Vision Sciences and Human Interfaces

NEXT
PREV
Features

We study human vision and use the knowledge of the vision system for image sciences. Our research focuses on vision sciences from early to high level processes. Target processes include early passive visual processes such as motion, depth and color perception, and high level processes such as attention, interaction between vision and haptic perception and implicit effect of the perception. Our approach includes visual psychophysics, brain activity measurements, and computer modeling.

Targeted Application(s)/Industry

We apply the knowledge obtained from the basic research to propose methods to evaluation of displays, image contents, visual environments, and so on.

Visual Computing with Secure ICT in the Big Data Era

NEXT
PREV
Features

Our study focuses on sensing, processing, recognition, understanding, and analysis of enormous visual data collected in real-world environments. We have invented a set of advanced techniques of sub-pixel image analysis using phase-based image matching. Potential applications include personal recognition using various biometric traits (e.g., face, fingerprint, palm print, finger knuckle print, iris, and medical radiographs), machine vision, multi-view 3D reconstruction, image database search, and medical image computing. We are also studying fundamental techniques for building secure ICT infrastructure for the big data era; our research interests include tamper-resistant cryptographic processing and biometrics-based secure remote authentication.

Targeted Application(s)/Industry

We can provide collaboration and information exchange services for industries and other research organizations in the fields of image processing, computer vision, information security, biometrics, LSI design, and embedded system technologies. Many researchers and engineers from various companies, universities, and research institutions have visited our laboratory regardless of their technology fields. Our staff at the Intelligent Information System (IIS) Research Center will welcome potential collaborators: info@iisrc.ecei.tohoku.ac.jp

Visualization of Biological Microstructure with High Frequency Ultrasound and Photoacoustic Imaging

NEXT
PREV
Features

"Features"
High-resolution imaging of biological tissue is non-invasively obtained with high frequency ultrasound. We have developed some ultrasound microscope systems which realized the resolution of 15-micron with 100 MHz and resolution to visualize a single cell with GHz range ultrasound. Ultrasonic imaging provides not only tissue morphology but also information on tissue elasticity. Recently, we have developed a real-time three-dimensional photoacoustic imaging system for visualization of subcutaneous micro vasculature and oxygen saturation.
"Targeted Application(s)/Industry"
High frequency ultrasound and photoacoustic imaging is repeatedly and non-invasively applied for early diagnosis of atherosclerosis, skin aging and tissue metabolism. They are useful for efficacy assessment of cosmetics and pharmaceuticals. High frequency ultrasound is also applied in the industrial areas where thickness measurement of opaque film or bilayer thin coating with the precision of 0.1 micron is required.

Visualization of Electron Motion in Matter by Means of Electron Compton Scattering

NEXT
PREV
Features

Properties of matter, such as reactivity and functionality, are determined by the motion of the constituent electrons. For this reason we aim at developing new spectroscopic methods, by using electron Compton scattering, that would visualize the electron motion for stable species and most importantly the change of electron motion in transient species, which is the driving force behind any chemical reactions;
(1) development of molecular frame electron momentum spectroscopy for momentum-space imaging of molecular orbitals in the three-dimensional form,
(2) developments of multiparameter coincidence techniques for studies on stereo-dynamics in electron-molecule collisions,
(3) development of time-resolved electron momentum spectroscopy for visualization of the change of electron motion in transient species.
We hope to conduct collaborative research with a willing company for a practical application of this technology in industry, and we are also prepared to provide academic consultations to companies interested in our research.

Visualization of supply chain risks from the resource logistics perspective

NEXT
PREV
Features

With the increased global concerns of resource and environmental constraints of recent years, the role of mining, as a constituent of social responsibility associated with resource extraction and usage, is becoming increasingly important in the science, technology, and innovation policy. Under increasing public and shareholders' concerns of social and environmental sustainability, the fabrication industries require careful attention owing to their own risks related to the resources and materials that are used in their products and services. The Material Flow Analysis tool and Input output technique provide useful perspectives and valuable evidences for avoiding or minimizing the social and environmental risks related to the demand of resources.

Targeted Application(s)/Industry

Our developed model evaluates the risk weighted flow analysis by combining the resource logistics database and Global Link Input Output model. The estimated results shed light on how resource logistics prepares policy makers and R&D engineers to confront the risks behind resource usage and how the information should be shared among the stakeholders.
