In this research, we propose a camera device that shoots the best shots of animals utilizing face recognition. We defined the best shots of animal as frontal shots. Our proposed camera device detects frontal shots utilizing image processing based on machine learning and save as images automatically. For not missing the best shots, camera device saves the sequence and then process sequence images to detect frontal face. When it detects frontal face, it saves that frame as a image file. From the result of evaluation experiment, our proposed camera device shoots the best shots easily.

I focused on fonts of "utterance telop" often used in television programs and the like, I investigated whether changes in the emotion received by the viewer from the speech in the video appear depending on the change in the font. I investigated the strength of sensitivity received from fonts, sounds, and video with a telop with respect to five kinds of "emotions" such as joy, sorrow, anger, fear, love. I made a conclusion by verifying whether the evaluation of the emotion of a video with a telop is influenced by the evaluation of telop rather than voice. As a result, we found that when we combine fonts and sounds with different emotions, the viewer feels stronger the emotion from the font than the voice.

Various methods can be considered for scene search, but in this paper we propose application of image recognition technology for movie scene search. After extracting an image per second from videos, we search a scene by using pre-trained models such as image captioning, object detection, and image classification to search a scene. The effectiveness of the recognition model was evaluated by calculating word2vec similarity between a query sentence and an output from pre-trained models and outputting ranking in ascending order.

We propose a method to automatically generate portrait drafts from face photographs. Prior
approaches are methods of combining finite number of parts and methods of applying image processing to generate
a portrait style image. However, the method of combining parts is mediocre, and image processing can not express
exaggeration peculiar to caricatures. In this research, we realized a method to automatically generate draft of
portrait by free curves.

Towards a safe sewer screening inspection, we have proposed a drifting network camera system.
In this paper, we report a method for detecting cracks from recorded videos in a sewer pipe, and the design of
the camera system for the screening inspection. The camera system designed using a light Raspberry Pi Zero
and able to float through a pipe in black water. A crack detection method using Gabor filters is proposed, and
results from an experiment in constructed mock-up from PVC pipes showed that all evaluation images were
detected. An experiment for the camera's utility in an actual environment resulted in water droplets being
reflected in the recorded video, clearly showing areas of improvement for video quality in practical use.

In origami design, a shape having curved surfaces is created by folding along curved lines. Computational
simulation is a way to preview the folded shape. However, the Origami Simulator, which is one of the most popular simulators,
only supports straight lines. In this paper, we aim to approximately realize curved folding using the Origami Simulator. First, the
curved lines are approximated by polylines. And then auxiliary lines are placed so that the curved surfaces are approximated by
polygons. Because the surfaces made with a sheet of paper are limited to ruled-surfaces, we placed the auxiliary lines to
approximate the rulings as much as possible. With our method, smooth surfaces approximated with triangles are generated with
the Origami Simulator.

The shape of the origami with curved foldings may be different from that of general folding paper and it is
difficult to grasp the shape when indirectly observing. Origami consisting of developable surfaces consists of straight lines
called rulings. In this research, we propose a system which can draw rulings interactively by a simple user interface for the
purpose of grasping the shape of curved origami easily. This makes it possible to draw rulings quickly on the 2D image.
Moreover, it can be applied to 3D shape reconstruction of origami with curved foldings using development.

Demands for video and character contents are increasing from market expansion due to mixed media, and the same is also true for crucial elements for stories creation. This research deals with clues which is one of the story production methods. In order to match authors′ intention, the cause and effect from clue was supported by writing the ploy in scenario production narrative. The hypothesis pattern and the trend of the numbers and placements of clues was investigated by analyzing the existing works. Based on this result, "data library" was developed, this allows authors to register discovered clues and simulated clues arrangement freely search for clues and a hypothesis writing support system which can register simulated placement by simulating placement. It was confirmed that "foreshadowing" can be produced by the system created as a result of the experiment.

