About

While studying information science and technology, I do research, run a business and make art.

Portrait of Toma Okugawa

Toma Okugawa (奥河 董馬). I am from Yuge Island in Kamijima, Ochi District, Ehime, Japan, and I am a third-year student in the Department of Information Science and Technology at the National Institute of Technology (KOSEN), Yuge College. I work as a student, engineer, researcher and entrepreneur.

My research centers on low-light image enhancement, which makes images taken in dark places visible. Building on Retinex theory, I have designed methods that are fast and less likely to distort color and structure, and I have published them as papers and code. I also work on evaluating kyudo (Japanese archery) shooting form with real-time pose estimation, on regional policy analysis with small language models, and on entrepreneurship education based on failure cases.

As the Representative Member of Fieldlight LLC (registration in progress), I am developing Beacon, edge AI for inspection in dark places, and Kyudo AI, an app that scores kyudo shooting form, to turn the technology from this research into a form that can be used in the field. I also continue to make generative art, drawing lines with code.
