Image Processing for Capturing Motions of Crowd and Its Application to Pedestrian-Induced Lateral Vibration of a Footbridge
Autor: Junji Yoshida, Yozo Fujino, Toshiyuki Sugiyama
Publikováno v: Shock and Vibration, Vol 14, Iss 4, Pp 251-260 (2007)
An image processing technique to capture motions of crowds is proposed and it is applied to understanding pedestrian-induced lateral vibration in a footbridge. Firstly, an outline of recording sequential images of vibration in the bridge is described

Concrete Crack Detection by Multiple Sequential Image Filtering
Autor: Takafumi Nishikawa, Junji Yoshida, Yozo Fujino, Toshiyuki Sugiyama
Publikováno v: Computer-Aided Civil and Infrastructure Engineering. 27:29-47
This article presents a new robust automated image processing method for detecting cracks in surface images of concrete structures. This method involves two steps: (1) development of an image filter for detecting major cracks using genetic programmin

Rattling Thresholds of Windows and Doors by Ground Vibration
Autor: Shuhei Sano, Toshiya Kitamura, Shin-Ya Imai, Shinji Yamada, Hiroyuki Yamada, Masaki Hasebe, Toshiyuki Sugiyama
Publikováno v: Journal of Low Frequency Noise, Vibration and Active Control. 25:261-266
This paper reports the rattling thresholds of windows or doors caused by ground vibrations. The frequency characteristics of the threshold curves by vertical and horizontal vibration were measured. The threshold for horizontal vibration is lower than
