Abstract [en]

TVML (TV program Making Language) is a technology capable of obtaining TV (television)-programme-like Computer Graphics (CG) animation by writing text script. We have originally developed TVML and have been studying generative contents with the aid of TVML. This time, we have created an application that automatically converts blog posts into CG animations with TV news show format. The process is: 1) to fetch HTML of the blog posts and perform Web scraping and natural language processing to obtain summarized speech texts, 2) to automatically give a show format obtained from the analysis of professional TV programme to get TVML script, 3) to apply the CG character and artworks etc. that fit the blog content to obtain the final CG animation. In the demo session, we will explain the method and will demonstrate the working application on a PC connected to the Internet showing CG animations actually created on site.

Abstract [ja]

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.

Abstract [en]

We have developed a blog system with Wordpress which has a capability of automatically converting its blog entries into CG animations. By embedding necessary functions in Wordpress' s theme, a user can select this theme and construct a blog where readers can watch CG animation instead of reading the blog entry. The CG animation is created by TVML (TV program Making Language) technology which enables to make a TV-program-like animation with CG characters with synthesized voices, image data display, sound data playback, superimposing and so on. Not only to contribute to the Wordpress community, in particular, expected as an auxiliary function of the blog service, but also this could work as a production tool for creating various types of CG animations rather than blogging assistance.

Abstract [en]

We have made an application to make rap music video with CG animation by writing out a simple script. Aquestalk and TVML (TV program Making Language) 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 the music beat in the script.

Abstract [en]

We have developed an application to produce Computer Graphics (CG) animations in TV talk show formatsautomatically from the Internet forum. First, an actual broadcasted talk show is analyzed to obtain data in regardsto camera changes, lighting, studio set up, etc. The result of the analysis is then implemented into the applicationand a CG animation is created using the TV program Making Language (TVML). The application works in theUnity game engine with CG characters speaking with computer generated voices. We have successfully created aCG generated TV talk show which allows users to "watch" the TV show format generated from the text informationcoming from the forum on the Internet.

Abstract [en]

We have developed a Virtual Museum with real-time 3DCG capable of exhibiting arbitrary planar artifacts such as paintings which have been specified by a user. The pictures are collected from the Internet sites such as Wikimedia Commons by giving bookmarks by the user. The artifact images are displayed in its life size automatically aligned on the wall of the museum with picture frames and generated captions. This process is done based on metadata extracted using a technique called Web scraping to extract necessary information from the target Web sites. The museum space is realistically modeled with high resolution and sophisticated illumination where the user can walk through in the space. The system enables the users to create their own personalized museums with their favorite pictures exhibited in the realistic way.

Abstract [en]

We have been developing a new type of Virtual Museum which enables users to participate in the space with both active and passive modes of operation. In the "active mode", the new virtual museum provides a user walkthrough using the realistic 3DCG-modeled museum space and artifacts in the space. And in the "passive mode", the system adds desired visual and audio effects such as camerawork, superimposed text, synthesized voice narration, post production processes, background music and so on to give users a TV commentary type of CG animation. Users can easily transition back and forth between the two modes of doing walkthrough in the space actively and watching the video content passively. This paper describes the details of the system design and the implementation followed by a discussion on the functioning prototype.

Abstract [en]

This paper describes the implementation of the Text-Generated TV that we had previously proposed. It uses textscript to circulate on the network and a user can watch TV program videos with a specially designed playerconverting the scripts to computer graphics animations. We have developed the Player prototype in Unity gameengine for viewers and deployed the Text-Generated TV broadcast station on the server where actual contentsare ready to view. The software is downloadable and a user can actually watch TV with the player on a PC.

Abstract [en]

We have been studying and developing the systemwhich enables to generate Computer Graphics Animation (CGA)automatically by processing HTML data of Web site. In thispaper, we propose an open framework to facilitate this. Theframework is functioning all at a server side, obtaining theHTML, converting it to a script describing the CGA story andupdating the script. And at a client side, a user accesses the scripton the server to visualize it by using real-time CG character withsynthesized voice, camera work, superimposing, sound fileplayback etc. We have constructed the framework on the serverand deployed the substantial engines to convert Web sites toCGAs. This paper describes the detail of the framework and alsoshows some example projects providing automatically generatedNews show, Talk show and personal Blog visualization.
