However, it is difficult to paint empty pupils using existing methods because the networks are trained with pupils that have edges, which are generated from color images using image processing. Most actual line drawings have empty pupils that artists must paint in. In this paper, we propose a novel network model that transfers the pupil details in a reference color image to input line drawings with empty pupils. We also propose a method for accurately and automatically coloring eyes. In this method, eye patches are extracted from a reference color image and automatically added to an input line drawing as color hints using our eye position estimation network..|

Published - Jul 28 2019, 2019.07, In this paper, we propose a method to colorize line drawings of anime characters' faces with colors from a reference image. Previous studies using reference images often fail to realize fully-automatic colorization, especially for small areas, e.g., eye colors in the resulting image may differ from the reference image. The proposed method accurately colorizes eyes in the input line drawing using automatically computed hints. The hints are round patches used to specify the positions and corresponding colors extracted from the eye areas of a reference image..

Our goal is to present simulation method of fluid phenomena as realistic as possible in realtime to many applications that require a high frame rate. Rapid fluid simulations are important for realizing real-time applications in computer graphics. Position based fluids (PBF) has been suggested as a practical method for real-time simulations of incompressible fluids. This method is based on the SPH(smoothed particle hydrodynamics) and realizes incompressibility by restricting the density. Furthermore, it reduces the calculation costs by allowing large time steps. However, because it iteratively calculates the density constraints, PBF is impractical for applications requiring high resolution and high frame rate. To increase the simulation speed of PBF, we replace the iterative density calculation by a density model. In the conventional method, iterating few density calculations compresses the simulated fluid. To resolve this problem, we consider the particle density and the direction of the fluid flow. We develop a computational model based on this hypothesis and verify its usefulness in simulations. The method suppresses the fluid compression even in a non-iterative model. We conclude that the proposed computational model effectively maintains a constant density in PBF..|
|6.||Taihei Meno, Reiji Tsuruno, Local Pressure Correction Model for Position Based Fluids, Asia Digital Art and Design, 4A-6, 2016.11, Speed of fluid simulation calculations is an important factor for realizing real-time applications in computer graphics.
Position based fluids (PBF), which is an incompressible fluid simulation method, has been suggested as a practical
method for real-time simulation. Using this method, it is possible to take large time steps; therefore, the cost of
calculation can be reduced. However, method is not practical for applications that require high resolution and frame rate
because it is necessary to iteratively calculate the density constraints. In this study, we developed a pressure model that
replaces the iterative density calculation in PBF to realize faster simulation. First, we hypothesized that problems with
incompressibility caused by a small number of iterations can be solved by considering the influence of pressure. Second,
we used an alternative pressure model that uses this hypothesis and verified it using simulation. The pressure
interpolation model uses the function relating to the distance and the density. The results confirm that compression of the
fluid can be suppressed even with a small number of iterations. Finally, by considering the influence of pressure in PBF, it
was possible to substitute the proposed model for iterative calculation of the density constraints..
|7.||Maki Kitamura, Reiji Tsuruno, 2.5D Modeling from Illustrations of Different Views, international Journal of Asia Digital Art and Design, 8, 4, 74-79, 2015.01, When artists design characters, they draw illustrations viewed from the front, side or slant views. In this paper, we create a 2.5D model using such illustrations. A 2.5D model is a model that is created by arranging deformable billboards along the depth direction, and it can express appearance of the character between two viewpoints with considering depth information.
Our method uses two cartoon-like illustrations and the corresponding eye directions as inputs. These illustrations are composed of contours and closed regions painted with uniform colors. Given closed regions in illustrations, our method finds corresponding closed regions between two illustrations based on an improved similarity function, which yields better matching than a previous method. After obtaining correspondences of closed regions, our method creates a 2.5D model by transforming each pair of matched regions as a 3D billboard whose position can be estimated based on the correspondence. These processes are semi-automatic. The user then assigns feature points manually along the corresponding contours of matched regions so that the contours can be interpolated naturally. Finally, by completing regions that appear or vanish with user strokes, our method can interpolate illustrations with occluded regions. We demonstrate that our method can create 2.5D models with various illustrations..

