The paper proposes a variant of implementation of a filter for the amplification of the low-amplitude object vibrations in the video stream, describing the stages of the filter design. For this purpose, we conduct a mathematical analysis of the nature of vibrations and more complex movements of objects in the frames. The performance of the filter for movement amplification is tested, showing the feasibility of the non-contact determination of human respiration rate.
