title: 3D Motion Magnification: Visualizing Subtle Motions with Time Varying
    Radiance Fields
summary: Motion magnification helps us visualize subtle, imperceptible motion.
  However, prior methods only work for 2D videos captured with a fixed camera. We
  present a 3D motion magnification method that can magnify subtle motions from
  scenes captured by a moving camera, while supporting novel view rendering. We
  represent the scene with time-varying radiance fields and leverage the Eulerian
  principle for motion magnification to extract and amplify the variation of the
  embedding of a fixed point over time. We study and validate our proposed
  principle for 3D motion magnification using both implicit and tri-plane-based
  radiance fields as our underlying 3D scene representation. We evaluate the
  effectiveness of our method on both synthetic and real-world scenes captured
  under various camera setups.
