Shinji Ozawa

Also known as 小澤愼治, 小沢愼治, 小沢慎治

Shinji Ozawa is a Japanese researcher in computer vision and motion analysis whose image-processing work ranges from road scenes to sports video. He studied electrical engineering at Keio University, joined its engineering faculty as an assistant in 1970, and was a professor by 1988. In 1986 he received an annual best-paper award from the journal Pattern Recognition for applying moving-image processing to traffic measurement, and in 2000 he became a Fellow of the International Association for Pattern Recognition for contributions to motion analysis and service to the association. His Keio projects covered active-camera tracking, lane detection on rainy roads, super-resolved images from a moving camera and interactive soccer video, and from 2009 he led a sports-scoring project as a professor at Aichi University of Technology. He is a Professor Emeritus in the Faculty of Science and Technology at Keio University.

Timeline

  1. 1967–1974

    Engineering studies at Keio

    He graduates from the electrical engineering department of Keio University's Faculty of Engineering in 1967 and completes a master's course in engineering there in 1969. After finishing the requirements of the doctoral course in 1972, he receives a degree in engineering from Keio in 1974.

  2. 1970–1988

    From assistant to professor

    He joins Keio's Department of Electrical Engineering as an assistant in 1970, becomes a lecturer in 1975, and an associate professor in 1981. By 1988, he is a professor in Keio's Faculty of Science and Technology.

  3. 1986

    A Pattern Recognition award

    In 1986, he receives an annual best-paper award from the journal Pattern Recognition for applying moving-image processing to traffic measurement. With A. Rosenfeld, he also publishes "Synthesis of a Road Image as Seen from a Vehicle" in Pattern Recognition in February 1986, proposing a model of road images seen from a vehicle.

  4. 1995–1998

    Active cameras and lane detection

    From 1995 to 1996, he leads a Grant-in-Aid project on tracking moving targets with an active camera, where a new camera built around an image processor runs all image processing at video frame rate. From 1997 to 1998, he leads a project on detecting the ego lane under rainy conditions, extracting lane-marker candidates from images taken by a camera on a running car.

  5. 2000

    An IAPR Fellowship

    He becomes a Fellow of the International Association for Pattern Recognition in 2000, with a citation for contributions to motion analysis and for service to IAPR.

  6. 2000–2004

    Super-resolution and soccer video

    From 2000 to 2001, he leads a Grant-in-Aid project at Keio, with Hideo Saito, on synthesizing super-resolved images by merging frames taken by a moving camera, using the factorization method to recover object shape. From 2002 to 2004, a further project builds an interactive soccer video generation system that uses scene analysis of multi-camera images to produce sequences from an assigned viewing direction.

  7. 2009–2011

    Professor at Aichi University of Technology

    From 2009, he is a professor in the Faculty of Engineering at Aichi University of Technology. His 2009–2011 Grant-in-Aid project there develops an automatic scoring system for performance sports, using a skeleton model of each player's pose.

  8. As of October 2026

    Professor Emeritus at Keio

    He is a Professor Emeritus in the Faculty of Science and Technology (Mita) at Keio University, where he joined the electrical engineering faculty as an assistant in 1970.
