Representative achievements

· Biological Properties-based Artificial Scar Synthesis using Inverse Lighting :

The present study proposes a method to extract and apply biological properties to naturally realize a scar texture on the skin. The ratio of melanin to hemoglobin in the skin, which determines inter- and intra-individual variations in skin appearance, is extracted as a biological property. First, a color table is defined using parameterized biological properties. Using an inverse-lighting equation that we define, biological parameters and rendering parameters are extracted from a single obtained or downloaded scar image without taking a picture of a scar directly. The extracted parameters are used to realize the most appropriate scar on the actual skin. To express the geometric depth of the scar, a tessellation process is employed. Finally, we provide the experimental results from the evaluation of our method. https://youtu.be/5qJ8QvMLY8I

· Structural Motion Grammar for Universal use of Leap Motion: Amusement and Functional Contents Focused :

Motions using Leap Motion controller are not standardized while the use of it is spreading in media contents. Each content defines its own motions, thereby creating confusion for users. Therefore, to alleviate user inconvenience, this study categorized the commonly used motion by amusement and functional contents and defined the Structural Motion Grammar that can be universally used based on the classification. To this end, the Motion Lexicon was defined, which is a fundamental motion vocabulary, and an algorithm that enables real-time recognition of Structural Motion Grammar was developed. Moreover, the proposed method was verified by user evaluation and quantitative comparison tests.

· Virtual Figure Model Crafting with VR HMD and Leap Motion :

Handcrafting has been used for purposes ranging from learning and entertainment to stress relief. However, clay art and handicrafts require specialized space and physical materials. In this paper, we propose a virtual figure model crafting system (VFMC) that is developed to allow users to directly experience the figure model crafting process using a head-mounted, display-based, virtual reality environment. In the proposed system, users can freely generate the shape of a figure and decorate its exterior. In  order to provide realistic crafting user experiences, we leverage motion grammar-based gestural input with Leap Motion and consider the support of multiple difficulty levels for user engagement. The preliminary user study results confirm that the proposed system provides immersive and interactive crafting experiences in a virtual environment. https://youtu.be/LUiA4StF1lo

· Multi-layer Structural Wound Synthesis on 3D Face :

In this research, we propose multi-layer structural wound synthesis on a 3D face. The fundamental knowledge of the facial skin is derived from the structure of tissue, being composed of epidermis, dermis, and subcutis. The approach first defines the facial tissue depth map to measure details at various locations on the face. Each layer of skin in a wound image has been determined by hue-based segmentation. In addition, we have employed disparity parameters to realise 3D depth in order to make a wound model volumetric. Finally, we validate our methods using 3D wound simulation experiments. https://youtu.be/nn7OtAPg2Nc

· Novel real-time wound recovery synthesis on a 3d face using subsurface scattering :

In this approach, we propose a model of wound contraction and multi-layered skin shading, which represents wound healing on a 3D face. A wound is normally recovered in four phases, namely, hemostasis, inflammatory, proliferative, and remodeling. In order to represent the recovery of a wound, the H3 model is used for determining the size of the wound, which is in the middle of the healing process. Further, to realize color transformation of a wound, our subsurface scattering of the wound is designed to take into consideration multi-layered skin structures of the wound. Finally, we validate our methods using 3D wound simulation experiments with shading models. https://www.youtube.com/watch?v=nIaSFE_X3Xo

· Novel irregular mesh tagging algorithm for wound synthesis on a 3D face :

Recently, advanced visualizing techniques in computer graphics have considerably enhanced the visual appearance of synthetic models. To realize enhanced visual graphics for synthetic medical effects, the first step followed by rendering techniques involves attaching albedo textures to the region where a certain graphic is to be rendered. For instance, in order to render wound textures efficiently, the first step is to recognize the area where the user wants to attach a wound. However, in general, face indices are not stored in sequential order, which makes sub-texturing difficult. In this paper, we present a novel mesh tagging algorithm that utilizes a task for mesh traversals and level extension in the general case of a wound sub-texture mapping and a selected region deformation in a three-dimensional (3D) model. This method works automatically on both regular and irregular mesh surfaces. The approach consists of mesh selection (MS), mesh leveling (ML), and mesh tagging (MT). To validate our approach, we performed experiments for synthesizing wounds on a 3D face model and on a simulated mesh.

· Optimal Model of Optical Parameter Extraction for Material Rendering :

Material rendering has been actively studied in the graphics field. To express human skin or various materials realistically, shading technology that can reflect the physical features of a material is needed. The core factor in rendering is optical parameters, and the accuracy of these parameters based on the material’s optical features determines the rendering quality. The parameters required for rendering are extracted with a spectrographic optical shooting device and by curve fitting. Existing processes for parameter extraction require significant time. To overcome this disadvantage, we produced an HDRI (high dynamic range image) generating program with exposure fusion algorithm. The number of LDRIs (low dynamic range images) for an HDRI was optimized through an experiment. In addition, the amount of sample data, which mostly affect extraction time in automated systems, can be optimized to reduce time loss during the photo-shoot, fusion and extraction processes. https://youtu.be/UKph8VWTeDg

· Method of combining spectrophotometer and optical imaging equipment to extract optical parameters :

Optical parameters of materials are used for implementing cinematic rendering in the field of graphics. Critical elements for extracting these optical characteristics are the accuracy of the extracted parameters and the required time for extraction. In this paper, a novel method for improving these elements and a comparison to the existing methodology is presented. By using a spectrophotometer and custom designed optical imaging equipment (OIE), our method made it possible to enhance accuracy and accelerate computing speed by reducing the number of unknowns in the fitting equations. Further, we validated the superiority of the extracted optical characteristic parameters with a rendering simulation. https://www.youtube.com/watch?v=tav7d2p7KWY

