Analysis of ENF Signal Extraction From Videos Acquired by Rolling Shutters
IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY, 18, 4229–4242.
author keywords: ~Electric network frequency (ENF); rolling shut-ter; filter bank; multirate signal processing; multimedia forensics
TL;DR:
Analysis of two representative methods for extracting ENF signals from visual signals acquired by cameras using the rolling-shutter mechanism implies that the periodic zeroing-out method offers more accurate frequency estimates, but the performance improvement is moderate.
