PPED (Periodic Phenomena Event-based Dataset)

PPED: Periodic Phenomena Event-based Dataset

The dataset features 12 one-second sequences of periodic phenomena (rotation - 01-06, flicker - 07-08, vibration - 09-10 and movement - 11-12) with GT frequencies ranging from 3.2Hz up to 2000Hz in file formats .raw and .hdf5.
