2001.1- "Ubiquitous stereo vision for human sensing"
To realize an easy and touch-less human interface in a room, we proposed a Ubiquitous Stereo Vision system, which is an extension of the single learning stereo vision system. In this research, our aim was not to reconstruct exact 3D structures or to track objects by active cameras. Instead, by using stereo cameras placed ubiquitously, the system decides on multi-interest regions by using the depth information from each camera, recognizes multi-regions in parallel and integrates all information. Our objective was to create an easy interface and describe all the actions of users. For this purpose, we investigated a method of learning multi-images from multi-cameras in Gigabit Ethernets.

"Utilization of stereo disparity and optical flow information for human interaction"
We researched more flexible human interaction by utilizing both stereo disparity and optical flow. To use two data in real time, we utilized multi-resolution images on the Pyramid Vision system.

"Automatic acquisition of hierarchical mathematical morphology procedures by genetic algorithms"
We researched a method to obtain an image processing procedure by showing an original image and a target image. We used genetic algorithms (GA) to search procedures. Utilizing a parallel searching function of GA and introducing the concept of era, we constructed hierarchical procedures of mathematical morphology.

Doctor Eng. paper: "Real-time recognition system for human-centered scene understanding"
  School of Engineering, University of Tokyo (Paper doctoral degree)
  To attain smooth interaction between a computer and its users, I proposed a system, which obtained depth information and optical flow from stereo gray multi resolution images, and simultaneously used these data to recognize regions nearest to the cameras of the computer. This system identified 1 to 3 nearest regions and recognized objects and their rough movements within the regions. In this method, I utilized higher order local autocorrelation features and linear discriminant analysis to recognize the objects. As the recognition method was a view-based method, the system could handle the face and hand recognitions simultaneously in real-time.

Master Eng. paper: "Study on visualization of multi-dimensional data by color information"
  Graduate School of Engineering, Tokyo Metropolitan Institute of Technology
  I researched visualization methods for multi-dimensional data by continuously using color information. In the Munsell Color System, colors are arranged in 3D space, consisting of the hue, value and chroma. I attempted to display all the components at the same time by using their properties. This method seemed to improve existing magnetocardiograms and has the advantage of displaying moving images. displaying moving images.

have the five dimensional variables at each sampling point, which are composed of the 2D coordinate and 3D vectors. Therefore it is difficult to display all the components of the vectors simultaneously.
In the method, the Munsell color system is used to represent the vectors.

Bachelor Eng. paper: "Study on visualization of multi-dimensional data for magnetocardiograms"
Faculty of Engineering, Tokyo Metropolitan Institute of Technology
I researched a new visualization method for displaying spatially distributed moving vectors. Some types of scientific data (for example, magnetocardiograms and magnetoencephalograms) have five- dimensional variables at each sampling point, which are composed of the 2D coordinate and 3D vectors, making it difficult to display all the components of the vectors simultaneously. In the method, the Munsell color system is used to represent the vectors.
