Pixel based experimental modal analysis [PDF]

This research proposes a novel method for modal identification that directly utilizes noisy pixel intensities from high-speed camera recordings. Typically, modal identification with high-speed cameras requires the identification of displacements as a first step, which is done by processing the video recording.
