Inspired by the increasing popularity of cosmetic-related mobile application as a tool for instant beautification, the present study examined colors of virtual makeup templates and makeup looks. A survey study was performed by thirty-six respondents to determine the top three desirable virtual makeup templates among nineteen templates. The templates of 'Bella', 'Hilary' and 'Cara' were then analyzed by makeup specialists and color experts for the evaluation of their makeup design and colors. Each color feature of three makeup templates were also evaluated through statistical analysis of ANOVA on the measure of $L^*a^*b^*$ crossed with five types of face elements on three types of virtual makeup images. Overall results indicate that Korean female users in their 20s and 30s preferred a similar makeup concept appeared in makeup template and key worlds. They also preferred a pale skin tone with higher lightness and a slightly higher saturated lip color as an emphasis than other features.

This study is a study that analyzes the user experience of a virtual makeup application in the beauty industry where color or formulation testing is important. Recently, cases of beauty smart stores and beauty applications using AR and AI are increasing. However, since virtual makeup is different from testing a real product, it is necessary to derive needs through research from the user's side. In order to compare user preferences by using AR and AI cases, six factors based on the emotional interface model were analyzed through a questionnaire to identify items with statistically significant figures. As a result, the user felt comfortable with the virtual makeup function, but showed that it needs to be supplemented in terms of reliability. Since this study focused on the customer experience as a real user and identified the main experience factors and needs of virtual makeup through two types of comparison, it is hoped that this study will be useful as a prior study.

본 논문에서는 햅틱 인터랙션 기반의 3차원 가상 얼굴 메이크업 시뮬레이션에서 메이크업 대상에 대한 정교한 페인팅을 적용하기 위한 자동화된 마스크 생성 방법을 개발한다. 본 연구에서는 메이크업 시뮬레이션 이전의 전처리 과정에서 마스크를 생성한다. 우선, 3차원 스캐너 장치로부터 사용자의 얼굴 텍스쳐 이미지와 3차원 기하 표면 모델을 획득한다. 획득된 얼굴 텍스쳐 이미지로부터 AdaBoost 알고리즘, Canny 경계선 검출 방법과 색 모델 변환 방법 등의 영상처리 알고리즘들을 적용하여 마스크 대상이 되는 주요 특정 영역(눈, 입술)들을 결정하고 얼굴 이미지로부터 2차원 마스크 영역을 결정한다. 이렇게 생성된 마스크 영역 이미지는 3차원 표면 기하 모델에 투영되어 최종적인 3차원 특징 영역의 마스크를 레이블링하는데 사용된다. 이러한 전처리 과정을 통하여 결정된 마스크는 햅틱 장치와 스테레오 디스플레이기반의 가상 인터페이스를 통해서 자연스러운 메이크업 시뮬레이션을 수행하는데 사용된다. 본 연구에서 개발한 방법은 사용자에게 전처리 과정에서의 어떠한 개입 없이 자동적으로 메이크업 대상이 되는 마스크 영역을 결정하여 정교하고 손쉬운 메이크업 페인팅 인터페이스를 제공한다.

In this study, an augmented reality-based make-up tool was built to analyze the user's face shape based on face-type reference model data and to provide virtual makeup by providing face-type makeup. To analyze the face shape, first recognize the face from the image captured by the camera, then extract the features of the face contour area and use them as analysis properties. Next, the feature points of the extracted face contour area are normalized to compare with the contour area characteristics of each face reference model data. Face shape is predicted and analyzed using the distance difference between the feature points of the normalized contour area and the feature points of the each face-type reference model data. In augmented reality-based virtual makeup, in the image input from the camera, the face is recognized in real time to extract the features of each area of the face. Through the face-type analysis process, you can check the results of virtual makeup by providing makeup that matches the analyzed face shape. Through the proposed system, We expect cosmetics consumers to check the makeup design that suits them and have a convenient and impact on their decision to purchase cosmetics. It will also help you create an attractive self-image by applying facial makeup to your virtual self.

In this paper, facial feature areas in user picture are created by facial feature points extracted by ASM(Active Shape Model). In a existing virtual make-up application, users manually select a few features that are exactly. Users are uncomfortable with this method. We propose a virtual makeup application using ASM that does not require user input. In order to express a natural makeup, the modified alpha blendings for each cosmetic are used to blend skin color with cosmetic color. The Virtual makeup application was implemented to apply Foundation, Blush, Lip Stick, Lip Liner, Eye Pencil, Eye Liner and Eye Shadow.

메이크업 시뮬레이션은 입력 장치와 디스플레이를 사용하여 가상의 얼굴에 다양한 화장법을 시험해 볼 수 있는 도구이다. 최근 다양한 환경을 고려한 여러 메이크업 시뮬레이션이 개발되었지만, 대부분의 시스템은 2차원 영상에서 이루어지며 제한된 조건에서의 시뮬레이션 결과만 확인할 수 있다. 본 연구에서는 측정된 피부의 거칠기와 반사도를 적용하고 적용된 반사도를 조절할 수 있는 사실적인 메이크업 시스템을 개발하였다. 개발된 시뮬레이션 방법을 사용시 3차원 스캐너로 획득한 고해상도의 얼굴 데이터 상에서 측정된 반사도를 사용하여 빛을 고려한 메이크업을 시뮬레이션 할 수 있다. 정점 기반 형상표현을 사용하여 3차원 모델의 렌더링 과정을 간단하고 유연하게 표현하였으며, 반사도를 얼굴 부위에 따라 달리 적용하여 보다 사실적인 메이크업 시뮬레이션을 가능하게 하였다. 또한 사용자에게 반사도를 직접 조절 가능하게 함으로서 보다 사실적인 3차원 메이크업을 가능하게 하였다.

Makeup simulation is a tool that tests various makeup methods on a virtual digital face using input and display devices. Although several simulation systems supporting various makeup styles have been recently developed, most systems have many limitations on realistic skin representations because they use 2D facial images. We develope a realistic makeup simulation method which can control skin reflectance and roughness parameters. The method allows a user to simulate makeup applications while changing skin parameters using high-resolution facial data acquired by 3D scanners. Besides we use a point-based shape representation which enables simple and flexible 3D rendering, and provide a more realistic makeup simulation by applying different skin parameters on each part of the face.

This paper presents a novel makeup simulation method for powder application. We propose a color appearance model for powder coated skin that is simple but yet capable of producing realistic visual results. From the photos of several artificial skins before and after powder application, the translucency and thickness parameters are achieved by fitting the color model to the photos. Thickness patterns of powder application on actual human face skin is also extracted, and used in makeup simulations on photos of different human face to give more visually appealing results. From experiments, we found that the simulation results are quite realistic, and expect that the proposed makeup simulation can be used as a virtual coloring test in the cosmetic labs.

The VMSS(Virtual Makeup Simulation System) is a virtual simulation system which can apply makeup, hair style, accessory to user's own face image through internee connection. The simulation result can be stored to server side DB and also can be printed out on client side printer. It is implemented using Java so, clients don't need any other client program to run the VMSS except Web browser and Java Plug-in installed on browser. IIS (Internet Information Server) Web server of Window 2000 and MS-SQL 7 are used to develop the overall system. Commercial JDBC Driver Type 4 is used to connect the applet and DB. It suggests a new direction of Web-based contents service development and can be applied to many other areas.
