ABSTRACT
This paper demonstrates how novel motion-enhancing computer vision techniques can use high-speed video cameras to see and quantify the vibrational mode shapes of simple structures. Motion magnification is an algorithm designed to magnify the subtle movements of video footage. The basic principle of the algorithm is to obtain a representation of the video that allows time-frequency bandpass filtering, amplification and reconstruction of the signals corresponding to the motion of objects. This process results in a video in which the apparent motion of objects is amplified within a given frequency band.
