Ground-truth compared with magnification results of our algorithm and other techniques. (a) A frame from SynVideo1, where we create a tiny vibration in the vertical direction when the white circle moves from left to right. (b–c) Linear EVM [6] and phase-based motion magnification [12]. (d) The ground-truth by 20 times magnification. (e) Motion acceleration magnification [17]. (f) Our proposed algorithm. Motion magnification using different magnification techniques can be observed by spatio-temporal slices at the red line. Compared against other techniques, our algorithm reveals the small motion and does not generate blurring artifacts.
