Phase-Based Video Motion Processing
VIDEO MOTION MANIPULATION
What is it ?
Phase-based motion processing is a technique that can be used to attenuate or amplify small motions in videos.
One of the main advantages of this technique is that its highly insensitive to image noise.

Use cases in the construction industry
PB motion processing allows for displacement monitoring of structures, it can help extract displacement vs time, from this data we can:
Identify exact moment damages occur in buildings by monitoring abrupt changes in displacement data.
Identify natural frequencies and mode shapes of the structure being studied and compare with design values.
In disaster areas, Phase-based motion magnification could be used to monitor structural health of damaged buildings without putting human lives at risk.
