Gait is one of biological information which indicates how to walk. It is able to acquire gait from a distance and any views. It is, however difficult to identify a person with belongings. The purpose of this article is, therefore, to propose an effective identification method when the subject has a bag. First, GEI(Gait Energy Image) is generated with head position adjustment. Then, gradient of GEI for head, both arms and legs regions are obtained. Finally, features from each region except for the hand region with a bag and the bag itself in the leg region. The proposed method gets 95.0% identification ratio for back view gait with belongings.

The recent increase in the number of patients with lifestyle diseases has become a global problem. One of the primary is stress. As a method to reduce accumulated stress, activities such as exercise and contact with nature should be performed. However, these are time consuming, and difficult for people who do not have much time to spare. This research proposes a system that reduces stress easily and rapidly. As a system structure, we first record the facial expressions when presenting some images and presenting natural images with relaxing effect. Secondly, by determining the order and time for displaying images so as to match the facial expression change at relaxation, the same facial expression change as at relaxation is induced. As a result of examining the amount of stress using the pulse, it was revealed that relaxation effect was higher by this method in 80% of subjects.

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.

Fine particles are defined as a mass of solid particles whose radii are smaller than 200µm. In particular, finer particles with radius smaller than 100µm are called adhesive fine particles, because those particles tend to adhere to one another. Adhesive fine particles are ubiquitous in our daily life; flour and powdered medicine are good examples of those. In this study, we attempted to model the behavior of adhesive fine-particles, which had never been reported in the literature. First, we adopted a representative particle model to narrow the dynamic range of the computation, though the existing model itself does not take inner frictions into account, which motivated us to allow each of the particles to hold its yield criteria. Our method successfully reduced the computational complexity and realized a feasible simulation of characteristic cracks on the surface of adhesive fine particles.

We propose a method for measuring reflectance with a simple setup based on bivariate BRDF, a simplified version of BRDF. Most measurement methods require large systems for illuminating target objects from various lighting directions. Our method reduces the number of lights by finding light directions suited for a target shape via combinatorial optimization. We also reduce artifacts occurring when recording reflectance, which stem from the narrow representation domain of bivariate BRDF. We further reduce the impact of clustering errors in case of objects containing multiple materials. In summary, we demonstrate our method can capture reflectance more accurately with less lights.

We propose reproduction of scattering property by mixing different optically liquids physically. We find a relationship between the mixture ratio and scattering property of mixed liquid by observation. According to the relationship, we attempt to estimate optimal mixture ratio for reproduction of given translucent objects. Finally, we evaluate the accuracy of the estimation and reproduced some translucent objects in experiments.

Controlling a behavior of Non-Player-Character (NPC) which appears in digital game has several tasks. In this research, by focus on ``communication" ``emotion" and ``mechanism of cooperation", we constructed ``NPC's decision-making model" which decides behavior based on the character assumed by the game designer. We constructed the model inspired by Hume's moral sentiment. We created a test case to confirm behavior, for 3D battle game, and confirmed the result. As a result, NPC's decision was made normally and no deadlock was confirmed. As future tasks, it needs to add test cases and add intuitively operable interfaces for game designers.

Hands are particularly eye-catching regions from the first-person point of view as well as from the second and third, because they most frequently interact with surrounding objects. General CG models consist of surface mesh and bones, whereas there exist organs such as tendons and muscles inside real hands. Their motion such as muscular contraction effects a change in the appearance of hands’ surface, and thereby moves characters more dynamically, which cannot be realized only with weighted mesh’s vertices for each bone. In this work, we propose a method to represent internal structures of hands as scalar functions and to implicitly model the hands’ surface based on the motion of internal structures.

The teaching material was developed by programming language Java; however, the environment of Java has changed and it has become impossible to operate on the recent browsers. We report that UEI Research is developing the teaching material that includes the same contents with JavaScript so that learners can study CG on web browsers. Because this material is operated with popular mobile terminals, learners can experience CG basic techniques not only in classrooms, but also by self-study. The content consists of more than 50 CG basic techniques such as Z buffer method, ray tracing method, and image processing. The goal is to educate learners by this system and to disseminate knowledge of CG widely.

When the head mounted display is attached, it interferes with the majority of the face of the user, so it is difficult to visually recognize the facial expression of the user. In this research, when the user's facial expression is photographed in advance and displayed with liquid crystal on the front of the HMD, the user's facial expression as seen from the outside when the user's facial expressions are ambiguous is not clear. Therefore, we propose visualization of facial expressions using 8 × 8 dot images as a visualization method of more effective facial expressions. Due to the dot image, subtle expressions are not displayed than the actual image, so it seems that you can more clearly understand the user's expression.

Makuranosoushi is made up of about 300 chapters, there is a characteristic that you can start reading from anywhere. While conventional media such as books have a linear structure, we develop a system with a structure that allows you to freely read from anywhere you start reading. So, present to readers with expressions using 3DCG. Utilizing our system, readers can read Makuranosoushi as they like without flipping pages, and understand the background of each chapter from many sides. This approach is one of the effective methods to preserve literary works.

The recent spread of head-mounted displays and hand-tracking controllers allows to create Virtual Reality (VR) games with virtual grasping. To realize a realistic sense of firm grasping, such VR games require many grasp animations that make fingertips precisely touch the target objects. However, each and every grasp animation is only adequate for an individual object, and cannot be reused. This article presents an animation technique taking into account affordance information to reduce the production cost. The proposed method enables to grasp target objects in a variety of postures, by interpolating grasp poses acquired from affordance information. For that reason, this method is applicable to the currently prevalent hand tracking controllers which cannot sufficiently capture the user’s finger movements.

Camera positions and attitudes are necessary to synthesize and compose images of virtual objects in AR applications. Although markerless AR techniques using local sensors such as a GPS and a geomagnetic sensor are useful without specific preparations in the AR locations, accuracies in directional sensing limit their applications. In this study, we utilize both global sensors, such as GPS and Kinect, and local sensors, such as acceleration sensors and gyroscopes. By matching the two motion paths of a given device obtained by the both global and local sensors, we can estimate the camera attitude. Simulation experiments demonstrated positive results.

When creating a computer-generated hologram，we convert 3D objects from polygons to sets of points． Conventionally，since the point light source data was generated from the scene information，it was necessary to recreate the scene with the 3DCG software when changing the arrangement of the object．Software developed in this research makes it easy to correct scenes by loading objects and allowing scenes to be constructed within point cloud generation software．
