- Web サイトをはじめとする様々な情報をテレビ番組的なCG アニメーションに自動変換する研究開発を進めている．今回，その試みの一つとして，「２ちゃんねる掲示板」からコンピュータ・グラフィックス(CG) アニメーションを自動生成するアプリケーションを開発した．基本的な方法は，実際のテレビ番組映像を分析し，そこで使われている制作ノウハウを抽出して，これをルール化および数値化し，ソフトウェアに実装することで，テレビ番組を真似たCG アニメーションを得るというものである．今回，実際に放送された1 時間分の討論番組映像のカメラスイッチングを解析しアルゴリズム化した．本論文では，このプロセスの詳細を説明し，この方法により作成した実際のアプリケーションについて述べる．また，得られたCG アニメーションについて評価実験を行い，本手法の有効性と今後の課題を明らかにしたので，これについて述べる．

Implementation of T2V : Text-To-Visio on Game Engine UNITY
- 2013
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- We have been developing T2V (Text-To-Vision) technology which enables to produce CG animation from given script. We have developed the application called 'T2V Player' and have been distributed it as freeware for years. The application works on Windows PC to produce TV-program-like animation from user input text using real-time CG and voice synthesizing technique, etc. In this paper, we introduce the prototype of 'T2V on UNITY' which has been developed from scratch on the UNITY game engine. We succeeded to enhance its function owing to the UNITY, such as multi-platform, availability of CG character data circulated on UNITY community, capability of applying T2V method to game development and more.

System Development Kit of T2V in the Unity : T2V Engine Capable of Converting Script to CG Animation in the Unity Game Engine
- 2014
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- T2V (Text-To-Vision) is the technology which enables to generate TV-program-like CG animation by computer from a given script. In this time, we have developed a system development kit (SDK) which makes it possible for developers to create various interactive applications in the Unity with utilizing the T2V technology. We first explain the SDK and its usage. Secondly, we introduce two applications made using SDK: 1) Automatic generation of talk show from a bulletin board in the Internet, 2) Interactive quiz application with multi-story structure.

TV News Show Broadcast Generated Automatically from Data on the Internet
- 2012
-
Ingår i: Proceedings of 2012 ITE Annual Conference. ; , s. 1-2
-
Konferensbidrag (refereegranskat)abstract
- We propose an automatic news broadcasting system, which generates full-CG animated news-shows fromoriginal text formats from the Internet. This paper introduces the overall system and provides a feasibility test and workingmodel of the news show application generated from a HTML Internet news site. We also describe the future collaboration work.

Virtual Museum on 4K Ultra-high Resolution Real-time CG System
- 2013
-
Ingår i: Proceedings of Virtual Reality Technical Seminar.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- We have researched and developed a 'Virtual Museum' in an extreme high-definition real-time computer graphics system with a resolution of 4K and 8K (Super Hi-Vision). We have first developed a functioning test system, which exhibits Japanese artifacts 'Ukiyoe and pannel' in 4K resolution. In our system, the artifacts have been digitized in ultra high-resolution then positioned in a high-quality modeled exhibition space. A user can walkthrough in the exhibition space enabling to view the artifacts in a distance and also to get closer to observe its detailed surface seamlessly. With this method, we have successfully enhanced both sense of being there and sense of realness. In this paper, we first survey several virtual museums in practical use, then explain the detail of our system and introduce experiment results with discussion in comparison with the existing virtual museums.

ラップスクリプト : テキストを書いて音声合成とCGアニメのラップが作れる
- 2017
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- We have made an application to make rap music with CG animation by writing out a simple script. Aquestalk and TVML are used for synthesized voice and real-time CG generation, respectively. A user can enjoy making rap music video easily by writing speech texts and character movements along with music beat in the script.

Color Similarity Metric Based on Categorical Color Perception
- 2013
-
Ingår i: ITE journal. - 1342-6893. ; 67:3, s. 116-119
-
Tidskriftsartikel (refereegranskat)abstract
- The calculation of color difference is one of the most basic techniques in image processing fields. For example, color clustering and edge detection are the first steps of most image processes and we compute them by using a color difference formula. Although the CIELAB color difference formula is a commonly used one, the results obtained with it are not in accordance with human feelings when the color difference becomes large. In this paper, we have performed psychophysical experiments on color similarity between colors that have large color differences. We have then analyzed the results and found that the similarity is strongly restricted by the basic color categories. In accordance with this result, we propose a new color similarity metric based on the CIEDE2000 color difference formula and categorical color perception.

How to Evaluate Learning Outcomes of Stereoscopic 3D Computer Graphics by Scene Rendering
- 2013
-
Ingår i: ITE Technical Report. - : ITE. ; , s. 21-24
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- Use of stereoscopic 3DCG (S3DCG) is increasing in movies, games and animations. However, a method for objectively evaluating production capability has not been established. If possible to measure the production capability on basis of certain criteria, unified evaluation can be useful at school. In addition, it is useful to human resource development and adoption of enterprise. Therefore, the experiment conducted practical tests using 3DCG software to making a scene of S3DCG. The practical tests were carried out before and after subjects learning. As a result, it was able to measure improvement of subject's capability after learning, and the difference in capability between subjects. In this paper, we will report on the experimental method and results．
