Previous approaches using event cameras have estimated vibration frequencies but have struggled to accurately recover the amplitude and phase information. Incorporating topological data analysis, a ...

An event camera–based system, “Event topology-based visual vibrometer,” that measures vibrations of objects without physical contact. The image illustrates the measurement of a guitar string. By ...

When shooting 24 fps images with a regular camera, 24 still images are captured per second. In the case of slow motion video, shooting with 120 fps or 240 fps, etc., with an extremely large number of ...

Event cameras, also known as neuromorphic cameras, detect relative changes in brightness at the pixel level. Instead of frames, they output a stream of brightness change events: (x, y) pixel location, ...
