Saburo Tsuji

Also known as 辻 三郎

Computer vision researcher Saburo Tsuji worked on world models, mobile-robot stereo imagery and active recognition with omnidirectional vision at Osaka University. Minoru Asada named him as his supervisor, and Hiroshi Ishiguro worked in Tsuji's laboratory as a graduate student at Osaka University. At Osaka and Wakayama, he held professorships, served as president of the Japanese Society for Artificial Intelligence, became an IAPR Fellow in 1996, and co-chaired ACCV'98 in Hong Kong. In March 2023, the Japanese Society for Artificial Intelligence published Seiji Yamada’s reminiscence of him in its journal.

Timeline

  1. 1982

    Minoru Asada's PhD

    Minoru Asada spends five years in Tsuji's computer-vision and robot-vision group and names him as his supervisor. He receives a Ph.D. in control engineering from Osaka University in 1982.

  2. 1985–1993

    Computer vision projects at Osaka

    He is a professor in Osaka University's Faculty of Engineering Science from 1986 to 1993. His KAKEN projects study world models in computer vision and environment modeling by a mobile robot using time-varying stereo imagery in 1985–1986. From 1991 to 1993, he leads a project on active recognition of the environment by omnidirectional vision.

  3. 1990–1992

    President of Japan's AI society

    He serves as the third president of the Japanese Society for Artificial Intelligence from 1990 to 1992.

  4. 1991

    Hiroshi Ishiguro's doctorate

    At Osaka University, Hiroshi Ishiguro works in Tsuji's graduate laboratory and receives a D.Eng. in systems engineering in 1991. Ishiguro describes him as a very famous professor in computer vision.

  5. 1994–1999

    Professor at Wakayama University

    He becomes a professor at Wakayama University in 1994 and serves in its Faculty of Systems Engineering from 1995 to 1999. His projects examine human facial-expression recognition based on a potential field in 1995–1996 and aspect representation of environments in 1997–1999.

  6. 1996

    An IAPR Fellowship

    IAPR names him a Fellow in 1996 for contributions to computer vision and outstanding service to the association.

  7. 1998

    Program co-chair at ACCV'98

    In 1998, he is one of three program co-chairs of the 3rd Asian Conference on Computer Vision in Hong Kong, with Roland Chin and T.C. Pong of HKUST.

  8. March 2023

    A JSAI journal reminiscence

    In March 2023, the Japanese Society for Artificial Intelligence publishes Seiji Yamada’s reminiscence of Professor Tsuji in its journal.

  1. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes University of Osaka. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  2. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes University of Osaka. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
  3. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes Osaka University. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  4. Google had the most people shaping AI every year from 2014 to 2025Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
