found that the combination of eveshadow color and tpstick tone showed significant difference in the softness.

As fast-speed of aging in modern society has led to increased concern for aging and health improvement of senior citizens, desire about having healthy living-environment has also increased. Living space for senior citizens has to play role of healing for their body feature as well as decrease in mental and psychological function. Color, as important factor that supplements degenerated sense and coping ability caused by aging, it has been revealed through modern medical science that color is effective for making nervous or calming down when it is delivered to one's nerve through sight. The purpose of this study is to suggest basic resource for color arrangement palette of living space and application method by color therapy to improve seniors' mental health by considering psychological and physical features caused by aging. First, consider psychological and physical feature of seniors and color therapy effect through previous research. Second, extract RGB value after selecting color that is helpful for their mental health by using palette from 'Korea Agency for Technology and Standards'. Third, extract other 3 colors that are similar with extracted color from 'NCS 1950 Color System'. Fourth, deduct palette of 3 color arrangement by using 'NCS Navigator' program. Lastly, extract arrangement palette for them by considering difference in visual features, and then suggest arrangement application for each palette through Computer Simulation.

Various studies with regard to increasing the optical efficiency of plasmonic color filters have previously been conducted, such as mixing materials or applying diverse pattern shapes. Fundamentally, it is important to maximize the photonic crystal effect by finding the optimum periods of lattice as well as calculating the most efficient transmission area. In this study, we propose a technical method for optimizing the plasmonic color filters that have a high color gamut and luminance by analyzing the light spectrums based on the 1931 color coordinate system. Moreover, we suggest a calculation method in order to define the individual color purity of red and green and blue filters. Consequently, efficiency values are obtained independently from each color filter by evaluating the color purity and the luminance. The final result obtained from simulation are 27.6% of relative luminance and 25.3% of color gamut. The proposed optimization method is applicable to all plasmonic color filters having photonic crystal arrays.

There are no authentic solutions in a face region extraction problem though it is an important part of pattern recognition and has diverse application fields. It is not easy to develop the facial region extraction algorithm because the facial image is very sensitive according to age, sex, and illumination. In this paper, to solve these difficulties, a fuzzy color filer based on the facial region extraction algorithm is proposed. The fuzzy color filter makes the robust facial region extraction enable by modeling the skin color. Especially, it is robust in facial region extraction with various illuminations. In addition, to identify the fuzzy color filter, a linear matrix inequality(LMI) optimization method is used. Finally, the simulation result is given to confirm the superiority of the proposed algorithm.
