A Thorough Investigation Into the ENF Reconstruction in Videos Exposed by Rolling Shutter

IEEE Access, 2023
In electric network frequency (ENF)-based video forensics, the analysis of videos captured by rolling shutter systems, where each row of a frame is exposed at different time instances, is critical. To gain the advantage of increased sampling frequency in
