As the ability of electronic imaging devices, such as video cameras and liquid crystal display (LCD), continues to advance dramatically, 3-D imaging system has attracted a great deal of attention. It can be applied in many fields, such as the preservation of cultural heritage and traditional dancing, free viewpoint television, educational applications, and entertainment. In this talk, we will present the following two topics.


The first topic is the latest development of multi-view video coding (MVC) and our contributions in it. The successful application of multi-view videos in 3-D imaging systems needs technological advances in many fields. One of them is MVC. Many approaches have been studied for MVC, and the MPEG committee has been working on it since 2001. The basis of almost all studies is the standard MPEG coding with interview prediction. We have proposed to include the following two techniques to MVC. The first one is to use view interpolation technology, which synthesizes interpolated pictures and use them as reference pictures. The second one is to correct the luminance and chrominance of other views for interview prediction and view interpolation prediction (color correction). Since each camera has its own photoelectric variation, the correction is necessary and very effective.


In the second topic, we will introduce the Integral Photography (IP) camera, which can capture ray information of 3-D objects. We will also discuss multi-view video system and electronic holography system that use the IP camera. Holography is the technology to display ideal 3-D objects in space. Therefore, it has long been studied to use holography for 3-D display. Because the technology to manufacture fine pitch LCD is gradually maturing, electronic holography that uses LCD for displaying hologram has been studied extensively recently. Our group aims at realizing ultra-realistic communications, and tries to develop a real-time color holography system that captures 3-D objects and displays them in real time. Our developed system will be introduced in this talk.

Biography of Dr. Kenji Yamamoto


Kenji Yamamoto received his Ph.D. from Nagoya University, Japan in 2007. He is currently an expert researcher at Universal Media Research Center, National Institute of Information and Communications Technology (NICT), Japan. His research interests include 3-D image systems, such as multi-view video system and Integral Photography camera to capture the ray information of 3-D real objects, multi-view video coding to compress the captured data, depth estimation to synthesize new view image, and electronic holography to display 3-D objects.
