Supervisor
Prof. IWAHASHI Masahiro, Assistant Prof. HARAKAWA Ryosuke, Mr. YAMAURA Kentaro
Prof. Iwahashi is a person with wide range of knowledge in image processing, who actively conducts various joint researches. Assistant Prof. Harakawa is a specialist in multimedia and a very eager teacher. Meanwhile, Mr. Yamaura is a person in charge of the technicals and will gladly help you if you were facing any technical problem.
Research Content
As researches on multimedia signal processing to support AI and IoT technologies, we conduct researches on "image restoration," which restores desired images from incomplete observed images, and "image recognition," which detects objects and classifies their states based on deep learning. Moreover, as researches for multimedia data such as sounds and texts, we conduct researches on "semantic understanding" to reveal useful information from big data in the cyberspace. Notably, we often collaborate with researchers and companies in various fields such as robotics, physics, biology, environment, disaster prevention, and education.
Discussion in the seminar
A Day in the Lab
In this laboratory, we hold a seminar twice a week to discuss our researches and to train for presentations. No need to worry about the lack of experience or knowledge, because you can always ask our professors and/or read the books. In addition, many members actively present their researches through conferences and papers, both in Japan and abroad. Before the COVID-19 epidemic, we have held futsal/softball tournaments, cherry blossom viewing, Nagaoka fireworks, and laboratory trips among members. After that, we have continued to hold various events using online tools and other means, and our members get along with each other.
