Simulating color appearance of makeup effect is an important issue in computer graphics as well as cosmetic industry. Most of previous works on makeup simulation are simple color blending to mimic the cosmetic effects. Some of previous works employed Kubelka-Munk model to accurately simulate the layering effect of cosmetics. However, the simulation limited on single point, and the rest of area are still computed by simple color blending utilizing the color of the single point simulation. This paper presents an image-based method to compute the color appearance effect of makeup application using per-pixel Kubelka-Munk model. Unlike the previous methods, it is possible to compute per-pixel application thickness as well as optical property of cosmetics. The computed thickness pattern can be used in makeup simulation for a more realistic makeup simulation.

A computer simulation was performed to distinguish quantitatively a color reaction in a urine analysis systems by using the spectral power distribution of LEDs, the spectral reflectance of a urine strip, and the spectral sensitivity of photodiode. The CIE tristimulus values and CIE chromaticity coordinates ware modified to be conformable with real color reactions in a urine strips. Results on color simulation showed a of real color in comparison with those obtained by Colorimeter CM2C(Color Savvy).

A color is the most important of all factors that have influence on interior spaces, and plays an visually and psychologically important role in making interior environment. Thus, the aim of this study is to propose predictable color models by image types specially for color design in living room.This study was composed of three steps, and was carried out as follows.1) The evaluation experiment was carried out by color simulation using Color Image Processor. 2) Image types were extracted by factor analysis. 3) The characteristics of colors by image types were analysed by the multi regression and as a result the predictable color models by image types was determined.

Color simulation on a portable colorimeter was performed to distinguish quantitatively a chromaticity coordinates on a color guide of a urine strips by using the spectral power distribution of chip LED, the spectral reflectance of printed objects, and the spectral sensitivity of photodiode. The CIE tristimulus values and chromaticity coordinates realized by a colorimeter were modified to be conformable with real color reactions. Experimental results showed a real color in comparison with those obtained by Colorimeter CM2C(Color Savvy).

This study aims to propose directions of color-scape about fishing village and harbor in East coast. In order to offer better landscape in harbor; Namae and Sachun, such as regional atmosphere and identification are to analyze with color planning. For the quality of color-scape, natural color, regional color of harbor may be possible to work out future harbor surrounding by evaluation scale and then hue, value, chroma can be estimated systematically. This survey suggests that color of harbor is to be environmental and regional color control. We analyze that the color-scape planning through the both whole harmony and organic combination is important elements of satisfaction to the people of experience with color environments. Consequently, some proposal of color guideline by analysis of color simulation will be useful to make out preliminary design criteria in improvement of color.

Nanosize cobalt aluminate($CoAl_2O_4$) power was coated as filter layer for us to improve the color purity and contrast performances on the inner face of CRT panel. We simulated color properties by measuring the transmittance and thickness of the coated filter layer. Contrast performance could be improved and color gamut was also changed by the selective light absorption of filter layer at 580${\sim}$605 nm.

Various simulation applications for hair, clothing, and makeup of a 3D avatar can provide more useful information to users before they select a hairstyle, clothes, or cosmetics. To enhance their reality, the shapes, textures, and colors of the avatars should be similar to those found in the real world. For a more realistic 3D avatar color reproduction, this paper proposes a spectrum-based color reproduction algorithm and color management process with respect to the implementation of the algorithm. First, a makeup color reproduction model is estimated by analyzing the measured spectral reflectance of the skin samples before and after applying the makeup. To implement the model for a makeup simulation system, the color management process controls all color information of the 3D facial avatar during the 3D scanning, modeling, and rendering stages. During 3D scanning with a multi-camera system, spectrum-based camera calibration and characterization are performed to estimate the spectrum data. During the virtual makeup process, the spectrum data of the 3D facial avatar is modified based on the makeup color reproduction model. Finally, during 3D rendering, the estimated spectrum is converted into RGB data through gamut mapping and display characterization.

본 논문에서는 단소자 적외선 레티클 탐색기의 단점을 해결하기 위해 적외선의 두 대역을 이용하는 2-color 회전 동심원 레티클 탐색기(concentric annular ring reticle seeker)의 시뮬레이션 툴이 제안된다. 표적 및 섬광탄(flare)의 모델링과 비례항법 유도(proportional navigation guidance) 루프를 포함한 동적인 시뮬레이션 툴 상에서 동심원 레티클 탐색기의 추적 성능과 섬광탄에 의한 영항 등을 분석한다. 또한 다양한 상량에서 운용되는 섬광탄의 영향을 효과적으로 배제하기 위해 LMS 방법을 이용한 새로운 반대응능력(counter-countermeasure)이 제안된다. SWIR 및 MWIR 대역에서 표적과 섬광탄의 상대적 분포특성을 이용함으로써 섬광탄에 효과적으로 대처할 수 있으며, 교전 시나리오에서 기존 반대응 기법과의 비교를 통해 제안된 알고리즘의 향상된 추적 성능을 확인하였다.
