In our lab, students can learn physics (quantum mechanics, statistical physics, solid state physics, …) and computer science (algorithm, programing, information theory, …). By combining these two fields, we will study future cutting-edge computation technology such as quantum computer (noisy intermediate quantum devices and fault tolerant quantum computers ) and quantum annealing.

I would like to emphasize that it is only through the accumulation of basic knowledge and the necessary detours that we can do fundamental and creative work that does not become obsolete. I believe that this should be acquired through one’s own experience and appropriate guidance from the time when one is a student with relatively ample time.

My research focuses on image processing and recognition. Images have much information on the objects, for example, remotely sensed images include spectral, spatial and temporal information about terrain objects, and face images personal information. The main purpose of the image processing is to extract the information by using various techniques. Noise reduction is one of very important processing in these techniques. The information extracted is then generalized with the physical properties (priori information) and is used for recognizing “what or how is the object”. The recognized results are used as sources of digital media. I want to realize smart recognition like human. My current research interests are image processing in remote sensing, medical image processing and person recognition from face image. My hobbies are reading and gardening.

Our lab is studying how to develop software systems, especially, with visual and interactive properties. Although such systems are becoming increasingly important and widespread, the method of their development has remained unchanged for over twenty years; people have been using object-oriented imperative programming languages (e.g. C++, Objective-C, and Java) for this purpose. We are tackling this situation by adopting mathematical approaches such as constraint programming. We welcome your participation in our activities.

Find your own winning way in the game of theoretical thinking that involves lots of mathematics and scientific discovery. While playing this game, we apply the dialogue engineering (or dialectical) technique. Dialogue may be sometimes monologue, where dialogue occurs between one and oneself, and, of course, dialogue may be actual dialogue in seminar talks and other presentations. My main research theme can be termed as dialogue engineering.