The balance toy is traditional and popular toy, called YAJIROBEE in Japan. The common structure of this balance toy is composed of three parts: the central part with a thin rob (e.g., shape of human), the left and right parts which are connected with some heavier objects. Within this structure, the balance toy can maintain a good balance. The toy does not drop down even with shaking. The principle of this type of balance toy is that the position of center of mass should be below the vertical direction of the fulcrum. However, it is difficult to find the center of mass position in actual design for common users. If the shapes of the left and right parts are different, the design work is more difficult. The purpose of this study is to help common users design the balance toy easily. We propose the user interface for the design support of balance toy in which the user can adjust the balance of the toy.

When observing a binocular stereoscopic image, the observer sometimes evaluates that it felt unnatural. In this experiment, we
examined occlusion, which is considered to be one of the factors affecting stereoscopic vision. We measured the depth distances of the left
and right edges and the center of the target affected by half occlusion by the foreground. As a result of the experiment, under the condition
that the shielding amount is small, the left and right and the center tend to compress slightly from the theoretical value. Under conditions
with a large amount of shielding, the right and left and the center converge to a fixed value, but it stretched more than the theoretical value.
In the condition that the amount of shielding on the right side of the target is large, the left and the center are compressed compared with the
theoretical value and become equal to the right side.

Although blend-shape-rig is widely used for facial animation, there is less freedom of expression compared to computation time. On the other hand, skinning-rig is also popular, and used as a method for the complement of this drawback. However, artistic skill is required to construct the rigs. This paper proposes a rigging method to automatically convert a blend-shape-rig to the skinning-rig so that weight-map and control points are suitably and easily placed for facial animation creation.

Diminished Reality (DR), which removes real objects visually, is expected in various scenes. It is, however, difficult to remove an object in some scenes with textureless backgrounds. This paper, therefore, proposes a method to realize DR in textureless scenes. Missing backgrounds are filled by each divided background plane based on geometric information. The background is divided by boundaries of the background planes obtained by using Line Segment Detector (LSD), Hough transformation and the condition for concurrency of three straight lines. A removal object is tracked by feature point matching. 2D missing background completion fills in background plane regions obtained at each frame. In 3D background completion, missing backgrounds are filled in the first frame. Background regions obtained by projecting background boundaries are overlaid by the complemented backgrounds.

The purpose of this research is to propose a new way of practice for presentation through the usage of the VR technology. Nervousness during presentation may cause the person to concentrate excessively on the computer screen or the draft of the presentation. Hence, we are developing a new practice system by using the head mounted display device (HMD), in which the eye movement can be detected, and the user can practice under the virtual environment. In this research, in addition to this system, when the user is watching the material all the time, we used sound to grab the user's attention. Furthermore, when the user is watching the audience, the guidance point helps to evenly see the audience seats so the presenter does not focus on the same place all the time. Through these, we correct the gaze at the time of presentation.

Existing interactive projection mapping demos require users’ actions in front of the audience. This advantage is the interaction, nevertheless some of the audience refrained from participating. Therefore, we try to solve the problem by proposing a new projection mapping system. The proposed system uses a model of shrine which contains several sensors. When users shake the model or put cottons over it, the proposed system changes the projection images. Consequently, this system allows users of all ages who have negative mind for the existing interactive projection mapping, to increase their motivation for the participation.

We propose a technique for semantic segmentation of 3D human models. Existing techniques for general 3D objects solely rely on geometric information, which may suffer from distinguishing, e.g., skin and thin clothes. Our method thus exploits texture information as well. Specifically, our method first generates 2D data via projection from multiple viewpoints and feeds the data to neural networks to obtain likelihoods of semantic labels, which are then back-projected onto the human model. Note that likelihoods for some polygons are not available due to low-resolution 2D data and occlusion. We finally assign semantic labels for the entire mesh via graphcut.

variations from scratch is labor-intensive. In this study, we present a method for deforming an input facial model such that it
resembles a reference model. We apply non-rigid registration to the input model using a coarse graph structure that
approximates the model geometry. Specifically, we explicitly integrate the landmark points of characteristic shapes such as
eyes and nose into the coarse graph to retain the characteristic shapes during deformation. Consequently, we expect that the
proposed method can reduce designers’ burden of manual tasks substantially.

