Researcher

Atsushi Imiya

Also known as 井宮 淳

Atsushi Imiya is a researcher in computer vision and pattern recognition whose work spans signal smoothing, randomized Hough methods, optical flow and discrete geometry. He published a generalized Lanczos method for signal smoothing in 1986 and applied the randomized Hough transform to piecewise-linear signal detection in 1996. His work on featureless robot navigation used optical flow in 2005, and he became an IAPR Fellow in 2008 for contributions to randomized model fitting and discrete geometry. At Chiba University, he led projects on computing mean organ images for clinical diagnosis in 2009–2011 and model-based longitudinal analysis of dynamic multi-modal higher-dimensional data in 2020–2024; he held a Doctor of Engineering from Tokyo Institute of Technology by 2024. As of October 2026, he is a Chiba University emeritus professor.
