    • Behavior measurement using image processing【Instructor: YONEYAMA】

      Among the many methods of behavior measurement, this course focuses on behavior measurement using image processing, which is non-contact and non-intrusive to the target fish, and teaches how to detect and track the position of fish (moving objects) by performing image processing of video and image data.
