资源简介：
"FS2AI (From Screenshot to AI-Generated) is a multi-source PNG dataset for fine-grained encoder \/ pipeline provenance: 16 sources spanning desktop and mobile screenshots and AI\/synthetic exporters. Images are organized under per-source folders with filenames encoding five benchmark content types (01\u201305). The recommended release includes dataset_source_normalized\/ for Exp.1\u20136 (canonical basenames; files that were JPEG payloads with a .png extension are renamed to .jpg without changing bytes). An optional dataset_sns\/ provides QQ \/ WeChat re-encodings for SNS robustness (Exp.5). Supported tasks include 16-way closed-set attribution, content invariance, feature and training-data ablations, cross-domain few-shot transfer, and, when SNS data are included, platform re-encoding robustness. Unless noted otherwise, experiments follow a stratified 8:1:1 split with a fixed random seed. Exp.3c JPEG re-encodings are generated at runtime from a PNG subset and are not bundled in the release."