Considering that the interior decorates the space, it can be said that there is a close relationship between light and
space. Because of the color of light and the brightness, the natural light poured through the window is a big factor to change indoor atmosphere. Therefore, we focused on natural light in which how natural light varies in chronological order. In this
research, natural light is dispersed by a prism and the spectroscopic lights are projected on a canvas by passing through an
optical fiber. Thereby, we create an interior which utilizes both visible and invisible lights. “ Re-define” proposed in this
research gives the chance to the audience to redefine the phenomenon of light which we can not recognize in ordinary life.
Furthermore, “Re-define” have healing power because the fluctuation of natural light is used for the representation.

drawing system. It is constituted by a holographic pen device and a tabletop drawing canvas. Drawn 2D painting on the tabletop
drawing canvas is based on the algorithmic motion of holographic 3D graphics and user’s manipulation of holographic pen
device. The feature of our work is the existence of “uncertain dimension” which represents intersection dimension between 2D
and 3D. Users are able to make 2D painting utilizing intersection dimension. From the result of evaluation experience, our work

hands. A gold fish is spawned in a virtual pool when the hands make a ball-grabbing pose. The pose starts glowing, the hands
shoot rainbow particles systems , which makes us feel as if we perform a fantastic magic. We can also touch the spawned fish
by the virtual hands. We could say that this artwork is an aquarium in use of Leap motion in the virtual space.

This work is a media art work which designates the swordman as theme. It is not just reducing the traditional
martial arts motion, It aims to combine the imagination and technology to make experiencers feel interesting.
We did
the animation which Based on the ancient martial arts of China and Japan for studing the new efficient production
flow of 3DCG through Unreal engine ’s real time rendering function. Furthermore, according to Maslow's desire stage theory,
explain how to satisfy users as a 3DCG animator from desire of physiology to spirit step by step. I'd like to encourage
experienced people to feel like “ that has a good response, and I want to know the background behind that motion”.

We propose a public information VR content of SATREPS BHUTAN project for Bhutanese people. We planned to use the VR space as an exhibition site to report the results of the research project. This VR space is regarded as one form of “virtual museum” possibility, and in the space, materials related to the project are installed. In consideration of opportunities for many Bhutanese people to experience, it’s based on experiences of Oculus Go which is a portable stand-alone VR headset that is excellent in portability and is inexpensive. Our purpose is to increase disaster mitigation awareness among Bhutanese people through the project’s activities, so we have aimed at the space design suitable for the Bhutan's culture and simple operation. Players can freely experience the activities while moving in the VR space using the Oculus Go controller.

We developed a lifting training system using AR technology as an experiment for efficiently carrying out physical exercise training for improving sports. Kick the real foot against the virtual ball displayed on the transparent display of the AR device. Lifting is difficult to continue training due to gravity and variation in direction of repulsion. In this system, by using AR device, by controlling gravity and repulsion direction in virtual space, assist the beginner to continue training. Use the AR marker for estimating the position of the foot. Moreover, by adding tactile and auditory feedback when kicking the ball, it increases reality.

When searching for eyeglasses at optician's store, it is usual to try on eyeglass frames with lenses of plain glass. However, the impression may differ greatly between the face when wearing the eyeglass frame with lenses of plain glass and the face when wearing the eyeglass frame with prescription lenses. We propose a system that can display user’s faces when wearing the eyeglass frame with prescription lenses by using 3D computer graphics. Our system supports the task of selecting eyeglass frames with prescription lenses which suits to individual users.

We have developed a physical book interface that prints AR markers on pages as an interface for reading a book
in VR space. Our interface measures how bent the page of the book is from the positions of the AR markers. Based on the measured results, the page can be bent and displayed on the VR space. It was verified that evaluation experiment improved the reality of the page displayed on VR.

In recent years , the field of virtual reality has developed, and in order to make the experiences on the virtual
space realistic, various human-type devices are used. However, there are no studies that provide sensation like a ride on a floating object, which is often used in games and the like. In this study, we developed “OGRone (Ogloon)” which gives floating feeling according to the operation by the controller, considering the mechanism to support the effect of multi rotor for giving floating feeling to users.
