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.

The purpose of this study is to design appropriate digital tools for the production of makeup designs. In this study, we used a three-dimensional facial avatar simulation program developed by the Electronics and Telecommunications Research. This study is based on the creation of three-dimensional CG digital art of facial avatar makeup, produced by using simulation technology. First, the actual application and the tools for digital-optimization and media features were created, leading to the research and cleanup. Second, the theoretical background was applied to the formative elements of oriental colors in the designing process. Makeup design elements include point, line, surface, color, and texture. In this study, effective makeup design was interpreted to be based on the representation of particular elements, notably the design principles of balance, proportion, rhythm, repetition, emphasis, contrast, harmony, and unity. In Asia, design is based on the visibility of red, blue, black, yellow, and white-the colors of the five elements-and the use of points, lines, and shapes. This study was recently under scrutiny in relations to digital simulation and various three-dimensional designs, in terms of how to take advantage of a wide range of applications, and how to apply the findings through media and the dissemination of basic research. This study applies the characteristics of the limited existing stereoscopic three-dimensional and digital simulation programs in order to take advantage of the empirical research, providing a basis to implement this research in a meaningful way. A follow-up study is needed to extend these findings and theoretical foundation through continuous observation and in-depth technical development and research.

메이크업 시뮬레이션은 입력 장치와 디스플레이를 사용하여 가상의 디지털 얼굴에 다양한 화장법을 시험해 볼 수 있는 도구이다. 최근에 다양한 메이크업 스타일을 지원하는 시뮬레이션 시스템들이 개발되었지만, 대부분의 시스템들이 2차원 얼굴 영상을 사용하기 때문에 피부를 사실적으로 표현하는데 제약이 많다. 본 연구에서는 피부의 거칠기와 반사도를 조절할 수 있는 사실적인 3차원 메이크업 방법을 개발하였다. 제안 방법은 3차원 스캐너로 획득한 고해상도의 얼굴 데이터 상에서 피부 파라미터 값을 변경하면서 메이크업을 시뮬레이션할 수 있다. 또한 포인트 기반 형상표현을 사용하여 3차원 렌더링 과정을 간단하고 유연하게 표현하였으며, 얼굴 부위에 따라 반사도를 달리 적용하여 보다 사실적인 메이크업 시뮬레이션을 가능하게 하였다.

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 논문은 파우더 메이크업 효과를 시뮬레이션 하는 새로운 방법을 제안한다. 간단하면서도 사실적인 색상을 표현할 수 있는 색상 발현 모델을 고안하고, 여러 색상의 인조스킨에 파우더를 도포한 사진 이미지 분석에 색상모델을 적용하여 파우더 고유의 투과색 및 도포 두께를 추출하였다. 또한, 실제 사람 피부에 도포된 파우더 도포 두께 패턴을 추출하고 이를 다른 사람의 사진 상에서 메이크업 시뮬레이션 하는 데 사용하여 파우더의 질감을 실감 있게 표현하였다. 실험 결과 제안된 메이크업 시뮬레이션은 사실적인 색감과 질감을 나타낸 것으로 평가되었으며, 파우더 색상을 가상으로 테스트 하는 데 사용할 수 있을 것으로 기대한다.

본 시스템은 웹 상에서 가상으로 메이크업과 헤어스타일 그리고 액세서리 등을 사용자 자신의 얼굴에 적용시켜 볼 수 있는 시뮬레이션 시스템이다. 시뮬레이션의 결과는 데이타베이스에 저장되며 프린터로도 출력이 가능하다. 본 시스템은 자바 애플릿으로 제작되어 서비스가 되므로 웹 브라우저 이외의 클라이언트 프로그램은 필요하지 않으며, 웹 브라우저에 자바 플러그인만 설치되어 있으면 실행이 가능하다. 윈도 2000의 IIS 웹 서버와 MS-SQL7 데이타베이스를 이용하여 구현하였으며, 자바 애플릿과 데이타베이스의 연결은 상용화된 JDBC Driver Type 4를 이용하였다. 구현된 VMSS는 웹 기반의 서비스 제공을 위한 새로운 컨텐츠 개발의 유형을 제시하였으며, 다양한 분야에 대한 응용이 가능할 것으로 생각된다.

The purpose of this study is to investigate the effect of eyeshadow color(brown, purple), lipstick color(red, red purple, and yellow red), and lipstick tone(vivid, light, dull, and dark), clothing color(same, different), clothing tone(vivid, light, dull, and dark) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 128 color pictures manipulated with the combination of eyeshadow color, lipstick color, lipstick tone, clothing color, and clothing tone using computer simulation. The subjects were 768 female undergraduates living in Gyeongnam-do. Image factor of the stimulus was composed of 4 different components, attractiveness, visibility, stability, and softness). In the 4 image components, lipstick tone, clothing color and clothing tone showed independent effect. Eyeshadow color influenced independently on the attractiveness, visibility and stability. According to the variation of clothing color and tone, makeup color, it was investigated that the images for a clothing wearer were expressed diversely, were shown differently in image dimensions, and could be produced to different images.

The purpose of this study is to investigate the effects of eye shadow color(brown, purple), lipstick color(red, red purple, and yellow red), and lipstick tone(vivid, light, dull, and dark) and clothing tone(vivid, light, dull, and dark) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli consisted of 64 color photos manipulated with the combination of eye shadow color, lipstick color, lipstick tone, and clothing tone using computer simulation. The subjects were 384 female undergraduates living in Gyeongnam Province. Image factor of the stimulus was composed of 4 different components: attractiveness, visibility, cuteness, and stability. Eye shadow color, lipstick tone and clothing tone independently influenced on visibility, cuteness, and stability. Lipstick color independently influenced on the stability. In color coordination of clothing and makeup of the same hue, 1) visibility image can be created by the coordination of eye shadow color with lipstick color or clothing tone, or lipstick color with lipstick tone. 2) Cuteness image can be produced by the coordination of eye shadow color with lipstick or clothing tone, lipstick color with lipstick or clothing tone. 3) Stability image can be showed by the coordination of eye shadow color with lipstick tone.
