2013年5月23日，日本名古屋大学的谷本正幸（Masayuki Tanimoto）教授访问模式识别与机器智能实验室，并向自动化学院的师生做了题为“FTV (Free-viewpoint Television)”的学术报告。
FTV (Free-viewpoint Television)
Television realized a human dream of seeing a distant world without actually going there. However, it allows the users to see only a single view of a 3D scene they want to see. Furthermore, the viewpoint can’t be changed by the users. Stereoscopic 3DTV also has the same limitation although it transmits 2 views for right and left eyes and gives us 3D sensation. FTV (Free-viewpoint Television) is an innovative visual media that breaks down this limitation of the current visual media and allows the users to see a 3D scene by freely changing the viewpoint. FTV is the ultimate 3DTV and ranked as the top of visual media since it transmits infinite number of views. FTV is not a conventional pixel-based system but a ray-based system. FTV has been realized by developing new types of ray capture, processing and display technologies. An all-around ray-reproducing 3DTV was also realized by using these technologies. The international standardization of FTV has been conducted at MPEG. The first phase of FTV is MVC (Multi-view Video Coding) and the second phase is 3DV (3D Video). The principle, technologies and standardization of FTV are overviewed.
Masayuki Tanimoto received the B.E., M.E., and Dr.E. degrees in electronic engineering from the University of Tokyo in 1970, 1972, and 1976, respectively. He joined Nagoya University in 1976. He was a Professor at Graduate School of Engineering, Nagoya University from 1991 to 2012. In 2012, he retired from Nagoya University and became an Emeritus Professor. Currently, he is a Senior Research Fellow at Nagoya Industrial Science Research Institute.
His research interests include image coding, image processing and 3D imaging and ITS. He developed TAT (Time-Axis Transform) system for HDTV compression. TAT system became one of the two candidates for HDTV satellite broadcast system in Japan. He also developed FTV (Free-viewpoint Television). FTV is the ultimate 3DTV that allows the users to see a 3D scene by freely changing the viewpoint. Since 2001, he has been promoting the standardization of FTV at MPEG.
He was the president of the Institute of Image Information and Television Engineers (ITE). He is IEEE Life Fellow and Fellow of the ITE and IEICE (Institute of Electronics, Information, and Communication Engineers). He received the ITE Distinguished Achievement and Contributions Award, the IEICE Achievement Award, and the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science, and Technology.
