Visual Surface Wave Elastography: Revealing Subsurface Physical Properties via Visible Surface Waves

Alexander C. Ogren, Berthy T. Feng, Jihoon Ahn, Katherine L. Bouman, Chiara Daraio

ICCV 2025poster

Wave propagation on the surface of a material contains information about physical properties beneath its surface. We propose a method for inferring the thickness and stiffness of a structure from just a video of waves on its surface. Our method works by extracting a dispersion relation from the vide…

Visual Vibration Tomography: Estimating Interior Material Properties From Monocular Video

Berthy T. Feng, Alexander C. Ogren, Chiara Daraio, Katherine L. Bouman

CVPR 2022oral

An object's interior material properties, while invisible to the human eye, determine motion observed on its surface. We propose an approach that estimates heterogeneous material properties of an object from a monocular video of its surface vibrations. Specifically, we show how to estimate Young's m…
