Areas of specialization	Image measurement, optical measurement, measurement engineering
Laboratory/research office	Image Processing and Informatics Laboratory Our research topics is image understanding and data understanding from various sensors and its application to real world. Camera outputs a large amount of data (some million pixels per 1/30 second) and it is required to develop effective utilizing method for such a vast data. Our research is based on physics and developing reliable image inspection system and image processing, understanding technique for human computer interaction.
