Nontarget Image-Based Technique for Small Cable Vibration Measurement
Y. F. Ji,Chih-Chen Chang +1 more
TL;DR: In this paper, a proof-of-concept image-based technique is proposed for measuring small cable vibration, which analyzes an image sequence of a vibrating cable segment captured by a camera and calculates variation of optical intensity of an arbitrary selected region of interest ROI on the cable image sequence.

Fast Localization of the Optic Disc Using Projection of Image Features
Ahmed Mahfouz,Ahmed S. Fahmy +1 more
TL;DR: This work presents a fast technique that requires less than a second to localize the Optic Disc, based upon obtaining two projections of certain image features that encode the x- and y- coordinates of the OD.
