Report on the 3DC Conference 2009 in NAGOYA
(Venue: Nagoya University, Venture Business Laboratory "Venture Hall" in Higashiyama Campus)
June 12, 2009
Campus of Nagoya University (Higashiyama Region)
The 3DC Conference which is our annual "open event" was organized jointly by the Information Technology Center of Nagoya University on June 12 at Higashiyama Campus of Nagoya University after four years' interval since the event was last organized in Nagoya.
The theme was "Video, sensors, networks and contents".
For Part 1, we invited lecturers who have been active in the field of video, analysis of skill succession and development of displays for posting including professors of Nagoya University and others who have been conducting research in these fields.
In Part 2, an intermediate report of experiments for distribution of posted 3D videos which have been conducted by t the Broadcasting and Communication Contents Research Working Group (WG) of the 3D Consortium since March 2009 was made, because it was decided to extend the period for the experiments to the end of December 2009.
After the intermediate report, a panel discussion was conducted under the theme, "Prospects for experiments of distribution". A panel discussion was held with participation by representatives from the broadcasting industry, researchers on communication/mobile devices, and system integrators and consumers, which led to an active discussion which, ended successfully.
During the reception organized at the same venue after the conference, a presentation of 3D video by using red and blue glasses and projectors was made. Demonstrations and exhibitions were also held there.
There were 33 companies at the conference for a total of 65 people attending.

[Part 1] "Lectures"
"Calibration for image compensation required for 100-lens systems and also for handy Web stereo cameras"

Assistant Prof. Department of Scientific and Engineering Simulation, Nagoya Institute of Technology
Dr. Norishige Fukushima
>>Outline of lecture
For natural stereoscopic vision, shooting simply by two cameras in parallel is not sufficient; parallelization of stereoscopic video is required. There are two kinds of techniques for such processing for parallelization; one of them requires prior adjustment including camera calibration and the other does not require such prior information. In this presentation, explanations were made about the requirements for making the shooting of 3D video easier and more familiar by using three examples achieved by two stereo cameras, 25 cameras aligned in parallel and 100 cameras aligned in-line for each of these two techniques.
"Specified Ubiquitous District in Nagoya - Research and development of 'New one-segment terminals' in the 'era of integration of broadcasts and communications'"

General Manager, IT Department, Media Development Division, CHUKYO TV. Broadcasting Co., Ltd.
Mr. Noriyasu Suzuki
>>Outline of lecture
Since one-segment receivers which are now installed on more than 80% of mobile phones with accumulated shipment of 55 million units can accept services which integrate broadcasts and communications, their further utilization as "information terminals" in a ubiquitous society has come under the spotlight. Concerning the public offering of "Specified Ubiquitous Districts" by the Ministry of Internal Affairs and Communications two years ago, the "Nagoya Specified Ubiquitous District Consortium" was established by five commercial TV stations in Nagoya, Nagoya University, Nagoya Institute of Technology, Aichi Prefecture, Nagoya City and other relevant corporations and the Consortium was entrusted with a "project for development and experiments of new one-segment terminals". Functionalities of a "browser which can be commonly used for broadcasts and communications", "linkage with e-money", "utilization of location information" and "DRM" were introduced as a result this last year in the first year of its establishment.
"Understanding of driving activities and production of contents by using multi-cameras and multi-sensors for vehicle installation"

Prof. Department of Media Science, Graduate School of Information Science, Nagoya University
Dr. Kazuya Takeda
>>Outline of lecture
Compilation of a database of driving activities started as research on mathematical models regarding human activities. Assuming that activities are the aggregation of environmental information (input), driving operations (output) and psychological state (inner status), we thought that a model of human activities could be created by exhaustively measuring such information and by using statistical signal processing. However, by looking at the huge database, we noticed that, in fact, we receive various information only by looking at "what others do". So we came to an idea; "Can driving records be contents?"
"Retinal imaging display in the shape of glasses"

Brother Industries, Ltd.
Mr. Tomohiro Sato
>>Outline of lecture
Retinal imaging display (RID) is a video projection techniques that uses effects of persistence of vision which is created by irradiating light with safe brightness on our retina and by moving the light at a high speed. Images projected on our retina are recognized by our "vision" and we feel as if the images actually exist in front of us. By using these technologies, Brother Industries, Ltd. has been advancing the development of small displays in the shape of glasses that we can wear on our face. Characteristics of this small, glasses' shape display and possible scenes for its utilization were introduced.
"Research on usage of multi-view video for production skill succession"

Prof. Information Planning Office, Information and Communications Headquarters, Graduate School of Information Science, Nagoya University
Dr. Kenji Mase
>>Outline of lecture
Free viewpoint TV technologies by recording actions and visual scenes with multi-lens cameras which enable viewing images from any viewpoint have been attracting attention as a promising method for viewing sports and performances. This presentation proposed methods for presenting video by using the peg scope navigation method featuring objects of shooting focusing on the fact that the degree of freedom in the viewing space for free viewpoint TVs is naturally restricted by the objects which attract the interest of viewers. Taking production of multiview images for skills training and skills succession as an example, designs utilizing sensor data were introduced.
