Vibration measurement plays an important role in the inspection and monitoring of civil
structures. In recent years, the computer vision (CV)-based method has gained significant …

Meibography is a visualisation technique that has been used for over 40 years. There have
been significant improvements in image quality, examination technique and image …

Video cameras offer the unique capability of collecting high density spatial data from a
distant scene of interest. They can be employed as remote monitoring or inspection sensors …

When sound hits an object, it causes small vibrations of the object's surface. We show how,
using only high-speed video of the object, we can extract those minute vibrations and …

Video motion magnification techniques allow us to see small motions previously invisible to
the naked eyes, such as those of vibrating airplane wings, or swaying buildings under the …

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 …

The estimation of material properties is important for scene understanding, with many
applications in vision, robotics, and structural engineering. This paper connects …

Optically-based vibration measurements can be used to determine the full-field dynamic
response of structures without the need of mounted transducers (eg accelerometers, strain …

In one embodiment, a method of amplifying temporal varia tion in at least two images
comprises examining pixel values of the at least two images. The temporal variation of the …

This paper presents a simple, self-supervised method for magnifying subtle motions in
video: given an input video and a magnification factor, we manipulate the video such that its …
