# Deepfake detection from your pulse guide (@harixganesh)

> Plain-English guide to spotting deepfakes from the pulse visible in skin colour (remote photoplethysmography, as in Intel's FakeCatcher), plus a weekend-sized Python build plan: OpenCV + MediaPipe face landmarks, band-pass filtering and FFT with SciPy/NumPy, patch coherence, a simple classifier, and honest pitfalls (compression, short clips, skin tone, ~91-96% claims).
