Research Abstract

The aim of this research is to revolutionize communication systems from the 2-D image communication " used widely nowadays to the "Integrated 3-D Visual Communication" that should allow us to share the 3-D space itself. Especially, we pointed out the large number of technical problems for this dream systematically and gave basic investigations of each topic.
1.Discussion on the Future of the Integrated 3-D Visual Communication and Study on Technical Difficulties in 3-D Image Coding
We gathered and investigated the information from both Japan and foreign countries related to the present 3-D imaging technologies and the future image communication systems. We also categorized several research topics in 3-D image coding.
2.Theoretical Systematization of the Ray-Based Representation Method for 3-D Spatial Data
Systematically, we clarified the relationship between conventional "Image" processing techniques and processing techniques for "light ray data". Furthermore, we proposed some methods for … More mutual conversion between light ray data and several visual data aiming to realize the comprehensive visual communication systems.
3.Investigation on Efficient Methods for Sampling 3-D Spatial Data
A system that can take (capture) samples of light ray data was constructed. Moreover, we examined how to sample the data efficiently by introducing a method for measuring 3-D shape. We also constructed a system that captures a set of orthogonal views and studied its applicability to the Integrated 3-D Visual Communication, experimentally.
4.Study on Statistical Approach to Compressing the Large Amount of Light Ray Data
We studied how the 2-D image compression methods such as motion compensation and discrete cosine transformation are effective for data compression of light rays. According to this study, a segmentation method for representing light ray data in a structural way was examined.
5.Proposal form Human Interface Techniques in Immersive Projection Systems
We proposed and implemented the concept of Reflection-Based Interface and Virtual Light Interaction as human interface techniques for merging the real and virtual worlds seamlessly. Less