·   Subsurface scattering-based object rendering techniques for smartphone games :

Subsurface scattering that simulates the path of a light through the material in a scene, is one of the advanced rendering techniques in the field of computer graphics society. Since it takes a number of long operations, it cannot be easily implemented in real-time smartphone games. In this paper, we propose a subsurface scattering-based object rendering technique that is optimized for smartphone games. We employ our subsurface scattering method that is utilized for a real-time smartphone game. And an example game is designed to validate how the proposed method can be operated seamlessly in real time. Finally, we show the comparison results between bidirectional reflectance distribution function, bidirectional scattering distribution function and our proposed subsurface scattering method on a smartphone game. https://www.youtube.com/watch?v=x2eCJ6q_ky8

· Physiological parameters for skin rendering using spectrophotometer :

In this study, we apply skin data extracted from a spectrophotometer to a rendering model. We first divide the skin layers into the epidermis and dermis layers and then obtain the absorption and scattering coefficients for the wavelengths that match each skin layer. The absorption coefficient for each wavelength reflects the hemoglobin and melanin levels. Then, we store the percentage values of the hemoglobin and melanin levels as a table in a database and find from the database the hemoglobin and melanin levels closest to the skin color of a person, as  obtained with a spectrophotometer.

· A color scheme supporting technique based on hierarchical scene structure for exterior design of urban scenes in 3D :

In the research we propose a method for color scheme supporting system for exterior color design of urban scene in 3Dandconduct the user study for validations of color scheming. The realized simulator allows users to simulate harmonized coloring schemes for an urban color design in 3D with selection of a dominant color and sub-colors automatically. The technical approaches are composed of designing a color scheming table based on color guideline, extracting the face color form an image collected from a real scene, and conducting color scheming on the 3D scene. The method enhances efficiency with respect to reducing processing cost by improving the fact that color schemes are mostly dependent on experts and by utilizing the task for automatic color scheme in 3D as well. In addition, the 3D simulator provides interactivity for users in which it increase flexibility for manipulation of 3D simulated scenes by changing viewpoints rotating, zooming and navigating it as well. The experimental results and the user study are presented. https://www.youtube.com/watch?v=rhBphY3J1mI

· An automatic method for motion capture-based exaggeration of facial expressions with personality types :

Facial expressions have always attracted considerable attention as a form of non-verbal communication. In graphical applications such as movies, games and animations, people tend to be interested about exaggerated expressions rather than regular expressions since the exaggerated ones deliver clear emotions. In this paper, we propose an automatic method for exaggerations of facial expressions from motion captured data with a certain personality type. These exaggerations are created by using exaggeration mapping that transforms facial motions into exaggerated motions. As all individuals do not have identical personalities, a conceptual mapping of the individual’s personality type for exaggerating facial expressions needs to be considered. A popular method for classifying personality types is the Myers-Briggs Type Indicator (MBTI), which is employed to define the personality-type-based exaggeration mapping. Further, we have experimentally validated the exaggeration mapping and simulations of facial expressions. https://www.youtube.com/watch?v=A-WGAWXcN9g

· Personality Trait and Facial Expression Filter-Based Brain Computer Interface :

In this research, we present technical approaches that bridge the gap in research related to the use of a brain-computer interface for entertainment and facial expressions. Such facial expressions that reflect an individual’s personal trait can be used to better realize artificial facial expressions in gaming environment based on brain-computer interface. First, an emotion extraction filter is introduced in order to classify emotions on the basis of the users’ brain signals in real time. Next, a personality trait filter is defined to classify extrovert and introvert types, which manifest five traits: very extrovert, extrovert, medium, introvert, and very introvert. In addition, facial expressions derived from expression rates are obtained by an extrovert-introvert fuzzy model through its defuzzification process. Finally, we confirm this validation via an analysis of variance on the personality trait filter, k-fold cross validation on the emotion extraction filter, an accuracy analysis, a user study of facial synthesis, and a test case game. https://www.youtube.com/watch?v=nkdPTXE8PwE

· Expressive 3D Face for Mobile Devices :

Beyond a digital appliance, a mobile device now increases quality of life by providing ease of access to value-adding information. To further enhance the usage of a mobile device, media customization technology should be embedded into the mobile devices. Humanoid/anthropomorphic avatars are considered as a user-friendly technology to realize the media customization environment. This research formulates a computerized and expressive 3D face, which can be utilized as a mobile avatar. Input pictures are obtained by a built-in mobile camera and the associated customized 3D face is systematically generated in the mobile device. Six facial expressions are simulated by facial muscle motions embedded in the 3D mobile face. The generated 3D mobile face and expressions are exported to other compatible formats to increase usability. Finally, the system validation is conducted by a focus group study. https://youtu.be/Vvg46dEV2gA

· Emotional Intensity-based Facial Expression Cloning for Low Polygonal Applications :

In this paper, we present a simple and efficient emotional intensity-based expression cloning process for low polygonal-based applications, by generating a customized face, as well as by cloning facial expressions. We define intensity mappings to measure expression intensity. Once a source expression is determined by a set of suitable parameter values in a customized 3D face and its embedded muscles, expressions for any target face(s) can be easily cloned by using the same set of parameters. Through experimental study, including facial expression simulation and cloning with intensity mapping, our research reconfirms traditional psychological findings. Additionally, we discuss the method’s overall usability and how it allows us to automatically adjust a customized face with embedded facial muscles while mimicking the user’s facial configuration, expression, and intensity.
