Motion magnification algorithms for video-based breathing monitoring
Biomedical Signal Processing and Control, 2023 In this paper, we present two video processing techniques for contact-less estimation of the Respiratory Rate (RR) of framed subjects. Due to the modest extent of movements related to respiration in both infants and adults, specific algorithms to efficiently detect breathing are needed.

3D Motion Magnification: Visualizing Subtle Motions with Time-Varying Radiance Fields
2023 IEEE/CVF International Conference on Computer Vision (ICCV), 2023 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.

Detectability of Orbital Motion in Stellar Binary and Planetary Microlenses [PDF]
, 2010 A standard binary microlensing event lightcurve allows just two parameters of the lensing system to be measured: the mass ratio of the companion to its host, and the projected separation of the components in units of the Einstein radius.

Frequency-Aware SVD Decomposition and its Application to Color Magnification and Motion Denoising
IEEE Access, 2021 Videos are full of dynamic changes along both the spatial and temporal dimensions. Large, jerky short-term motions make it difficult to extract significant changes from videos such as subtle color changes and long-term motions occurring in time-lapse ...

The Transverse Peculiar Velocity of the Q2237+0305 Lens Galaxy and the Mean Mass of Its Stars [PDF]
, 2010 Using 11-years of OGLE V-band photometry of Q2237+0305, we measure the transverse velocity of the lens galaxy and the mean mass of its stars. We can do so because, for the first time, we fully include the random motions of the stars in the lens galaxy in
