screenpad-data
Data for the screenpad take-home PAD project: 1000 bona fide face images (Bonafide/, apparently FFHQ, CC BY-NC-SA 4.0) and 23 phone recaptures of some of them shown on a screen (Screens/, same filename as the source image; iPhone 15 x14, Galaxy A12 x9). The attack images were provided by the assessors for the assignment.

|---|---|---|
raw/screenpad-raw.tar, raw/screenpad-raw.sha256 |
the original files, byte-identical, in one uncompressed tar, with per-file SHA-256 | screenpad pull-data (verifies every file) |
data/ |
the same files uploaded loose (first upload; slow to fetch, kept for browsing) | |
cache/crops_{loose,tight}_384[_aligned].npz |
preprocessed face crops (384 px; loose = 1.25 x, tight = 1.0 x the face box; aligned = eye line levelled), each verified byte-exact against a fresh recompute | screenpad pull-data --cache |
cache/synth_{loose,tight}_384_train-val.npz, cache/synth_params_384_train-val.csv |
synthetic screen recaptures and camera-only controls of train/validation faces, with every sampled simulator parameter | screenpad pull-data --cache |
cache/shrink_{loose,tight}_384_aligned.npz |
resized bona fide crops for the resampling-shortcut test |
Splits (by image ID) are made by screenpad splits; no test image is used to make any cache except the plain crops.
