About Mitsuharu Matsumoto Laboratory

The long-term targets of our laboratory are to develop human-friendly science and engineering and to understand human and life from cross-disciplinary prospects. We progress our research projects not only from engineering perspectives such as information processing and mechatronics but also from scientific perspectives such as physics, chemistry, and mathematics. We also would like to feedback our research results to industrial fields and general public. 

Our laboratory progresses our researches on perceptual information processing such as image processing, acoustical signal processing and tactile information. Our researches also include human-machine interaction and intelligent robotics.

Perceptual information processing is interdisciplinary and strongly related to industrial field and general public. We would like to progress our research with balancing scientific perspective and engineering perspective.

From scientific perspective, we would like to understand life and human throughout human-machine interaction and to progress various researches such as:

- Verbal-nonverbal communications with visual, auditory and tactile/haptic information
- Feature extraction using image processing
- Self-replication of 3 dimensional structures by controlling the environment

From engineering perspective, we would like to feedback our results to welfare engineering, security field, automobile industry, and so on, and to progress various researches such as:

- Internal noise reduction from the system inside
- Object detection system and applications of our results to car and security system
- Applications of passive self-replication to automation
