Abstract
A source video of a scene showing moving objects, undergoing periodic motion in a field of view which may be located in a region of interest, is filtered and processed by constructing a representation such as a frequency spectrum plot of some of the frequencies of motion in the scene or region of interest and enabling a selection of frequency peaks representing one or more pixels in the field of view from which to generate reconstructed waveforms, then applying the reconstructed waveform at each pixel to a reference frame to produce a modified video recording.
