Kenta Akita, Yuki Morimoto, Reiji Tsuruno, Hand‐drawn anime line drawing colorization of faces with texture details, Computer Animation & Virtual Worlds, https://doi.org/10.1002/cav.2198, vol.35, issue 1, 2023.07, [URL], Automatic or semi-automatic colorization can reduce the burden of illustrators in color illustration production, which is a research area with significant market demand. Texture details in eyes and hair influence the impression of character illustrations. Generally, these details are not expressed in line drawings. Many existing automatic or semi-automatic colorization methods do not target hand-drawn line drawings and it is difficult to paint texture details on such drawings. In this paper, we propose the semi-automatic colorization of character line drawings around faces with texture details. Our method uses a reference image as a color hint and transfers the textures of the reference image to a line drawing. To achieve this, our method uses semantic segmentation masks to match parts of the line drawing with the same parts of the reference image. We create two types of segmentation datasets to train a segmentation network that creates segmentation masks. We transfer texture details to a hand-drawn line drawing by mapping each part of the reference image to the corresponding part of the line drawing using segmentation masks. We show that our method is more effective for hand-drawn line drawings than existing methods using qualitative and quantitative evaluations..

Existing stylisation methods convert the colour of an object with a 1-dimensional texture for 3-dimensional computer graphics to reproduce a typical style used in illustrations and cel animations. However, they cannot express global illumination effects. We propose two individual methods to compute the global illumination and convert the shading to an arbitrary colour. The methods reproduce reflections in other objects with the converted colour. As a result, we can convert the colour of illumination effects that have not yet been reproduced, such as soft shadows and refractions..

Color illustrations are created by colorizing line drawings. Colorization task is tedious and time-consuming. Therefore, the automatic colorization system is expected. Most existing studies require a lot of user inputs as color hints for each region. Previous studies using reference images often fail to realize automatic colorization, especially for small areas, e.g., eye colors in the resulting image may differ from the reference image. However, eyes are important because these are noticeable in the characters' illustrations. In this paper, we propose a method to colorize line drawings of anime characters' face with accurate eye colors of an input color reference image. The proposed method estimates eye positions of line drawing and color reference image. Then round areas centered on these positions are color hints for our colorization network. Comparing with previous methods, our method can accurately colorize eyes of line drawings only with a color reference image..

Kenta Akita, Yuki Morimoto, Reiji Tsuruno, Deep-Eyes: Fully Automatic Anime Character Colorization with Painting of Details on Empty Pupils, Eurographics, accepted in EUROGRAPHICS & EUROVIS 2020 short paper, 2020.06, Many studies have recently applied deep learning to the automatic colorization of line drawings. 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..

11.	taihei meno, Reiji Tsuruno, Local Density Calibration for Position Based Fluids, International Journal of Asia Digital Art and Design, 21, 1, 41-48, 2017.10, [URL], This paper propose a improved PBF(position based fluid model)-based method for simulating realistic incompressible fluid flow. 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..
12.	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..

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..

15.	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..

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 contrast to previous methods in which the strokes are generated by per-pixel computation or using physically based simulation, our method is not only less computationally expensive but also capable of simulating various kinds of brushes. In addition, we introduce a fluid-dynamics-driven post-process and a Kubelca-Munk synthesis method to make the paint strokes appear more real. Our evaluation experiments show that our ethod can handle various media such as oil paints, water colors, charcoad, and pastels. We also obtained interesting results with lipsticks and fingers..

Variations in stress due to tibial anterior-posterior displacements were also introduced. All the results were compared and discussed with the previous studies, thereby verifying the validity and usefulness of our model..

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..

Kenta Akita, Yuki Morimoto, Reiji Tsuruno , Hand-Drawn Anime Line Drawing Colorization of Faces with Texture Details, Computer Graphics International 2023 (CGI2023), 2023.08, Automatic or semi-automatic colorization can reduce the burden of illustrators in color illustration production, which is a research area with significant market demand because the colorization of line drawings of character illustrations is time-consuming. Texture details in eyes and hair influence the impression of character illustrations. Generally, these details are not expressed in line drawings, but in colorization in color illustration production. Many existing automatic or semi-automatic colorization methods do not target hand-drawn line drawings and it is difficult to paint texture details on such drawings. In this paper, we propose the semi-automatic colorization of character line drawings around faces with texture details. Our method uses a reference image as a color hint and transfers the textures of the reference image to a line drawing. To achieve this, our method uses segmentation masks to match parts of the line drawing with the same parts of the reference image. We create two types of segmentation datasets to train a segmentation network that creates segmentation masks. We transfer texture details to a hand-drawn line drawing by mapping each part of the reference image to the corresponding part of the line drawing using segmentation masks. We show that our method is more effective for hand-drawn line drawings than existing methods using qualitative and quantitative evaluations..

5.	Kohei Doi, Yuki Morimoto, Reiji Tsuruno, Global Illumination-Aware Color Remapping with Fidelity for Texture Values, SIGGRAPH 2021, 2021.08, [URL], Our aim is to convert an object’s appearance to an arbitrary color considering the light scattering in the entire scene, which is often called the global illumination. Existing stylization methods convert the color of an object with a 1-dimensional texture for 3-dimensional computer graphics to reproduce a typical style used in illustrations and cel animations. However, they cannot express global illumination effects such as color bleedings and soft shadows. We propose a method to compute the global illumination and convert the shading to an arbitrary color. It consists of subpath tracing from the eye to the object, and radiance estimation on the object. The radiance is stored and used later to convert its color. The method reproduces reflections in other objects with the converted color. As a result, we can convert the color of illumination effects such as soft shadows and refractions..

Kenta Akita, Yuki Morimoto, Reiji Tsuruno, Fully automatic colorization for anime character considering accurate eye colors, ACM SIGGRAPH 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..

14.	目野泰平, 鶴野 玲治, 位置ベース流体シミュレーションのための局所密度補完モデル, 映像表現・芸術科学フォーラム, 2017.03, [URL], 精細な流体をリアルタイムで計算する方法として位置ベース流体シミュレーション手法がある。この手法では流体の非圧縮性を密度に関する制約として与え、制約を満たすように粒子の位置を直接移動する。この手法は高速で安定した計算が可能であるが、制約を満たすためには反復計算を行う必要があるためリアルタイムアプリケーションでは計算コストの面で問題となる。そこで本論文では、密度の制約を補完するために局所密度補完モデルを設定することで少ない反復計算回数でも非圧縮性を保つ手法を提案する。提案手法を用いることで、従来の手法よりも密度の安定化が可能であり、少ない計算コストで非圧縮性の実現が可能であることが確認された。 There is a position-based fluid simulation method as a method to calculate fine fluids in real time. In this method, incompressibility of the fluid is given as a constraint on density, and the particle position is directly moved so as to satisfy the constraint. Although this method is capable of high speed and stable calculation, it is necessary to perform iterative calculation to satisfy the constraint, which is a problem in terms of calculation cost in real time application. In this paper, we propose a method to maintain incompressibility even with small iterative calculation by setting regional density correction model to complement density constraint. By using the proposed method, it is confirmed that the density can be stabilized more than the conventional method, and incompressibility can be realized with less calculation cost..

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 in the depth direction, and it can express an appearance of the character between two viewpoints with considering depth information. Our method uses two cartoon-like illustrations and eye directions as inputs. These illustrations are consisted of contours and closed regions painted with uniform colors. Our method finds corresponding regions between two illustrations, and creates a 2.5D model by putting each matched region as a billboard in 3D space. These processes are semi-automatic. By completing regions that appear or vanish, our method can interpolate illustrations with occluded regions. .
