Visual Vibration Tomography: Estimating Interior Material Properties from Monocular Video

Kavli Affiliate: Chiara Daraio | First 5 Authors: Berthy T. Feng, Alexander C. Ogren, Chiara Daraio, Katherine L. Bouman, | Summary: 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 […]