To achieve the desired motion, we define additional forces using control particles that employ the Navier–Stokes quation. Control particles are generated from a fluid area chosen by the user, and their behavior is sequentially determined using a shape-matching method referring to the target shape. Our method enables interactive simulation of fluid animation that is gradually deformed to the target shape following physical laws..|
|9.||Junmin Park, Reiji Tsuruno, A Color Palette based Interface for Biological Iridescences Rendering, Asia Digital Art and Design Association, 18, 1, 4-11, 2014.07, [URL], Iridescent colors can be observed on many biological objects including morpho butterflies and Japanese jewel beetles. While ordinary colors are induced by pigments in surface, the iridescent colors are caused by interference of light due to microstructure covering the objects. To render iridescences in computer graphics, users need to consider a lot of physical parameters such as index of refraction or film layer thickness. However, in such input systems, users are difficult to predict rendering results since iridescence is affected by combination of those many physical factors. In this paper, we propose a color palette based interface for biological iridescences rendering, with which users can pass information for rendering iri-descences to system by picking colors instead of by inputting physical data of surface. Incident angle dependency of re-flectance spectrum is studied to achieve physically sound simulation and color picking user interface. We also evaluated our system through rendering results and user study in the latter half of this article..|

In general, 2D computer graphics are most commonly used to depict 2D structures. However, many computer games often depict three-dimensional (3D) structures using 2D computer graphics. We dene such an expression as an overhead view. Although an overhead view has no 3D structure, we can perceive an ambiguous 3D structure from it. In this study, we dene shape perception rules from the overhead view and propose a novel modeling system using it. We also propose a tile-based interface as a prototype system that can create a 3D shape from an overhead view and can seamlessly convert an overhead view into a 3D view. In addition, we conduct a psychological experiment by means of which we conrmed our system is highly intuitive and can quickly create 3D models..|

In our method, we preserve fluid sheets by filling the breaking sheets with particle splitting in the thin regions, and by collapsing them in the deep water. To identify the critically thin parts, we compute the anisotropy of the particle neighborhoods, and use this information as a resampling criterion to reconstruct thin liquid surfaces. Unlike previous approaches, our method does not suffer from diffusive surfaces or complex re-meshing operations, and robustly handles topology changes with the use of a meshless representation. We extend the underlying FLIP model with an anisotropic position correction to improve the particle spacing, and adaptive sampling to efficiently perform simulations of larger volumes. Due to the Lagrangian nature of our method, it can be easily implemented and efficiently parallelized. Our results show that our method can produce visually complex liquid animations with thin structures and vivid motions..|

, 2011.08, We present a new particle-based method that explicitly preserves thin fluid sheets for animating liquids. Our primary contribution is a meshless particle-based framework that splits at thin points and collapses at dense points to prevent the breakup of liquid. In contrast to existing surface tracking methods, the proposed framework does not suffer from numerical diffusion or tangles, and robustly handles topology changes by the meshless representation. As the underlying fluid model, we use Fluid-Implicit-Particle (FLIP) with weak spring forces to generate smooth particle-based liquid animation that maintains an even spatial particle distribution in the presence of eddying or inertial motions. The thin features are detected by examining stretches of distributions of neighboring particles by performing Principle Component Analysis (PCA), which is used to reconstruct thin surfaces with anisotropic kernels. Our algorithm is intuitively implemented, easy to parallelize and capable of producing visually complex thin liquid animations..

In the BC migration, there are two kinds of atom migrations. One is that in which a BC atom pushes its neighboring atom to a BC site. This is the typical migration by the interstitialcy mechanism. The other is that in which a BC atom rotates about its neighboring atom and becomes the BC atom again. This is a feature of the BC migration. (2) The BC and SP migrations are applied to P diffusion in Si. Assuming there is no interaction between P and Si, the distance and probability for each step of the migration are obtained and applied to Si self-diffusion. Because they are not constant, the definition of the correlation factor for the self-diffusion is different from the usual one..|

Such assumption was made that the ACL can be idealized as being composed of a homogeneous matrix in which two non-interacting families of densely distributed extensible fibers are embedded. A non-linear stress-strain characteristic exhibited by multiple collagen fibers was represented by the tri-liner curve. Then a constitutive equation for the ACL composite was formulated. Using the finite element method, a 3-D finite deformation and stress distribution of the ACL as a function of knee flexion were introduced through simulation and their graphic representation was made..

Furthermore it is impossible to directly measure in-situ, non-uniform distribution of biaxial strain over the entire surface of the intra-articular ligaments. We employed an alternative approach; Instead of using an actual knee and ACL, a knee motion simulator and a pseudo ligament were prepared. The pseudo ligament was manipulated so as to simulate the deformation and stress the actual ACL undergoes during knee flexion. Two hundred and ten points drawn on the pseudo ligament at regular intervals, were measured by the stereo-photogrammetric method, and components of the Green strain tensor were computed. Next, using the finite element method, in which the ligament was treated as an incompressive hyperelastic membrane, the finite deformation of the ligament was theoretically analyzed. The results demonstrated that strain distribution varied, even along the fiber run, and large strain gradients were observed in the regions near the insertions. Futher, the following values were obtained as a function of knee flexion: three-dimensional change in shape, resultant pull force on the tibial insertion, and change of strain pattern by anterior-posterior displacement of the tibia..|
